7 signs your knee injury could be serious

Knee injuries are among the most common injuries in sports and exercise. Fortunately, among the patients I see in the office, most knee injuries do not require surgery.

If you suffer a knee injury, how can you know if it is serious and worth seeing an orthopaedic surgeon? This list is far from comprehensive, but here are seven signs you have a knee injury that might require surgery.

It goes without saying that the information in this post, like all of my content on this blog, on my podcast, and in social media, is not intended to provide specific medical advice. Please consult your doctor for any medical concerns.

Your knee is swollen.

It might not be a big deal for your knee to have a small amount of fluid present. On the other hand, if your knee swells up like a basketball in the first few hours after an injury, you could have an ACL tear or fracture.

You heard a pop.

I don’t mean a small pop like the one you feel when you crack your knuckles. I’m also not talking about the popping many of you feel under your kneecaps normally with knee motion. If you hear or feel a loud, painful pop during an awkward landing or when you get hit in the knee, you could have torn a ligament. Many athletes say that their teammates heard the pop when they tore their ACLs.

You can’t bear weight.

Knee injury in soccerExtreme pain trying to walk is somewhat of a generic complaint. Many injuries can be serious enough to cause pain when you try to put pressure on the injured leg. It is still a sign you might consider seeking medical attention.

Your knee buckled or gave way.

If your knee buckled when you landed from a jump or changed direction suddenly, you could have suffered ligament damage, such as an ACL tear. Alternatively, if you experience your knee giving out with twisting or landing movements in sports weeks or months after an injury, you should consider seeing a sports medicine doctor. True knee instability with activities can risk further damage to the meniscus or articular cartilage.

Your knee is locked.

Younger athletes can often tear the meniscus in such away that the inner, torn fragment can flip into the center of the knee and block motion. These bucket-handle meniscus tears often require surgery. The surgeon must push the meniscus back into place and repair it with sutures or anchors. Milder or more chronic forms of knee locking or catching also can suggest you have a meniscus tear.

You cannot fully extend the knee.

Pain, swelling, and inflammation after acute injuries can all make knee range of motion difficult. If a patient comes to my office days after an injury and I can’t straighten the knee, I get at least a little concerned. It can be a nonspecific finding, though. Regardless, I have often found ACL tears, acute meniscus tears, patellar dislocations, and more in these circumstances.

Your knee hurts in a very specific location.

Patients with meniscus tears usually complain of pain in a very specific spot along the joint line rather than throughout the knee. Medial meniscus tears often hurt along the medial (inside) and posterior (back) side of the knee. Lateral meniscus tears often cause pain along the lateral (outside) and posterior aspect of the knee. Likewise, stress fractures usually cause localized pain on the bone at the site of the fracture.

I hope that this list is helpful. Again, it is not comprehensive and not intended to replace the advice of your doctor. If anything, I hope you would consider seeing your doctor sooner after injury if you have any of these complaints.

Sports medicine professionals – athletic trainers, physical therapists, and orthopaedic surgeons – are there any other findings you would add?

    • I have had knee pains and IT band problems in both to left and right for over a year. Physical therapy helped after 4 months then the same pains came back. I also recieved cortisone shots in both and that did not do anything at all. Through an MRI my ortho doctor said I was born with a crack in my left knee cap and the bottoms of my knees that cause loud cracking are rough but he said nothing was wrong???? Is this something I should be concerned about? And what can I do I have pretty constant pain and am in the military so I am extremely worried please email me back as soon as you can. Thanks

      • I can’t really offer you too much advice without being involved in your care. Generally we don’t worry as much about popping in the knee, as many people have it despite having no pain. It can also be a sign of arthritis changes under the kneecap, and there aren’t easy treatments for that. You could discuss options for your pain with your orthopaedic surgeon.

        • how would i know that i did something to my kneecap. It is swollen and looks dislocated and hurts to bend or more and it hurts to bear weight.

          • I landed from a jump wrong and I felt my knee pop sideways or outwards. I can straighten my knee, but it is with pain and if I bear weight there’s a feeling of instability. I can’t straighten my knee when I walk or it will buckle. However, I can’t find any visible or obvious swelling?

      • I was at track practice sprinting and went to go tag my partner to go and I didn’t hit him but he still went but I went to hit it and I stepped on my lefted leg and my knee just did something and it didn’t hurt until like 10 seconds and I went off to the side and just dropped dead my knee never felt worse (it felt like it poped and I can’t keep my leg straight only when it’s off the ground)and I had to run another lap and it was painful but good news is I won but my leg…not so much

    • I can extend my knee fully but it is hard and comes with pain at the bottom of my knee cap, I had jumper’s knee for 2 years. I can walk fine and go up stairs, coming down gives me some pain at the bottom of my knee cap, did I partially tear my patteller tendon?

      • It is hard to know without examining you, but pain at the insertion of the patellar tendon into the patella, especially with a small defect and difficulty performing a straight leg raise, could suggest a partial patellar tendon tear.

        • I fell and all my weight landed on my knee yesterday. On concrete. No swelling, doesn’t hurt to the touch, does hurt when I kneel, and only time it hurts is when I lock my leg. I can walk and run without pain. Only when I lock it. What do I have???

          P.s I have aau basketball tryouts tommorow

          • I had the exact same thing happen to me, walking and running are fin, only when i like kick out my leg that I feel something. What happened to you?

    • Someone pushed me outside my door I fell on my knee hard two weeks later it still hurts right below my knee cap under the soar…and when I been or gets into my bed my back calves hurt like its fluid or swollen but I have no fever but my back leg is still in pain and when I’m on my knees there’s a lot of pain still is something tore or broken??

    • I fell with all my weight straight on to my knee playing soccer two years ago almost. It was very painful at the time but gradually got better. Ever since then I randomly get a numb, aching pain in my knee. It can vary in severity and is really starting to bother me. Do you have any recommendations on how to relieve this? And to stop it occurring? Any help would be greatly appreciated.

      • Without knowing what is causing the pain, I can’t really suggest treatments to make it better. I generally recommend that if a person has symptoms that keep him from doing what he wants to do as well as he wants to do it, he should consider seeing an orthopedic surgeon.

    • I landed really hard on my knee during a Vball match and I kept playing but it buckled one me once or twice and hurt to put pressure on through out the game and I could jump on it or push off it. Through out the day it continued to hurt but I was able to put more weight and move more on it, eventually I could jump. It’s now 5 days later and I still can’t bend it all the way with out a lot if pain and it’s still swollen on the outer side of my knee. I can’t decide wether I should get it looked at or not? If it’s just a muscle bruise I don’t want to go to the doctors I don’t want to be a hypochondriac. Do you think it’s something that needs to be checked out or can I get away without getting it checked?

      • If an active person has pain, swelling, limited motion or some other symptom that limits the ability to play as well as he or she wants to, it can be a good idea to see an orthopaedic surgeon or doctor to find a diagnosis and get a treatment plan.

    • I went to see my doctor and got a xray 2 weeks ago and they told me there was nothing wrong with my knee its been 5 months I had this injury and I even went to the county hospital n they told me they couldn’t do anything about it I have to go to my family doctor so I did n Idk if I might of tore a ligament? Or something?

    • I’m a relatively active 50 year old female. I went sea kayaking for 4 hours about a week ago, something I’ve never done before. My legs were,slightly bent and pointing a little outwards for the whole trip. I had a lot of pressure on my legs, using peddles to steer in substantial current. I think the left one was a little shorter, so my knee was under more stress.

      I felt fine for 2 days. Then, about 4 days ago, my knee felt swollen. It’s been tender and weak. Mostly an awareness that’s something wrong. It gets intense if I try to turn my left foot inward. I can walk ok. It feels better in the AM, but as the day goes on it gets worse.

      I have iced it a few times and am taking advil. Any ideas if something for stretched or torn? Thnaks

      • Honestly it would be hard to say with those symptoms. If pain or other symptoms are getting worse or not improving, it can be a good idea to see a doctor to find out a cause.

    • I just hurt my knee playing soccer yesterday. I was running tried to move direction, heard two loud pops, and felt my knee move inward. I can walk on it but it hurts a lot. I know it’s not broken or anything. Should I go to the emergency where they can do x rays, or to an orthopedic?

      • Generally I think seeing an orthopaedic surgeon is helpful for most athletes after that type of injury.

  1. I was diagnosed with a sprained knee never got better had an MRI the day after I felt a pop and very painful

  2. Hello,
    I severely dislocated my knee cap six weeks ago. I have been walking on it for two weeks and making huge progress. However, I am not able to completely straighten my leg. The MRI showed no meniscus/ACL issue. I am in physical therapy however my leg just won’t straighten. What could this possibly be? I am very concerned and worried.

    • Without being involved and examining you, I can’t say if there is some mechanical block to extension, like a meniscal tear. Generally though, the lack of full extension of the knee could be serious. An orthopaedic surgeon can perform an exam and order an MRI if needed to find the problem.

    • hi i had niggly pain in my knee 2 days late my left knee had swollen up no pain or tenderness i havent injured it i can walk and do daily things as usual its just strange how it has swollen up and feels tight around the knee.

  3. A day ago i was running and i fell right on my knee iits red and i can bearly straighten my knee and im just laying doown its really hurting for no reason i can even reall walk right

  4. I am going to try to summarize. A ski injury created partial tears in all ligaments in my right knee except meniscus. Had a mri and determined to be an extreme knee injury by an orthopedic surgeon Fast forward several years and I now get short periodic pain and failure to be able to fully extend leg. This pain is severe and last less then a day until I feel a pop or release. Immediately there is total relief of pain and a knee that is as normal as can be.
    I still ski, golf, hike and bike on a regular basis. Hard to get examined because it disappears.
    your best guess?

    • Without really being able to examine you and determine where in your knee the pop was coming from, I’m not sure I can point you in any particular direction. Sorry!

  5. In 2011 i triped and fell whilst out running on a pavent stone,and went down on my right knee,i went to the hospital they xrayed it and said there was nothing wrong with it,just bruised,Well several weeks later i was in the shower,and found when i put hot water on my left leg below knee i could feel it,But when i did the right it was totally knumb,I then got severe back ache and the hospital did a mri scan,to find my l3 l4 nerves were trapped in my spine,since 2011 ive had an operation on my spine and an operation on my knee,Could you tell me would this be the result of me falling and landing on my knee in 2011,at that time i was 52,im now 55,and disabled,need to wear knee brace without knee collapes,thank you,neil horne,huddersfield,uk.

    • I can’t say without examining you and looking at x-rays and an MRI. A patient with buckling or giving way of the knee might consider seeing an orthopaedic surgeon to see if any ligamentous injury exists.

  6. A person twisted my leg the wrong direction and my knee popped out I have had x ray and everything is still in tact but for the life of me I cannot bend my leg can’t force it either with hand what could be up with that?

    • Without examining you, I can’t really say. It is possible for a patient to have a mechanical block to motion (such as a loose body). An orthopaedic surgeon could deteremine if one exists and what it could be.

  7. long history with left knee…
    Medial tibial plateau fracture 7 years ago (I was 32 at the time), Schatzker 4 variant w/popliteal involvement. Several surgeries later, including fem-pop bypass & lateral uni-compartmental knee replacement.
    fast forward to current – we moved out of state, and can’t find an orthopedic surgeon to take my case (0 for 5). I’m “too high risk” because of the bypass, and I’m “too young” for even the uni-replacement – let alone consider doing anything further.
    The medial side of knee joint hurts sharply with any weight bearing, and I particularly can’t straighten it while standing/walking. It sorta feels like I’m culturing a pearl in there (If I had to imagine what an oyster goes through!), and it feels like my kneecap is grinding against sandpaper.
    Can’t feel anything on the lateral side – but then again, I have a hunk of metal on that side from the uni.

    ..without examining, of course, is this something that I simply have to live with? or should I start throwing darts at the orthopedic section phone book again?

    • I understand your frustration, but without being able to examine your knee and review studies, I can’t give you any specific answers to your questions. You might try the AOSSM website and use its Find a Doctor tool to find an orthopaedic surgeon in your area.

  8. I have had a history with my left knee, however at volleyball I jumped and heard and felt 2 pops, painful but I continued to play as I tolerate pain well. What are your suggestions?
    Please and thanks

  9. hi my name is adelaide burling i am 22 year old and i have a most common left knee injury and what happen was that i did my acl and i buckled my postier ligament it gotten to the point where i have joint effusion and plus the swelling of my left knee as been increasing and i have not been able to been able to get a opporation done yet due to western health footscray hospital recieptionist said to me it could weeks or longer so i had no choice and when it was july i found that i am pregnant and plus it stuffed up my chances of having my left knee injury done so i have to wait until the baby comes by next year though .

  10. i have popped my knee several time before. Like 5 by now. I had physical therepy and it helped, but it stayed in a weird position, a little turned the right than usual. It began to hurt so much i began to massage it and then i pushed the bottom part in by accident. It felt releiving for a moment but then it got swollen and it hurts worse now, also i feel something wants to pop out lately. I am really, really, really, scared, actually terrified, and incredibly worried .

  11. i want to stand and my knee pop i hadto sit right down it was instant paini took pain meds and used a hot pack then an ice pack it stop hurtin a bit but it hurts when i stad or try to move it a certain way i had a little swelling i can move it side to side without paind and i almost straighten it all the way out but it hurts when do what should i do next?

  12. I hurt my knee 2 yr ago and they said i had a strained mcl and acl and needed physical therapy i was supposed to do 3 or 4 weeks and only completed 1 now i can’t run at all and the other day i got hit by go kart and now my knee hurts to walk on and locks up what should i do

    • If a loose flap or piece of articular cartilage broke away, partially or completely, it could catch between the femur and tibia with range of motion.

  13. I got a knee injury last Saturday. I was riding a long board and I tried to get off my foot went into a curb and my left knee twisted to the left and I heard a loud pop. After going to the er they couldn’t tell with an x-ray so they sent me to the orthopedics. Thin is the ortho kept talking over me. I didn’t get to tell him I can’t bend my knee. I can almost straighten it but I can’t bend it into a sitting position. Any ideas what it might be?

    • I can’t tell you in your case specifically. Lack of flexion early after a knee injury can be related to swelling within the joint. It can also be caused by some block to motion, like a meniscus tear or loose piece of articular cartilage.

  14. I had no injury what so ever, had bad knees since i was 11.

    last week my keft knee started feeling uncomfortable to walk on, and everyday since then has gotten worse, now 11 days after still getting worse(Pain started day 9 followed by cracking) . The 7th day got a mri and the conclusion of my results:

    – Abnormal Patellar and Trochlear Morphology and Patellar Malalignment.
    – Grade 3 Chondromalacia Patellae.
    – Infrapatellar Fat Pad Impingement.
    – Joint Effusion with Synovitis.

    Im seeing the surgeon tomorrow as apprantly i need surgery this week before i end up crippled.(im only 23)

    i was originally seeing him for my right knee as ive had multiple dislocations on my R knee for the past 10 years and only in the past 7 months, ive had daily dislocations everytime i walk, so not sure if that would have anything to do with my left knee.

    (So, now im having surgery on my left knee, Then my right knee.)

    So my Question is, do you have any opionions on this?

    Thank You

    • I can’t really say too much without examining you and looking at your studies, so your orthopaedic surgeon should be able to help more. Patellar instability, especially when caused by bony abnormalities of the femur, can be a tricky problem and often requires extensive surgical procedures.

  15. I landed heavily straight on my knee whilst playing futsal. Immediately felt pain and that it wasn’t aligned correctly. It felt as though my foot was facing out more. Hobbled to the bench where I then tried to find out what was wrong. Can’t bend my leg back sometimes as is locking up. And hurt a lot that night when rolling over in bed with the twisting motion. I can straighten it and put weight on it to walk. Am going to a doctor today but interested to know your thoughts with what it might or might not be.

    • It’s hard for me to say without examining your knee. Inability to straighten the knee or bear weight are some of the signs for a potentially serious knee injury.

  16. I’ve never had an injury to either one of my knees. However, I do have severe neuropathy. I am unable to bed either one of my legs to walk. It’s like having two baseball bats attached at the hip. I’ve had a CT of the spine which showed a herniated disc at T8-T9 as well as an EMG which just showed that I have neuropathy. I have seen 5 different neurologists and none of them have ever seen “postured” legs like mine that just won’t bend. I am able to bend my legs to sit, but thats about it. My calf muscles are always tight, they never relax… they are always contacted. Any advice you have.. Im all ears! Thanks a lot

  17. I twisted on my knee when getting up after sitting on the floor. I now cannot extend my knee fully and have pain in my calf when trying to do so, I can walk pain free on a slightly bent knee. This happened today should I seek help or rest and pain killerss
    Thank you

    • I can’t tell you what to do. Generally I think seeing an orthopaedic surgeon for a knee injury that is not improving is a good idea for many people.

  18. I was playing soccer about 2 months ago when I twisted my left knee funny. I couldn’t straighten it out fully for about 5 days then I could but it still hurt. It hurt mildly sometimes then I went sleding and stacked it and after I stopped tumbling my knee hurt like really bad. It hurt around the front/lateral side and is extremely painful if I put weight on the sides of my knee. I get sharp pain and then constant pain. There is thus thing that clicks if u rub your finger on it above/beside my knee cap on the lateral side which wasn’t there before. It has been two weeks now and it us no better. What do u think it is

    • I really can’t say without examining it/you. You might consider seeing an orthopaedic surgeon if you still have trouble weeks out from the injury.

  19. My sister who is 14 has a history of knee problems and in July her knee locked up and doctors at the time thought that she had torn the meniscus in her right leg even though they did not carry ANY x-rays or MRI scans. Nearly 3 months on she still can’t put any weight on the leg even though she’s been receiving hydrotherapy and physio and is in a lot of pain. I’d be interested to know your thoughts

    • I don’t know that I can shed much light on it without being involved as her doctor. X-rays and MRI can demonstrate structural damage after an episode of knee locking.

  20. I was playing basketball two days ago I jumped up and landed on my leg fully extended locked and I felt inward pressure to my knee when I landed and imidiatly fell to ground and felt a lot of paint waited a few minutes and started to play again. My knee didn’t get swollen but have small pain when I extend leg and try to lock it in place. My question is what kind of damage can be cause to the knee when lading on it like that?

    • A knee injury suffered by landing on the foot with the knee fully extended can cause a number of different structures to be damaged, such as the ACL, one or both of the menisci, and the articular cartilage.

  21. Three days ago I was hit in the knee it hurt really bad at the moment I played the rest of the football game in discomfort. It swelled upright bellow the knee cap to the left. It hut for 2 days really bad but now it is better and doesn’t hurt much unless I’m sitting and not moving. What do you think

    • I can’t give you specific information. Generally if an athlete or active person improves within a few days, he or she can observe it and try to return to activities and see how the knee does.

  22. this rail or something hit my leg and on this specific side it hurts and when i poke on the right side of my knee some thing on the left side moves what should i do

  23. Hi Dr David,

    I had a fall a week ago. My weight is around 100kg and I’m standing on 176m tall. I fall on my left knee. I was scared that it got something to do with my bone. But on my referral letter to see orthopaedic stated my diagnosis with Contusion of Left Knee. Yes I did has bruised on my knee. I started with walking with crutches. And now I can walk without crutches. But my concern and fear is, I am still scared to bear weight on my left knee. As I felt loosen on my joint.I don’t feel pain. I am just scared if my knee able to bear my weight if I press and walk like normal. What is your opinion?

    I appreciate your assistance.

    Thank You

    • I can’t really say, but the orthopedic surgeon can tell you whether weight bearing is safe. Generally for simple walking, I don’t restrict a patient from bearing weight unless it causes significant pain or causes the knee to lock, catch or give way. But again, it depends on the nature of the injury.

  24. I feel on my left knee with all my weight back on January 17th and cant seem to get a straight answer of what is wrong and why its not getting better almost 10 months later. Ive had an xray and mri done and both showed normal. I’ve seen my normal doctor multiple times and no help, ive seen a knee orthopedic and they said I have runners knee and to do physical therapy and wear a knee brace both of which did not help the brace actually made it worse, the pain has gotten so bad that I went to the er because nothing is taking the pain away nor am I sleeping very well. The er doctor looked over both the xray and mri from January and saw nothing wrong and no runners knee either. He said that the pain I’m having sounds like a torn miniscus but that its boy since the mri was normal. My entire leg hurts it burns, stabbing pains, tearing pains, and sharp pains but no one can seem to help me. I feel like its going to have to get to where I cant walk on it at all before someone will help.

    • Jessica, that does sound frustrating. Meniscus tears almost always show up on an MRI. Without being involved, I don’t think I can give you too much information on particular injuries or their treatments. I hope you find an answer!

  25. Hey doc, I have some scary news. In two months I’m supposed to go out to Alberta to be a ski instructor and today I did something to my knee where it hurts to move up and down and I have pain when I fully outstretch it. I’m going to go see emerge right now, but I need to heal up in 2 months time. Please help me fulfill this goal! I’m very scared and I took a gap year so I could do this and now I’m injured!!!!! Please help me. Should I do stretching, ice, how often for both, nothing hurts when I poke anywhere around the injury which makes me even more scared.

    • I don’t know that I can help too much without knowing what the injury is. Your orthopedic surgeon can give you specific advice. Generally frequent ice and elevation to get the swelling of the knee down and working to regain full knee flexion and extension can be important in the first few days after a knee injury.

  26. hey the other day i hit a car fall off my bike and landed on my right knee. now left side of my right knee is swollen, now it hurt when i walk up the stair and down, and it hurt when i try to get up

  27. Hi Doc,last month playing softball I was taken out by my knee. I played the whole game in discomfort, but just thought it was badly bruised. It swelled up right away and had X-ray. Nothing was broke but still a month later I have a knot above my knee cap.I can walk on it, but it pops and I feel like there is air underneath my kneecap. I’m scheduled for an mri tomorrow my question is, will they be able to see if anything is torn or pulled (I have arthritis ) and if so will surgery be necessary??

    • Yes Lauren, an MRI can show injuries to the meniscus, tendons, cartilage, and ligaments in your knee to help your surgeon determine treatment options.

  28. My problem has now existed for about 3 months. I thought the pain would go away. Yes I one of those guys who try to tough things. Any how, my pain is located on my right knee, specifically on the inside left (top part inside left towards knee cap but not on the knee cap) I can not run, it is uncomfortable to walk an distance and I can balance or stand on the rich leg in a locked position without extreme pain and the knee giving way. I am headed in this week to have it looked at. Any initial thoughts or gut instinct thoughts?

    Cheers,
    Roger

    • I can’t say too much without examining you, but your orthopedic surgeon should be able to determine a cause. There are many structures on the medial side (inside) of the knee that can cause pain in that area – meniscus, MCL, hamstring tendons, patellar ligaments, plica, etc.

  29. wow…sorry for the typos in my question. Meant to say I ca not stand on my right knee in a locked position without extreme pain and the knee buckling.

    Cheers,
    roger

  30. I lost control of a scooter when rearly being hit by a car and my toe hit the asphalt and twisted my foot outward and could not dear weight.
    Two weeks later the two fractures below the knee cap and alignment of leg seems to be ok and I can bear weight and walk with the aid of crutches.
    The problem is there is still what seems like swelling or fluid just above my knee cap and I can’t bent my lower leg back to my butt however it is ok straight outward and 90-degrees downward sitting down (can’t bend lower leg farther than 90-degrees in sitting position)
    Can you let me know if this might just be swelling or a serious problem with a liagament

    Thanks,

    Morris MIller

    • If a person continues to have swelling and inability to fully extend or flex the knee, it is possible that he or she has suffered some kind of structural damage in the knee. An orthopedic surgeon can perform and exam and get x-rays to help in the diagnosis.

  31. I was on the back of a four wheeler. My boyfriend and I was going a little fast when we flipped. My leg was bent very awkwardly. My shown was thrown behind me. Now my knee hurts so bad I can barely walk on it. I can’t bend it at all. I also can’t fully extend it… please help!! I don’t have the money to go to the specialist

  32. I twisted knee when i was playing touch rugby over a year ago. I heard a pop sound. But it is not swollen right after that. After for like 6 hours it started to be swollen. I already see my doctor and he said nothing is wrong with my knee just put some ice on it at home. But then, i know there is something wrong with it, because i cant barely walk after a day i twisted my knee and when its recovered. I tried to play sports. But i cannot. If i take on a wrong steps, i can feel like i dislocate it and i started to fall. Do you have any idea how to get it back normal again? Like i can do my normal routine like hiking and jogging and i really want to get back to play rugby again. Pls help me on this

  33. My knee and calf were sore for 1 day with no explanation. Then I was hiking yesterday and going down hill on a stairway type path. Heard/felt a loud pop & instantly went down. Haven’t really been able to walk since. Slight swelling in the knee and no pain to the touch. I have full functionality of my foot, ankle and calf. I can put slight pressure on my knee if I keep my toes pointed outward as I walk with crutch. Im trying heating pad now after ice all night. I’m driving myself nuts with WebMD and such. Any thoughts?

    • I think ice can be helpful to decrease swelling after an acute knee injury. then a person can see how his or her knee does and if he or she has any of the signs I discussed in the post.

  34. Hi Dr. David!

    I love your site. I know you can’t tell me much without examining me, but I would just like a little input. I’m 28 and have no real history of knee injury with the exception of Osgood–Schlatter disease as an adolescent. Over the last 6 years I have experienced knee locking with simple twisting activities (twisting to get something from the back seat of car, twisting knee when simply plopping down on couch etc.). When this happens I have intense pain, and it is not possible to extend my knee (it feels like I will tear something if I attempt to extend, but I can’t actively extend even if I try). When this happens I manually pull my foot/ankle towards my thigh, my knee will audibly and visibly pop, and I can start to move my leg again (the knee pop is always painful and I will usually feel a nerve tingle). This only happens 1 or 2 times per year.

    I’m just wondering since this locking happens so sparingly if I should even bother to get it checked out. It doesn’t interfere with my daily activities. I’m even a marathon runner and my knee doesn’t bother me with long distance running. The only real knee complaint I have is regular cracking, which I have always assumed is normal, since it’s not associated with pain. Any thoughts?

    • I don’t ever think it is a bad idea to see an orthopedic surgeon if a person has locking or catching of the knee or sharp pain with twisting movements. generally crepitus – the grinding sensation under the kneecap that many people have – is normal and not a sign of anything worrisome.

  35. Hey, I was playing basketball yesterday on floorboards, I jumped up to get the ball and was pushed from behind. Well I pretty much just had my whole weight land on my knee. It is slightly swollen and quite sore to walk on. Is there anything bad or is it just bruising. Also what should I do to speed up the recovery as I want to get back into action. Btw I’m 14

    • I don’t know that there is anything I could tell you to speed up recovery without knowing the extent of the injury.The signs I mentioned in the post can help to determine if anything could have been damaged

  36. I injured my ankle months ago, around March or so and ever since my ankle has not heeled. I don’t know but I think that maybe it’s because of something with my knee. Sometimes my knee locks and I can’t move it until like a few seconds later. And Its also in the same leg. What do you think?

    • It could be. If a knee is locking, or getting stuck in a certain position where a patient cannot fully extend or flex it, then it can be worthwhile to see a doctor and find a possible cause.

  37. hi can u help me please?? i hurt my knee about 5 months ago while walking down a hill. Went to an otho doc and gave me a shot. Few months go by go to another othro do had mri and he said i tore a muscle in my knee lateral of the meniscous he gave me a knee brace, told me to stay off of it (not possible have a 2 yr old and right knee) then said to come back in 8 weeks. He said it shld heal within 2 weeks like i said been 5mos. My question is do i need a second opinion??? i keep hearing tht if it tears more its unfixable and eventually wld have to have a total knee replacement??

    • I honestly don’t know. I never think a patient getting a second opinion is a bad idea if they don’t feel comfortable with the diagnosis or treatment plan from the first doctor.

  38. I just recent started with Roller Derby. The first time I try to past a laps test ended with a pain in the outside upper part of my left knee. I figure out later streching help. But the knee sometimes swollen but goes down it used to lucked but some movement very seldom.very seldom as well If I strength it it hurts some no much really. But I am able to run with no pain and walk fine. Any suggestions

  39. I had a boating accident about 5 weeks ago had an MRI which showed a sprain with swelling. Do you know about how long that takes to heal?

      • Hi my name is Patricia on my rite knee it hurt so much that I can’t stand on it or walk on it it pops all the time and it tighs up from the back of my knee I was told 6years ago that I had fluid inside my knee and they were supposed to drain it out but they never did and now since then I’ve been hurting

  40. I had two knee surgeries acl in 1999 and MCL replaced in 2002 now that have atorn menicus of the radial cuff a baker cyst and chip knee cap ,also osteoarthritis . I tried orthovisc gel injections had to stop after two injections,my new reacting badly to it. Next is a cortisone shot . would it be to do a third knee surgery ????? I’m only 31

    • Deciding if surgery for a meniscus tear is warranted when a patient has coexisting osteoarthritis can be difficult. Your surgeon can help you decide if your symptoms seem to be coming mainly from a meniscus tear, for which arthroscopic surgery can be helpful, versus arthritis, for which it often doesn’t help much long term.

  41. Hi there,

    I did a workout last night with a lot of jumping around/pivoting/kicking/punching etc.

    I woke up this morning and my right knee was in agony when turning over in bed (left knee perfectly fine!) As I stood – the pain radiated from the outer left side to the back of the knee when extending my leg fully or bending upwards past a certain point (eg climbing into my husband’s Dodge 2500).

    I’m usually a fast walker and can jump up and walk anywhere (I’m only 34); but now when I stand, it takes a few moments for the pain to stop before I can carefully walk (hobble) with minimal pain. I can’t pivot or turn with that leg or else I’ll be on the ground (same goes with turning my foot of that leg and putting pressure on it, it hurts to turn my foot inwards even with no pressure)

    I don’t recall injuring myself during my workout, and my husband wants me to stop doing them (I can’t, I am 50 lbs overweight and need the activity as I have a very sedentary job). Do you think I would be okay to moderate the workouts (e.g stepping out instead of jumping etc)?

    I’m able to comfortably do squats (yay!)

    Any suggestions on my best treatment? Any exercises that might help me strengthen it back up again?

    Thank you!!

      • It is hard to say, honestly. Generally without a specific event, most athletes and athletic people can modify activities for a few days to see if the symptoms go away. If they don’t, then seeing a doctor or orthopedic surgeon can be helpful.

  42. My symptoms are none of the above. I have no knee pain in normal activities, however if I bend the left knee past 90 deg, I get pain on the medial inside area. The more I bend it, the more the pain. It had initially felt like a general wrenching pain somewhere in the center of the knee, however now it seems to be more toward the medial front. Your suggestions would be appreciated.

    • Meniscus tears can often cause one-sided joint line pain with full flexion of the knee. Osteoarthritis changes could do that as well, although the pain is often more diffuse through the knee.

  43. Thanks for the feedback. It actually seems to be gradually improving over the last couple of days as I flex it a few times a day, so perhaps it will resolve in time. It’s back to a more diffuse pain deep inside the joint, so maybe OA as you suggested.

  44. Hello sir,
    I will be really greatful if you help me out, please.
    I am an obese girl with sedentary lifestyle. I am 26 years old.

    Around 2 months before while exercising on cross-trainer my left knee started aching, and i stopped exercising immediately. It continued to ache for 2 days…it was a bearable pain. I was frightened and optec not to exercise for 1 week and later instead of choosing cross-trainer, i used treadmill to exercise. Normally i can brisk-walk on treadmill for 30 minutes but ….but this time within 10 minutes of walking my left knee started to ache again…now this time i was really very frightened and stopped exercising

    Thereafter , there was no pain, but while standing a very few incidences happened that made me feel that my left knee was locked…for a few seconds …where i just cannot move it and a slight pain occured for few minutes. I exprienced this around 5 times on various occassions.

    Today, i took a walk again, and within 15 minutes i felt that the movement of my left knee is not as swift as that of right one, and it was not normal…..while moving left leg i startec feeling two movements…one was my foot touching the ground i.e., of lower leg and later with a minute difficulty of upper leg moving forward……it was like as if my leg was broken into 2 parts.

    Is there anything serious, or am just too bothered. Is this normal. Should i see a doctor. Can there be some injury?

    • There could be an injury, especially if a person has a feeling of the knee giving way. An orthopaedic surgeon could help you figure out the cause of your symptoms.

  45. hello, i fell in my shower about 11 days ago.i remember pulling my leg to put in front of me since it was bent back. went to the ER and was told a knee sprain, wrapped with ace bandage, ice packs and was handed crutches (being 51 never had broken bones or sprains). i was told to follow up with my primary doctor and if needed an ortho. my knee looks normal again, some tightness in my calve muscles and when bending. i can now place my foot on the floor, i use the crutches as if i am skiing,i shuffle, i am so afraid to bare total weight on this leg. i been out of work for this and the type of work i do is being on my feet for over 8hrs a day. how can i get over this fear? just to be able to walk again and get back to work .thanks

    • Honestly I don’t know an easy answer. Seeing an orthopedic surgeon to determine a patient’s extent of damage can be a good idea after a traumatic knee injury.

  46. I’m a 15 year old and today when I was running flat out my knee just gave and buckled. I could feel a pop and I can not put any weight on said knee. The pain is centalized to just left of my left kneecap and any twisting or fast movements hurt. It hurt immediately but gave way to shock very quickly. I would like your opinon on this doctor.

  47. Hi
    I understand you do not give specific info. But I was wondering if I should see a doctor or just rest longer. I fell 8 days ago. A very big bruise and swelling occured immediately. I have rested up iced it elevated took anti inflammatories. I still have a big lump , I’m assuming its fluid as its soft. Would I have to get it drained or will it occur naturally.. it is still tender and sore to touch and walking for a long period.
    Thank you for your time

    • Generally large collections of fluid – either blood or joint fluid – resolve with rest, ice and anti-inflammatories. An orthopedic surgeon might help you figure out ways to get back to normal faster.

  48. Hi, excellent site and a lot helpful advice sought and given.

    Knees, the bain of my life over the last 6 months. First, Mr right knee shows signs of locking, crepitus for sure and pain just above and to the left middle. No apparent injury, but did observe bruising near the thigh / knee muscle connection in the early days. I am 42 and put it down to active sporting career, football now mainly.

    To top it all, my left knee has now reacted in the same way, similar difficulties walking upstairs and catching me when I least expect it.

    Any ideas what the cause may be and how would you recommend getting through this phase. Lying down an tensing my legs is sure way of bringing on the pain but my physio doesn’t seem there’s anything wrong them mechanically as far as ligament damage is concerned. I’m drinking plenty of fluids in case a hydration issue.

    Thanks in advance of a reply.

    • I really can’t give you speicific advice. Some of the issues you mention sound like they could be related to the patella (kneecap). Often strengthening programs can help a patient resolve patellofemoral pain.

  49. Hello, im an 18 year old male. My knees have both given me trouble for several years now, with my right knee being more severe. They pop, all the time, and never without pain. My right knee often seizes and has to be popped into motion again. Lately, I cannot straighten my knee without severe pain and a buckling sensation when I break the barrier my knee tries to lock at. I went to an orthopedic about it, and they refused to mri, only doing an xray. The xray showed my kneecaps were slightly dislocated but did not match with my symptoms nor pain level. Is there any chance you could shed some light on what it may be? Or if I should pursue an appointment?

    • I really can’t say without examining you. Abnormal tracking of the kneecap can certainly cause popping, although many other problems, like a meniscus tear, can as well. If a person’s pain is related to the kneecap, physical therapy can often resolve the pain and return the person to normal activity. Other problems often require and MRI to diagnose.

  50. It has now been 7 weeks since boating accident. I still have slight pain in knee. MRI showed minimal horizontal linear signal within the posterior horn of the medial meniscus. Do you know how long until that will heal completely and have no pain?

    • Meniscus tears generally don’t heal very often. If they go on to heal, or if a patient’s pain goes away spontaneously, I would think it could take weeks or months.

  51. Have Morton’s neuroma on left foot been wearing aircast. Four days later back of knee hurts bad. I can ride a stationery bike but cant get full range of motion when walking. Can bend leg also can straighten but with pain. Can pain be from awkwardness from aircast that caused pain in opposite leg? Thanks

  52. Hi Dr. Geier,

    About 4 weeks ago, I fell from sitting on a stool. Instead of falling back, I fell on my left knee, directly on my (medial femoral condyle). The first week all the pain was coming from the medial part. I have full flexion of my knee, but lack the ability of full extension. I can maybe only extend it to 30 degrees. Went to urgent care for x-ray, results were negative. Physician referred me to have an MRI done. After the injury, my knee never really swelled up. I just had a lot of pain in the medial part of knee. Any idea, of what injury this may be? Also, any chance my knee heels improperly and I stay walking with my knee bent forever?

    Thanks!!

    • It’s really hard to say without being able to examine you or see the MRI. Your doctor should be able to give you more specific information. I hope it turns out well!

  53. Hello. About a month ago, I went to the farm. I was putting chickens in crates and one was trying to get out of the crate so I tried catching it with my knee and it popped. It still hurts and feels sore when my leg extends…..any help?

  54. Hi,
    I know you can say exactly as you have not examined me, but a year ago now I was tackled to the ground quite hard by 2 larger males I’m only 53kgs, I’ve come down and straight away my left knee was in pain, I could still walk though, every now and then it seizes up and is so painful as I wait for my knee to pop/crack back into place, now the last week it has started swelling up and is so painful to even walk or pick things up, I can’t straighten my leg out as inside knee starts really hurting, and I can can’t turn my knee towards the right it starts hurting also, I thought I may of just sprained it or twisted it the wrong way but after a year its getting so much worse.

  55. Hi, I am an otherwise healthy 51 yr old woman who is going through the menopause. I have had a grumbling pain in my right hip for 3yrs which recently has got much worse causing me to limp a lot. About a month ago I started to get pain in my right knee and now I can’t straighten my right leg at all without pain in my knee joint. It’s painfull to walk long distances and also jars if I turn quickly or change direction when I’m walking. I’m reluctant to see my GP as she just says ” well you’re not getting any younger you know”. Should I be worried about this or soldier on?
    Kind Regards
    Amanda

    • I generally feel that people who can exercise, play sports or do their normal activities due to a musculoskeletal injury should see an orthopedic surgeon to determine the cause of the symptoms and find a treatment strategy.

  56. I have pain in my knee in the front inner knee when i bend it while bearing weight at the same time. I can bend my knee and lift it up no problem but I cant squat or go up stairs. I really feels like it will give out and the pain is worsening. I went to a physio and he said my inner thigh muscles are not developed enough so it is pulling my knee cap outwards and i have to strengthen my legs. I play volleyball and i have been doing small exercises and squats (cant anymore) but it is getting worse. I never injured it as far as I know and I recently gained 30 lbs in two months. What do you think it could be?

    • I can’t really say without examining you, as there are many causes of medial knee pain. You might see an orthopedic surgeon to get a diagnosis and discuss treatment options.

  57. Hi Dr David few days ago I sprain my ankle and after a week it’s better now but I’m starting have pain in my knee any ideas why ? Thank you

    • Sometimes an injury in one joint causes a patient to change his gait slightly and stresses other joints. I don’t know if that is occurring with you, but we see it frequently.

  58. I had a TKR 5 years ago. In January, I started working out and have lost 60 lbs. I don’t run or jump and never lift over 50 lbs of weights. I do some hiking, but only 2-3 miles at a time and don’t consider it strenuous. Last week, my replaced knee started bothering me a little and now, I can’t straighten it all the way without severe pain and every now and then when I step on it, I get severe shooting pain for just a second. There is no pain unless i try to straighten or bend beyone 90 degrees. It’s concerning to me and I wonder if you know what the problem could be or if you think it’s serious? It’s keeping me from working out; I can’t even ride the exercise bike.

    • It is hard to know without seeing you if there is scar tissue or a problem with the components or if there is nothing worrisome going on. You might see your surgeon and find out if you have a serious problem. I hope it works out!

  59. Not sure what I did to back of knee, no sudden trama or pop just started to hurt bad. It has been 12 days since start of pain back there. I went ER yesterday they performed ultrasound to rule out blood clot or Bakers cyst. Ultrasound came back negative. I can walk downstairs and up the stairs but i cant walk with full motion in general. I can bend and straighten my knee pretty much no problem. One of my friends says it could a meniscus tear :( would it possible to be able to walk up and down stairs and have a tear?

    Im saving now to get MRI, but no sure what to do in mean. I haven’t exercised in two weeks. Nervous to even ride a stationary bike or elliptical.
    Any advice would be apprecited

    • Pain in the back of the knee can come from a meniscus tear, although there can be other causes. Usually a patient has pain with twisting motions or deep squats, but pain with stairs and other impact can be present too.

  60. Hi, been reading some of the comments hoping to find my problem. Left leg (entire) feels like all the ligaments are pulling. If I turn my knee outward (as in sitting Indian style), I have shooting pain into the sole of my foot. Can straighten the knee but not bend it all the way, so sitting down I have to use caution. I don’t trust that I can walk without falling anymore. But am ok if I know it’s due to a knee injury, but wondering why it is affecting the foot so much, that is really painful when moving my leg. uggghhhh seeing the Orthro Surgeon the end of the week for the 1st visit. But any ideas?

    • Your orthopedic surgeon will be able to give you specific advice and help you determine if you have a knee injury as the cause of your symptoms or some back or neurologic issue.

  61. So 2 weeks ago, Today I was hit in the bottom, outer part of my knee by a hockey stick with extreme force. It swelled up, has bruised and took me a long while to be able to straighten it and bend it (but not fully). It is painful to walk on without limping and also when walking up and down stairs, especially when walking upstairs I can feel it about to click until it does, at least once whilst bringing with it a lot of pain. I can virtually straighten it but cannot stand on it without feeling pain. I went to the doctors just over 1 week ago and was diagnosed with just bad bruising and blood in the joint area, restricting movement. I was told to go back if I was still in pain the following week or so, and still feeling pain wondering whether I should go back. I don’t think it feels like a bruise and the visible bruising has nearly gone down. What re your views? Should I go back to doctors or does it just sound like a bruise? Thanks :)

  62. About 4 months ago I twisted my right knee while my foot stayed planted. I ignored the swelling and stiffness due to planning my daughter!s wedding. A week ago I saw my GP who had me do z-rays and then an MRI. A tear in the cartlidge was found. I won’t be seen by Ortho until January, how do I manage pain and protect my knee from further damage until I see the Ortho?

  63. I was playing a football game and a kid purposely steps on my knee and i didnt play after that and cant walk on it

  64. Hi, since running in July my left knee suddenly became very sore and swollen and has only gotten worse. Hurts primarily when getting up, standing, walking, sleeping (aches). I have seen a sports dr and had an X-ray. The X-ray showed a healthy knee so the suspicion is perhaps a meniscus tear and have an MRI scheduled (not until march unfortunately). I am in pain daily And find it hard walking on it, but movement and light exercise does help. Going to a sports chiropractor and he massages, stretches and tapes the knee in hopes of alleviating some of the swelling. That is his concern, is the fact that the swelling never seems to go down. By the end of the day the only way I can describe it is that my knee is full from front to back with cotton. Also going on 5 months with this and from I have read with exercise, supplements, proper stretches and physio meniscus tear should heal with 4-6 weeks.

  65. so in the recent 2-3 weeks i have been noticing that when i sit or squat or basicly bend my knee for a period of time and then straighten it that it sometimes pops sometimes not hurting when it pops but other times it feels as if someone just like punched me so also when i straighten it always hurts sometimes more than other times but it is usually worse as in it throbs and feels as if ive been punched on my kneecap and i sometimes have to sit right back down because it hurts to the point that i am almost in tears and i told my parents that when i straighten my leg and my lower bone on my kneecap and it gets to a certain place it hurts a lot and all they say is that i need to stretch more often but when i try the stretches it hurts a lot and they tell me that it will help but how can it hurting while stretching help it seems as if it should make it worse…… i need a proffessionals view … my parents wont let me go to the chiropracter to see if it is serious because they both dont want to “waist ” money as they said and that it would cost too much … another thing u should facter in is that i am a soccer player at the age of 13 and when i was younger i had a problem with my legs suddenly collapsing under me and me falling during p.e. class …….. could u please tell me what u think might be the problem … please … i am just tired of not knowing how to help it .. so if u could tell me what i think is wrong and if it might be serious i would appreciate it so super much

  66. so when ii sit down or squat or basicly bend my knees and then straighten them to a certain point then my whole kneecap has a stabbing pain almost like someone was shoving something hard up the bottom side of my kneecap and the pain stays as long as 1-5 minutes

    • I don’t know if this is your problem, so you might want to consult a doctor for specific advice. Patellofemoral pain can cause pain under the kneecap and throughout the knee with sitting with the knee bent for long periods of time. Popping or grinding under the kneecap is a common sensation people report as well.

  67. I have been to the doctor many times and have been in physical therapy for about 9 months and my knee still isn’t getting any better. They have told me that the ligament that holds my kneecap in place is loose but they can’t do surgery until I stop growing. Now sometimes I cant control it, my muscles will start contracting and I can’t stop it. Also, it pops and cracks a lot I can hear it as well as my friends and some of the people around me. The doctor gave me pain killers awhile ago but they don’t work. And most of the time I can’t walk very well because of the popping, cracking, and my kneecap is slid out. Should I go back to the doctor and if so what do I tell him?

    • Surgery for patellar instability can be tricky for patients who have open growth plates. There are surgical options in young patients, but there is concern of higher failure rates. Physical therapy, braces and activity modification are generally the other options we try.

  68. My knee has been bothering me since I was in an accident back in september. I sprained my knee & wore a knee wrap for a week or so. I was able to gradually start running again a week afterwards but my knee would swell up afterwards. Then that stopped for a while and I’d have pain around the kneecap like i did after the accident. And I’m still having trouble with my knee it doesnt swell but it hurts on the inside of my knee along the right side. It sometimes causes my foot to go numb & hv a little pain along the right side of it. I took asprin but it only helped a little. Running doesnt make it hurt any worse all the time. But every so often my knee locks on me & I have to physically unlock it & it’ll give out sometimes also. Right now the pains at a 3, 3 1/2. I wouldve thought the sprain wouldve been healed by now & it should be. So I think it may have been overlooked. What could it be? I have no trouble walking or running my foot just goes totally numb for a few min. Should I go back to the doctor?

    • Paris, it is really hard to say, but visiting your orthopaedic surgeon might be worthwhile to figure out why your knee is locking.

  69. Hi, I was playing softball a few weeks ago and slid into second base on my left knee. I had hit it hard on the clay and scraped it up and from the impact it was really sore. I played the rest of the game with my adrenaline helping me thru the game. After words when I got home it was just a little sore. Didn’t hurt to bend it or move it. I got in to bed the next day on that left knee and felt a sharp pain in it. Hard to bare. I felt around on my knee and couldn’t find the spot that it hurt. I did notice that the scabbed area was numb. I couldn’t feel my daughter pushing on my scab or in that area. Now a couple weeks have passed the scab is gone and the area is still numb and I still get a jolt of pain if I get on that one knee just right. Is this a major problem that can be permanent as far as the jolting pain or the numb feeling in my kneecap? Have I waited to long? Also, I am Flooring Contractor and I use my knees everyday and i haven’t felt the pain when on both knees… Any help would be greatly appreciated. Thank you…

    • Patrick, I really cannot give you a specific answer to your question, as I haven’t seen you as a patient or examined you or seen any radiographic studies. I doubt you have waited too long, so an orthopedic surgeon should be able to help you. I haven’t seen nerve injuries landing on the knee myself, so I’m not sure I can speculate as to the cause of the numbness. Hopefully the surgeon can help you after he examines your knee.

  70. When I was playing basketball I came down in a weird position. When I came down my knee was twisted and I felt my knee pop when I fell. The swelling went away and I can extend my leg straight out. Sometimes when I twist my legs again I feel my knee pop again and it hurts a lot and I can’t walk. Then when I extend it out straight out, I hear another pop and I can walk again. Do you know what this is?

    • There are many reasons for knee popping, ranging from tracking issues with the patella to cartilage damage to meniscus tear to popping for normal reasons.

  71. Hi, about 2 years ago i tore a ligament in my knee and let it heal on its own then when it was healed i ran and my knee poped out then went back in again and it hurt also till this day it still does that and i cant ran and after that i went to the doctor and said nothing was wrong with it

  72. I was moving a very heavy piece of furniture by myself and when i bent down using my legs and tried to lift myself back up my knee made a popping noise followed by intense pain and now i cant bend it further than 30ish degrees without a feeling of pressure on the kneecap. Also i cannot walk on it without similar feelings. I am scared to go to the hospital. I read 30+ websites and i have a guess that it may be a “meniscus tear”. I just want your opinion on the matter to find out if its worth getting it looked at.

    • I think if someone has a pain or other symptom that keeps him from doing what he wants to do, it can be a good idea to get it checked out.

  73. Hi. I’m trying to figure out what kind of damage I have done to BOTH of my knees simultaneously. In martial arts they can spring to their feet from their back by bringing legs over chest and using that momentum to propel them to their fit. For whatever reason I too thought I could do this. I did not get up off the ground high enough and smashed both knees on the concrete then landed hard with them bent behind me. I feel pain in the back if my knee in the inside. I can’t hardly walk its excrutiating. Bi lateral movements are so painful I just fall instantly. There isn’t much of any swelling. This happened last night. What did I do!?

  74. Do I need to be examined? I had to crawl to get to the bathroom. I think my left knee took most of the force it’s worse than the right. I do not remember hearing a pop but then again it hurt so much I was seeing stars. I almost went to the hospital this morning but I can’t really afford it

    • I think that if a person has an injury that causes pain or other symptoms that are not resolving and limit his or her ability to do certain desired activities, it can be a good idea to see a doctor and find a cause.

  75. I sprained my knee and there’s a big knott just under my knee cap they gave me a stabilizer and crutches but it seems to be getting worse I was cheering I heard a,pop my knee locked and it hurts do you know what’s wrong with me

  76. I played soccer on a hard surface with hard moulded shoe. I did too much running but had no injury that day. The night of the following day was terrible. I can pull my leg while lieing flat but upto a certain point. At that point the pain is awfull. Past that point is easier again. Sliding back to the original position is easy all the way, but only if I slide it. This means I cannot return it to its original position while suspending the foot on air. I did some cold press and a hot press today. The pain is not going away. What happen to my knee.

  77. Hi Dr. Geier. Two years ago I was running in a XC race and I tripped down a hill and hit my knee on a rock. I did not see a doctor nor have I seen one because my mom said they were growing pains. Since then my knee has not been the same. My other knee also hurts, probably worse than the other one, almost all the time. I can’t sit or stand for long periods of time without my knees feeling like they’re about to buckle. What might this be, and is it serious enough to see a doctor about?

    • I think it is always a good idea to see a doctor or orthopaedic surgeon if symptoms are not improving. Patellofemoral pain can occasionally present with difficulty sitting for long periods of time. More serious injuries can cause pain as well.

  78. I to hurt my knee in cheer and im in tremendous pain so I understand Alexa I just iced mine a little then started using crutches but it got worse so I found this website so just hang in there girl

  79. Beginning of this year,I go for sports recently.My knee started to pain.Few days later my knee doesn’t pain anymore.I go for holiday last week and I walk there mostly.When I come back my knee is pain again.It will pain sometime when the time I wanted to sit and stand.It will also pain when I take something heavy.I would like to know what is wrong with my knee.

  80. I was playing football and was pushed whilst my foot (boots) were in the ground and I went over sideways and heard a clicking noise (like if you cracked your knuckles ) i was in pain and didn’t see a doctor or anything as I thought it may go In time. However when I do things for example out pressure on my knee if I go on my hands and knees it causes discomfort and a little bit of pain in a certain spot. Do you have any idea what it is or some advice?

  81. Hi
    I feel pain from the back of my right knee (middle) to
    the front of it when I try to squat, or if I squat for more than 5sec it goes numb or I get a tingly feeling. It started back in spring of 2013, track season of my senior year when a soccer play chose to run in front of me when we where doing running workouts my knee hit his, and I slid a bit, it hurt at times for about 2-3 weeks, then the pain went way, but know that I don’t run, I’m starting to feel the same pain.
    Did I injury a nerve or a tendon/ligament?

  82. Background: Tore ACL in July 2012. Surgery in January 2013, ended up being partially torn rather than the MRI-shown full rupture. Surgeon cleaned up knee, injected PRP in ACL, and expected full recovery. Did PT for 3 months, slowly returned to soccer & basketball w/ brace for 12 months, and removed after 12 months.

    Fast Forward: “Tweaked” knee 2 weeks ago. Minor swelling & pain, resolved in 2-3 days, had PT friend do a few tests (and her boss too) and inconclusive, but most likely no ACL rupture since Anterior Drawer & Lachman’s were negative-ish (still lil extra laxity in ACL). Possible meniscal tear from clicking inside knee, but no pain now (14 days later).

    I’m not 100% certain my knee is a-okay. What should I be looking for besides pain and locking/buckling? Hopefully it’s good to go w/ my Breg Fusion brace for 4-5 weeks and some self-PT and stretching/strengthening, but is there a possibility it’s ruptured without other symptoms? I am worried about playing at ex-Division 1 college soccer player level, which is my current league (since I played back in college). Besides an MRI, any tips for symptoms or “what to look/feel for” is greatly appreciated!

    Thanks in advance and happy new year!

    • I can’t really say, but I understand your concern. Generally we look for signs that a partial tear is not providing enough stability to the knee, so we look for the knee buckling or giving way with activity.

  83. A couple of days ago I went up for a layup and landed wrong on my knee. I didn’t hear a pop and is only just a little swollen, but I can’t straighten it. It feels like something is preventing it from straightening. It also hurts when I try stretching it.

  84. I was running and tripped, my knee hit the asphalt hard. There was some swelling and scratches with bruising. I used RICE and let it be. This was 2 months ago. Ever since it hurts if I bend it and then try to straighten it out. I can’t put any pressure on my knees, such as kneeling. For everyday use I’m pretty ok. But I do jujitsu and the pain is unbearable. I don’t know what to do.

  85. I have an acl tear and need to have surgery last night while walking my knee gave I had to have help getting up and assistance to go sit down. Now my knee is swollen and in pain even when sitting I don’t know what should be my next move is i can hardly walk

    • Generally surgery restores stability to the knee. Before that point, some patients benefit from using crutches or a brace, although it can be important to keep the knee from getting stiff.

  86. I felt a pop and pain on the back of knee while getting off a motorcycle today. I had a MCL injury 2 months back. Have i reinjured it?

  87. I am a “runner.” I typically run 25-35 miles a week, just under 8 mile pace. I never have any knee pain or trouble in the last 10 or so years since high school. (I had some knee injuries in high school sports, but haven’t had any since wrapping up that “career.”) About a week and a half ago, I started having some pretty severe pain after completing a P90x workout. I did not hurt it during the workout, perse, but had the pain afterwards. The pain is as follows: Localized pain under my left knee’s kneecap on the medial side. (I hope I’m using the correct terminology there.) It also feels painful “inside” of my knee in that same area. I tried running the next day, and it warmed up fine, so I went five miles (looking back, that was a poor choice, but I did not have pain while running those five miles). Afterwards, however, the pain was pretty significant. Since then, I’ve not been able to run, and so haven’t tried. I have been riding the bike 8-10 miles per day and rowing. I can do both activities with no pain. I’ve been icing as much as possible as a full time teacher and mother of two toddlers is able. My pain is now more “soreness” throughout the day, although I’m sure I would have more acute pain if I tried running again. I feel the pain when I fully extend my knee, whether that be in a sitting position, laying position, or even when landing on a fully extended knee while walking.

    I’ve already had a meniscus repair, about fifteen years ago in high school, and I’m really hoping I don’t have any ligament or meniscus issues. I wondered about runner’s knee, but after not running for a week and not seeing any real improvement, I’m concerned it might be something more serious. Any thoughts?

    I am running my third half marathon in may, and hopefully my first marathon in Sept. I’m really bummed about what this situation may do to those plans. I know there are far worse things in life than a knee injury, but running is my favorite hobby. Thanks!!

    • I can’t really tell. Meniscal tear, patellofemoral pain and more could be in a differential diagnosis. Given those symptoms, it might be a good idea to see an orthopaedic surgeon to find the cause and plan treatment.

  88. Hi i am a.19year old medical assistant student a week ago i was standing in the front of my class begining to do a check off and suddenly my knee gave out twisted and poped a few times i had an an x-ray done and was told that nothing was broke or out of place but there was a lot of fluid on my knee and if it did not get better in two weeks to get an MRI done sinve then i can now walk on it with the knee emobilizer on and can bend it to a certain point if i bend it to far i feel a terrible pain on the right posterior side im really worried about what could be wrong and stressing about it getting better i know with out an exsam u cant diagnose but i would like to know y something like this happens and what the chances are of it getting better

  89. Hi, about three months ago I hurt my knee. There was a painful pop followed by swelling and pain while walking. My doctor never had any tests done, she just said to rest it. Now here I am three months later with continuous pain every day. It sometimes gets to the point where I want to cry. It hurts when I walk too much, or sit for longer than an hour. And also I cannot fully extend my leg without some pain alongside. My doctor had an X-ray done and nothing came up… Now she has me on rest again…… I need another doctor -_-

  90. I have twisted my knee twice and it has popped with me just dropping to the ground, very painful. I am going to see a Dr in a few weeks time but yesterday jogged 3 steps and my knee gave in with terrible pop and pain. I am able to straighten my leg and it just aches, but I cannot bend my knee without terrible pain. Not sure if I should go back to Dr on Monday and not wait to see the orthopaedic Dr. Can you give any advice?

    • An orthopaedic surgeon can help a patient determine if structural damage like a meniscal tear is present when he or she has pain with full flexion.

  91. I have pain in my knee that seems like it may be connected to ITB, what sort of exercises/treatment is done for an ITB issue?

    • Typically physical therapy is very helpful for IT band syndrome. Sometimes stretching exercises and the use of a foam roller work, but physical therapy seems to help people return to activities quickly.

  92. I have prior surgery and problems with my left knee, but recently i fell at work and hit my knee on the steps then later that same day i twisted my knee and it gave out on me with a sharp pain. Since that day my knee is more swollen then usual and the pain level is higher than usual. My knee gives out more and when i straighen my leg al the way out i feel a sharp pain in the back of my knee and front of knee under my knee cap. When i feel this pain my knee immediately gives out. The first two days afer the incident i could not bare weight on the knee. I have had an xray and the results were normal. Is it possible that i tore something maybe my menisus? It has only been a full week today since the incident.

  93. Hi, about a month ago as I was sitting Indian style on my soft bed, I slightly twisted my knee as I stood to get off my bed. It felt as though I dislocated my knee at the time as it felt out of place and would not “pop back in”. It was extremely painful as I tried to straighten my leg. I ended up in the E.R. because I could not walk and was told after x-rays it was in place but I had a lot of fluid that had accumulated around the knee. Anyway, fast forward to today and my knee has since healed except I cannot fully beND it like I would with my good knee. It feels almost like it would pop out if I bent it too far (heel to butt). Just slightly painful, tight with pressure on top of my knee. Could this be a meniscus tear or healing sprain still, fluid accumulation preventing the bend or???

    • Any number of problems can prevent full knee flexion. Certainly a large amount of swelling within the knee joint could make it difficult for a patient to bend his knee.

  94. I few moths ago I had a fall slipped on spilt coke on shopping center floor I’m over wait and fell very hard my knee came up in a bruise but I couldent lean on my knee for weeks it killed me I hot the right side of my knee it was sore for afew monthes then I started doing aqua arobics and the my knee went on me it all swelled up I couldent walk on it I went and had X-ray and they say my patella is out to the left and a have foren body’s in my knee the pain is getting Worce and Worce I’m waiting to get into dr and my knee hurts when ever u move it what could it be do u think could the fall monthes earlier have done anything

  95. One month ago, I twisted my knee while skiing. I can walk and straighten my knee, but it still hurts to bend it all the way. When I play tennis, it starts to hurt after a while and I can’t really jump. Is this just a minor sprain? And how can I regain full motion of my knee?

    • It really depends on what is causing the pain and limited motion. Those symptoms could be caused from a patient having a minor injury, or they could represent a more serious injury, like a meniscus tear. You might consider seeing an orthopaedic surgeon to find the diagnosis.

  96. I fell off a ladder the other day at work and landed on my left foot with all my weight as soon as I landed I heard a pop and my leg buckled and I was on the floor in extreme pain for about 5 minutes I had to push threw the pain and get back to work or get fired I have pain in this knee and around it when I bend it or kneel it hurts to run and even walk sometimes it happened about three weeks ago but I can not afford to lose my job if I have to get surgery is there any way I can get rid of the pain and heel my knee without surgery

    • I really don’t know. It’s impossible to give you an answer without knowing what the injury is. You might consider being an orthopaedic surgeon to at least get a diagnosis and plan treatment.

  97. sir, i have knee problem that my knee cant bear weight and i fall down,
    if i jump also problems happen that i feel that my knee is going to be break, feel very hard pain and fall down
    tell me what kind of problem is that.
    what should i do
    thanks

    • People with those symptoms – pain, instability – could have any number of injuries, so you might consider seeing an orthopaedic surgeon.

  98. hey, the past Tuesday, my pe class went to a park and i jumped over a stream and my knee locked into place and i heard a really loud pop. I can’t put any weight on it and it can only bend so far, I tried straightening it but the pain went through my whole leg. Now my whole leg is swollen, what do you think of this whole situation?

    • I generally recommend that people see a doctor is they injure the knee and it locks in place. Often a meniscus tear can cause the knee to lock. I can’t say if that is the case in your situation, so you might consider seeing your doctor or an orthopaedic surgeon.

  99. Hi there,
    I fell yesterday while ice skating; my knee became bent into a very unnatural position.
    I did experiece much pain on the onset, but this morning I woke up with some discomfort on the medial side of my left knee. I feel no pain while still, but when I walk there is some minor discomfort and pain. There’s no swelling. Should i consult a doctor?

    • Blows to the lateral (outside) side of a person’s knee can injure the structures on the medial (inside) side of the knee. I can’t say if that happened to you.

  100. i am 20 years old now.one and half year back i met bike accident.my right knee was hit by high load.immediately below the knee part was swelled because of blood cloth.and it is removed by doctor.but nerve also damaged at that time.unable to put my right foot on earth.while touching ground, fingers can able to put on earth but not heel part of foot.it was of certain height.unable to come down.i consulted neurologist.he said that nerve compressed and shortend.
    i lost my foot movement. neurologist treated me 20 days with some costly injections and physio therepay.now i am able to walk.
    1.but i m unable to fold my leg completely.
    2.while in speed walking and running my left leg feeling pain.my doubt is,even my right leg cured it is only up to stand nd little walk.it is not taking weight of body.weight of body more balanced by left leg only.thats why it pains while running.
    3.i am not feeling my right leg as before.
    what should i do ?
    plz tell me…?

    • I can’t give you medical advice without being involved in your care. You might see an orthopaedic surgeon and determine a diagnosis and treatment plan.

  101. I was doing light duty house work, sweeping, moping, kneeling. I stopped because my back and hips were spas ing. Later, my right knee started hurting at top left side above knee. Eventually, the pain radiated up to the top of my leg and even my foot hurt. I took pain relievers every four hours and the pain would subside, but started reoccurring about every 3 1/2 hours. This lasted for one week. The night before I went to dr., I had been resting. Got ip for a short period of time and sat for a few hours. When I went to get up, I could not stand. I could not walk. The pain was so severe that I had cried and had to have help and hop in left leg to get to bed. I had been icing leg, wearing brace and seeing chiropractor. He said it was my back and knee. I would have beat everything I have that I had injured my knee. The next day, I had an appointment with my GP. My knee did not hurt (little tender). She stated by exam that I had some fluid built up and suggested an mri. It has been two days and my severe knee pain has not returned. I have never had pain like that in my knee and am happy, but amazed that it literally was so severe that I had to take pain meds every four hours and cried many times due to the severity of the pain. I know pain. I have fibro, lupus, and arthritis. I am scheduled for an Mir tomorrow. I don’t know if I should cancel the Mri or go ahead and have it. It is if no cost to me. My husband’s employer has a deal worked out for imaging. Just don’t want to waste their money or time if not necessary.

    • I wish I could give you more specific advice. Generally we perform MRIs based on specific findings on the physical exam and from information in the history.

  102. I hurt my knee 3 days ago when I was ice skating. It was loud so I don’t know if there was a pop or not. It has been hurting and I don’t know what it is . Here are the symptoms:

    -I can not walk on it

    – I can not bend it properly

    – when I touch it with even just a light poke it hurts

    Please note it has not been swelling. If you have any suggesting on if I should get a brace or not or any type of pain relievers there are for me to take please let me know. Thank you!

    • I can’t recommend any of that without knowing what the injury was. With those kinds of symptoms, you might consider seeing an orthopaedic surgeon to figure out what you have done.

  103. Respected Sir
    My age is 23.I apply for police so for that I running fast 3 to 4 days.After this I not practice of running.Now I can not walk I am very young but when I walk I feel a lot of pain in joints.So please suggest me advice.
    Regards

  104. Hi I realize you cannot diagnose but I am not sure whether to go to the doctor or not. I fell on the sidewalk onto my knee about 10 days ago. My leg is still quite badly bruised but my knee moves fine, doesn’t hurt much to walk, however I cannot kneel at all – I can’t put any weight on it at all. I can bend it in all directions with no weight, that’s fine but if I touch underneath the kneecap on the outside, it’s very painful. I’m wondering if it’s just bruising and whether it is okay to leave it a week or so to see, or if I might be doing more damage by not going to see the doctor now. If you have any thoughts they are much appreciated. Thank you.

    • I really can’t say. Generally seeing a doctor to get a diagnosis can help people determine if they are at risk for doing further damage, especially if they cannot bear weight. Having said that, many people often wait to see if symptoms resolve on their own. Good luck rebecca!

  105. Hello,
    Thanks for your article.
    I play a lot of basketball and because I sometimes feel an uncomfortable feeling when running on my right knee, I started playing with a knee brace and it doesn’t bother me.

    I have noticed that I can’t extend my knee fully without pushing it up with my hands or turning my leg a bit then getting it up.

    What kind of doctor should I see for something like this?

    Thanks

  106. Hi Dr., I am 64 year old male who went bowling about two weeks ago, I used a 14lb ball and tried to throw the damn thing too hard … i had sore elbow but I iced it and that went away. but one frame I felt something like stretch, with a little discomfort, had a little trouble going down stairs for day or two, then felt better, now is aching along with aching hip and calf..no swelling and I rode bicycle yesterday around block. Maybe I did a slight LCL sprain or stretch?? please ?

    • That type of mechanism can cause all kinds of injuries and pain without structural damage. You might see an orthopaedic surgeon if it isn’t improving.

      • Thanks so much Dr. I guess I dodged a bullet, because I walked to warm up and did Iliotibial band stretch and quad stretch and it feels better.. So anyone who is bowling and has not done so for years, don’t use a 14 lb ball and try to throw it real hard , and if you feel a “stretch” like “tweak” on outside of knee, you might not have done bad damage, maybe this will help someone who has done a similar thing. I will use a lighter ball, warm up and stretch before bowling and throw not quite so hard. thanks again.

  107. Hi.I sat down on my couch and pulled my legs up. I got a sharp pain in my right knee. I went to straighten it out and it popped real loud. It is swollen now. I have pain all over my leg and my foot keeps tingling. I have iced it, elvated it and took ibuprofen. Its still hurting…

  108. I have had ongoing knee issues for years. I have had an arthroscopy with lateral release in 2002, another arthroscopy in 2004 and in 2004 ultimately had a patellar realignment. Just recently I have begun to have issues straightening my knee when I stand up. Even after stretching I cannot fully extend my knee. I do not recall an injury taking place. When I stand it locks and I have pain on the lateral side of the knee joint. I was told back in 2002 that he would be surprised if my knees made it until I was 40. I am now 35. Could this be the joint deteriorating or a possible lateral meniscus tear? This knee has been my source of support through two ankle reconstructions when I was NWB and I’m afraid all of that extra stress may have done it in.

  109. Hello,
    There is something wrong with my knee. I am in doubt about how serious it is.
    I have had it for about 8 months.
    I can bend my knees, but my left knee doesn’t bend in completely without something inside it making a click sound. -The feeling of something clicking back into place.
    If I just try to bend it in completely it hurts very much and it feels like that thing, that has not clicked into place yet, is being stretched (on the front side of my knee, on the right side of the kneecap)so much, as though it isn’t long enough for my knee to bend completely.

    So it feels like a tendon going over on the right side of the knee cap, that has somehow come to position itself over some kind of bump, or goes around something else and is therefor stretched to its maximum when the knee is bend.

    Someone has told me that it could also be something in the joint tissue which might be damaged. I can’t tell what is more true and i don’t know if I should rest until it gets better or train it too keep it strong?

    Since i first felt the injury and before,i have been training intensively. I do lots or running, i do big jumps and drops every week and I really put a lot of pressure on my knee as often as i can with all kinds of varied strength and mobility training. That might be really stupid, but the reason i have kept up the training is that, as I said, when the thing has clicked into place it bends just fine. If do a proper warm-up i have no problems with my knee as long as I keep warm.
    Right after training when I start to cool down, it gets worse and I have to be really careful. When it is like this I can only bend my knee if I keep all the muscles around the knee completely tensed all the way down. When i keep them tensed from straight leg position, that thing is not able position itself in the wrong place and I can go all the way down into my asian squat.

    So what do you think? Should I stop training and see a physiotherapist right away, so I don’t destroy my knee? Or is it important that I train and keep the knee strong and flexible?

    I hope you can give me an idea of what goes on inside my knee! Thank you!

    • I can’t give you much information, but I never think it is a bad idea to see an orthopaedic surgeon or physical therapist to learn the diagnosis and plan treatment.

  110. Hi – I twisted my knee, it has pain and swelling was not able to bend or fully extend the knee. Had an MRI, as per two expert DRs. one denied any tear the other said it is a very minor menscus tear. However, it has been 3 week, still had some amount of swelling, pain not gone 100% but still cannot fully extend the knee. I can walk, with weight, or go up and down stairs with minor pain in knee. I would like to know why still I’m not able to straighten my knee fully.

    • I can’t say in your case specifically. Sometimes full extension can be difficult if there is a structural block to motion, like a loose body or a meniscus tear blocking the knee. Often a patient may struggle to regain extension if he or she has been keeping it bent. Pain and swelling can limit motion as well.

  111. Hello,
    I recently found out I sprained my mensicus to the point where it almost tore. My doctor said I didn’t need physical therapy, just rest. How long will the injury take to fully recover? And do you recommend any type of stretching or exercises? Thank you.

    • I can’t say I have heard of a sprained meniscus, so I’d defer to your doctor. Generally PT can be helpful for many knee injuries.

  112. So I’m 13 and I can barely fully extend my leg. Once it is extended it does not hurt, but whem I walk i limp and don’t extend it. Yesterday I ran in gym a bit and maybe hit my knee but cannot be sure. But I woke up this morning and cannot extend fully. I play basketball and have had knee problems before that have seem to have gone away. I am very worried because baseball is coming up and it is a big year. I have read stuff about surgery which I am terrified of. Any help would be great thanks

    • I cannot give you specific medical advice without seeing you and examining you. If you or your parents are concerned, you might consider seeing an orthopaedic surgeon.

  113. Hello,
    I recently 3 months ago started a fairly intense workout routine consisting of 5-6 times a week, 30-45 mins of treadmill or elliptical at a running pace, followed by 1 hour of various body movement exercises (lunges, planks, squats etc. all body weight cardio), then 30 minutes of weight lifting). Gradually over the past month I have noticed first twinges, and now sharp discomfort/pain in my left knee only. This only occurs when the knee is bent greater than 90 degrees and weight/pressure is being placed downward on it. The pain feels to be around the front kneecap area. I have not seen any swelling afterwards. Does this sound like an common and easily diagnosed problem? Should I be just avoiding the exercises that cause the pain or all of the ones that involve the knee? Could this go away/heal itself or does it sound like a more serious injury that needs medical attention? Thank You!

    • I rarely discourage anyone from seeing a doctor if their symptoms limit the ability to play or exercise to the level they desire. Pain under the kneecap often resolves without surgery for many patients, so some people do well with rest or activity modification. An orthopaedic surgeon could give a diagnosis and help design a treatment plan, though.

  114. I ran full speed and banged in a poll a metal poll. I didn’t get a lot off possum dud a checkup and had a turn meniscus so I’d you get hurt get an x ray even it didn’t hurt

  115. Hi there; a couple of days ago a fell walking to work. My right foot got caught in a pothole, my right ankle twisted, and I fell with all my weight on my left knee. At first all that bothered me was the skin because I got a nasty scrape on the knee. However, yesterday the actual knee started hurting and continued to get worse throughout the day. Today at work I couldn’t decide whether to keep my knee bent or straight because either way hurt, and moving from one to the other hurt. I can walk fine, but stairs cause pain, especially descending. The MOST painful thing is getting in and out of my car, and going from a standing to sitting position and vice versa. If I turn my foot at all to the left or right, it causes intense pain in the knee. Is this something I should see a doctor for, or wait it out?

    • oh, also, my knees have always made loud cracking sounds when I bend down, so I’m used to that – but the left knee has started making a different sound, not the usual loud crack but a quieter sort of ‘snap,’ and I feel it when I walk

  116. My knee got smashed on the ice after I tripped & went flying landing flat on my front side. The out side of my knee was grazed & slightly bleeding, I was in pain thinking I smashed my knee to smitherenes for 10 minutes, then pain dissapeared & I continued skating normally for 2 more hours. A few days to a week later I note I could not, an now 1 month later still cannot kneel. It’s a pin pointed sharp (like loose glass) pain on the patella toward the outside where I landed & something that feels like a ligament is moving about. The other knee has nothing moving so I know this is not right. No pain at any other time. Will this heal?

  117. Hello doctor, I have a question for you. I don’t know whats wrong with my knee but i buckle it a couple times already but after 1 week or 2 i recover from it. but when i play soccer and i put A lot of pressure on that same knee i feel iT buckle again. But im recovering from it again just by icing it and knee braces. i just wanna you to give me some idea to what is wrong with my knee. I don’t know if i tore my ligament or not. And i haven’t get it check out yet.

    • You would have to see a doctor to determine if you injured a ligament, but buckling or giving way could signify such an injury.

  118. Hi,
    I sustained an injury during rugby training 2 months ago, I twisted my knee and then couldn’t straighten it again and it felt like the fibular bone had slipped. I went to a and e with my bent knee and the doctor said it was probably a torn cartilage and he needed me to straighten it to go any further. So on gas and air (and with a lot of shouting) he started to pull it straight, it and a loud popping noise and the inside of my knee ‘jumped’ and the pain went and I could move it again. I assumed it had been dislocated and had now gone back in so I left a and e.
    2 months later as I was turning in bed the same injury occurred and I ended up in a and e again, the nurse again helped me pop it back in. However when the doctor came in after he insisted that this type of knee dislocation only happens ‘every once in a blue moon’ so it couldn’t possibly be dislocated, he thinks it is a flap of damaged cartilage flapping back and forth which is locking my knee. I also explained to him that I am incredibly hypermobile so asked if that would have any effect, however he did say I had a very stable knee.
    I am going to get a camera put in my knee and an mri, but wondered if you had any insight?
    thanks

    • I don’t, but an MRI should identify structural damage that could cause a patient to have those kind of symptoms.

      • Hey Dr,

        I was playing basketball last night in a league and I had a pretty hard headed on collision with a player from the other team trying to draw a foul and fell awkwardly on my knee. I Eason some instant pain limping but as I walked it off it got manageable. I finished the game, but now my knee is still hurting. I can do all the things in the 7 steps and have very specific sharp pain in one part of my knee. You think it’s anything serious?

  119. I hurt my knee yesterday night playing soccer. The pain was moderately high at the beginning and I could not stand up. There was no popping sound. After about 4 minutes the pain subsided immensely and I got up and walked with a limp to my car. I took alive and iced it before bed. I was able to shower and get ready for bed on my own, of course in some pain. I woke up with no swelling or discoloring of any time. I can fully extend my knee. I can bend my knee and bending it does not hurt any more than keeping it still. MY knee looks completely normal and has the entire time since the injury. My knee is in very slight pain (level 1) when sitting. I can put weight on it, and I can walk around slowly with managebale discomfort. I can stand on one leg on the knee that I hurt. It does not hurt in one area. It generally feels like my knee is sore and weak, but not specifically painful.

    I am very hopeful that this is not something extremely serious and I’m going to give it a few days. What are your initial thoughts? Also if I walk around slowly with some discomfort, can I make things worse? Should I try to stay off it a few days? Thanks!!! Rebecca

    • I really can’t say without examining your knee and looking at any studies. Generally the possibility of doing harm with continued activity depends on what the injury is. Giving it a few days to rest and see if symptoms resolve can be helpful for many people.

  120. Hi I haven’t fallen or done anything to my knee but today I bent down to my son and had a really sharp pain in one spot left side of knee on left knee it really painfull and can’t bend my knee without loads of pain

  121. Hi
    i fell down stairs 8 weeks ago my knee swelled up and was bruised , since then i have had periods where my knee i have had sharp pains and my knee has give way.
    THis is on off but my knee is making a loud clicking noise when extending my leg out fro a bent position any advice?

    • I really can’t say much more than it might be a good idea to see your doctor or orthopaedic surgeon. Good luck!

  122. I’ve been to the doctors for an xray and mri but they said nothing is wrong. I know something is wrong because I cannot straighten my knee. An incident happened this morning when I was walking and I accidentally straightened it. My knee made all sorts of popping then went back to being bent and began to hurt even more. when it first started was 2 weeks ago.. and it hasn’t gotten any better

  123. i was plating defense in soccer the other day (im 16 by the way) and i was going in for the ball when this girl ran into me and i fell to the side and felt my knee sort of crack. I couldnt get up right away and i was taken to the ER where they said it was really swollen but no signs of it being broken. I have to wear a knee immobilizer and i was just wondering what happened. i have to go see my ortho soon but i would like o know if it was a ligament tear… I cant really put any pressure on it because my knee feels weak and the back of my leg hurts really bad.

  124. When I sleep I sleep with my knees bent. And when I try to straighten them in the morning. It’s very painful and I feel a pop pop pop then I can slowly straighten it out. Any ideas?

    • Sometimes patellofemoral pain or early cartilage wear underneath the patella can cause a person to have crepitus or grinding sensation when flexing and extending the knee.

  125. I like to train in grappling and I seem to be icing every day 3 times a day now because I want to continue doing what I love. My knee gets better and then pops again and then gets better then pops again…. Its happen 4 times now and I’m just getting frustrated because it takes 3-4 weeks to get in to see my doc and every time I go see him I feel better and then I go train and pops again.

    I was diagnosised with a quad tear near the knee cap but no MRI has been done to confirm just X-ray. Is this normal for a quad tear?

  126. My knee for the past two months has been killing me, every step I take it feels as though my knee is try to buckle in. I ice it and put heating pads on it, but nothing is helping the pain, it’s slightly swollen but isnt bruised. I’ve also been wearing a compression sleeve on it. What can I do to help my knee? The pain is killing me.

  127. I’ve had two knee surgeries on the same knee for a toren lateral minicus and I think I tore it again. How can I tell?

    • Short of going to see an orthopaedic surgeon and having him or her examine you and order necessary studies, I don’t think there is an easy answer.

  128. Well I am 18 and since quite many times now my knee all of a sudden twists and goes back(original position) . It pains for a few seconds and then everything goes back to normal. But it has happened quite many times but with gaps (even months). Is there something that I should be worried about?

  129. This year early/mid January I was playing outside with friends. It was hilly out there so people would trip but it would just be funny because nobody got hurt in the process. (Hence the snow). We were playing zombie tag and I was it. Now, at one point I was running down a hill really fast, and one of my friends literally jumped in front of me, so I stopped abruptly and my knee gave out. It hurt so bad that I went inside. However, on the way inside I slipped on some tile and banged the hurt knee. It hurt for a week and a half and I had to sit down a lot.
    Now it’s April. I’m not saying that its continuous knee pain, but it pops a lot. Whenever it pops, it hurts for a split three seconds and I often find myself kneeling down on the floor. If I’m bending me knee and I feel it with my hand, it feels like a bunch of bumps and it sounds like the muscle is pulling – which I can feel too. It also pops if I’m squating or stretching (I take breakdance) or if I’m just bending it.
    Is it serious enough for the orthopedist? I’m twelve and my Mom says it ‘s growing pain and not to worry about it. I kind of have to disagree.

  130. So 6 days ago, I did the whole “plant and pivot” I had pain when it happened but then the pain just went away. But my knee/quad area is very very tight. It only gave away twice while walking but that’s it. I went to my trainer and he said possible tear or partial tear of my acl, I had little laxity in my knee but not too much. I then went to the doctor and all he said was a quad strain. Then I had relief. Then I started feeling better, I can now walk but I have swelling ( not very bad) in the top left corner of my knee cap. Then I went to my trainer again and he had me stand on one leg as a test. And that caused pain, that made me knee give out. But that’s the only pain I’ve felt since this happened. Is there a possibility that I tore my ACL?

    • I can’t say without examining you. That mechanism and a sensation of the knee giving way can be consistent with an ACL injury.

  131. i am a 15 year old boy who plays 3 sports. i tore my ACL and meniscus a little over year ago and had surgery exactly a year from last friday. I had a lacrosse game last friday and as i went to cut right my left knee (the surgical one) i felt really big pops on the right side of my knee and i fell down, i couldnt walk for a little but i played again later that game after swiftly faking to my coaches i was fine, it happened again and he took me out. then i could barley walk after, they next day i was having a lot of pain. my parents wont take me to the hospital or the docs they just want me to ice and take pain killers (like ive been doing). long story short im scared something bad happened and i could really use your advice, thank you for your time

  132. If I had knee surgery 2 years ago for ACL and meniscus repair and I had physical therapy and after six months I was doing a whole lot better the doctor cleared me to begin light workout. I ran a little and I played a little bit of vball and also a lot of other workouts at the gym. I then was able to run two half marathons, play more vball and actually be in the game. but then a month or so ago, I finally got to be a part of a futsal(indoor soccer in a basketball court) team and last night at my game, my knee gave out. it’s swollen and I am icing it and elevating it. Could I possibly have torn it again? Can I just keep resting it?
    I know this past few weeks because it’s been raining a lot my knee has been a little irritated when I’ve run. and I didn’t think about putting my brace on for yesterdays game but it gave out. Any feedback or comments?

    • Certainly it is possible for an athletic person for retear the ACL graft. If he or she is concerned about an episode where the knee gives way, it is worth having the orthopaedic surgeon examine the knee.

  133. My knee has been locking randomly for about 2 years and I have been in cross country (Running) should I go to the ER or urgent care since the Urgent care is not open can I go to the ER?

  134. im 14 i dont play sports.so i dont understand how i could of hurt myself. when i go to straighten my knee as i get up it hurts extremly. so i keep it straight most of the time when i sit i hope you can help me im concerened?

    • Could be where you are sitting for a long time and then getting up and the movement in your leg is having a quick reaction. Best to get it checked id say.

  135. I have no idea what happened to my knee. I’ve had pain for about 5 months now, it’s just increasingly getting worse. All I know is that it hurts to run and sometimes walk. I also play soccer,miso I don’t know if that has something to do with it. The thing is my knee isn’t swollen at all. Do you know what’s wrong.

  136. this site is amazing,,,,,,,, sir I am 16 yes girl and while playing with my friends I feel down at that time I heard some sound from my leg , now after10 days of injury I am not able to bend my knee and straight ,its painful and also I cannot walk much , doctor has given me a knee cap with support to walk with ..pls guide me what type of injury it might me and also about diet and also my knee is swollen since 10 days

    • I don’t think I can rally tell you based on just that description since I haven;t seen you or examined you. Generally the inability to bend or straighten the knee is concerning.

  137. Hello doctor.
    9 days ago I was running down a hill and landed very funny on my knee.. There was a popping feeling and I instantly could not bend it and walking caused sharp pains. I went to emergency and had an x-ray done and nothing was out of the ordinary but they did say there was a lot of fluid in the knee and prescribed me medication for it as well as gave me a shot to help reduce the inflammation. They also gave me crutches and a wrap to help secure my knee. 9 days later and no improvement. If anything, the swelling has worsened.. I am able to walk a small amount but it causes the swelling to increase. I can’t straighten my knee all the way and when I do, the kneecap moves upward with a pop and I need to bend it for it to be normal again.. I can also move the kneecap very easily by moving it with my hands. I saw my doctor and he referred me to a specialist and I know I’ll need an mri but I I don’t see the specialist until 5 days and I really have not been giving any thoughts of what this could be… Do you have any ideas? I don’t enjoy this waiting game..

    • Also, I’m a healthy and active 20 year old female and I’ve dislocated my knee before (I was 13 at the time) and the bone chipped and required surgery. This new problem involved the same knee if that information is helpful.. But It never caused me any problems before this injury.

    • Those symptoms could exist after several injuries. The orthopaedic surgeon, with or without an MRI, could likely give you a specific answer.

  138. Hello, I injured my knee at work exactly 8 days ago.

    What happened was I slammed it on a roofing tile and it hurt for a little while. I didn’t think too much and kept working another 6 hours or so. The next day I woke up, it felt fine and I worked for 4 hours or so, but then went home because the pain eventually got so intense. There was slight swelling but just a bit or miscoloration, NOT blueish “get to the ER now!” kinda swelling.

    Took the next week off and didn’t see the doctor, please don’t ask why…

    The first day it only hurt a small bit, while the next it did so much I could barely move my leg, although I was still walking around (with a limp.) I could, and can, still feel what appears to be a slight crack or something a little abnormal. Of course I RICE’d it for the next 3 days, took glucosamine/MSM and drank a lot of milk.

    I feel better now and am thinking of just resting it for 3 weeks or so and getting back to work. Of course I will see the doc if things get worse, but my question is, do I even need to see a doctor even if it feels fine or will just keeping it relatively immobile until it feels better be sufficient??

    • I can’t advise you on whether you should see a doctor. Generally I feel that if pain or other symptom after an injury is keeping an active person from doing what he or she wants to do, it can be a good idea to see an orthopaedic surgeon.

  139. Hi, I was on the Trampoline yesterday with my little nephews and I was bouncing when I heard a pop. I got off okay and pain shot through my leg to my knee.
    I had trouble driving home.
    I got home rested it and today I cannot straighten it nor walk on it without limping. Its not swollen just causes me pain. Its comfortable when at a bent angle but when it is straight it kills me?

  140. I’ve noticed the past 5 months pain in my knee if I bend it for a long period of time and then try to walk. I can’t straighten it or bear weight on it for a few seconds. I have not had anything happen. My guess is arthritis but it appears to be worse? It only happens when I bend it and then try to walk.

  141. I injured my knee, on the inner part of the right leg. It was hit hard and then I was unable to bend it or walk with out extreme pain. Unable to drive because of the pain,(took a week),said there was fluid and that was why I could not bend it. I still have a lot of pain when bending. I went to the ER, I was referred to a sports doctor, however they can not get me in until June (Obama care) anyway, I am still limping because it hurts and I can not sleep well due to pain. The pain has not gone away. In the past I had an open MRI, they said, I had Osteoarthritis. I am going on the 2nd week why is there so much pain?

  142. I’ve had some issues where it is very painful or impossible to jog or run for more than 5 or 10 seconds without my left knee hurting. It’s also very difficult to stand on my left leg and bend my knee and come back up again. I can do it, but it is uncomfortable.

    It seems to have been giving me issues for almost a year now since I started sprinting after a fair few months of inactivity. Seems to hurt just below my knee. I also have this in my right knee, but not to the same extent. It’s barely noticeable there.

  143. Last June I was playing football at school. I took a shot and my knee gave way. For about 8 months it was in pain and I couldn’t straighten my leg properly. The past 2 or 3 months my knee has been fine, but yesterday I played football and golf. I was getting pains during football and today I am in very bad pain if I put weight on it and I can’t straighten my leg again. Any suggestions on what could be wrong?

  144. When i bend my knee it hurts really bad like my right knee and when i sit for a long time it hurts, it has to be extended, I don’t know what is wrong. Also sometimes when i go to sleep my legs are bending and my right knee always hurt and i can’t like do squats or anything that involves it.. WHat is it?

    • I can’t really say without examining you. Pain with the knee bent often suggests patellofemoral pain syndrome.

  145. my knee has a sound and i cant bend it until the last it have pain inside and it twisted at first but now it changes to sound somties and really it is Uniqe and i belive you will answer me just i was playing football and when i was running i felt suddnely what shall i do???????

  146. i was training in the gym and suddenly i locked my knee, because i was not careful. i had a elastic rope around my knee, when i stood up. because of the presure of the rope pulling to the wall. i put my foot straight on the floor, while the elastic rope was pulling my leg to the wall. so my leg locked. i didnt paid much attention to it after wards.

    and still i keep doing sports without to much problem, when i actually doing bootcamp or any other sports i dont feel the acl at all, but after sports, sit on a chair and i put my finger on the middle point of the acl muscle it hurts like hell. also if i squad very deep, it hurts, not to much, but still it hurts.

    that said i still can do every sport. from running, to bootcamp, swimming, rowing. however i am little bit worried that overtime, the pain will increase and i cant walk anymore on the injured leg.

    i already have tinnitus which is already bad enough as it is, sports is the only thing that makes sure i dont hear any ringin in my ears because my brain focus on the muslce pains in my body when doing sports. so for me sport is actually the only thing that relaxes me, how crazy that may sound.

  147. I have this pain in my right knee that hurts when I straiten it or bend it sometimes. The pain is at the bottom of my knee and it hurts the top of my shin a little bit also the bottom of my right knee pops out a little bit more then the left one. Should I be worried about this or should I seek medical attention fast?

  148. Hi, in a cricket incident, I was hit by the ball inbetween the kneecap and the start of the shin. forcing a large crack/pop noise and knee cap to jerk up, but seam to be in place immediately, no pain the day after, although cannot fully lock knee or therefore fully tense quad, not because of pain but more of a restriction because of stiffness feeling with little pain. thanks

  149. I was doing heavy deadlifts a week ago and I got called back into work before I could complete my complete warm up and accessory work post lift. The following day about halfway through the day the front of my knee cap and behind the knee cap started hurting. I also had my knee cap on scaffold deck plate at work the night before. Not sure if I tore something of if I bruised it. It is painful to climb stairs, go down stairs and any type of squatting(no weighted). I know without a exam you can’t tell me much but I am wondering if I should be concerned? I am suppose to backpack 120 miles of the Appalachian Trail in September.

    • Pain under the patella (kneecap) typically isn’t worrisome, although you are correct that I can’t really give you advice. I think that if your symptoms aren’t getting better, it might be worthwhile to check it out and figure out a cause and treatment options before your trip. Have fun if you can go!

  150. when i was at boarding school we were playing kickball i ran to home base & this boy jammed the ball into my back my knee was the first part of me that hit the cement i had a bruise the size of a sausage patty. i had an ice pack on my knee but every time i run or sometimes when i play sports it hurts what is wrong with my knee

  151. Doctor I’m 11 and just recently I was playing football and I got tackled and the kid landed on my knee and from my knee down it all just bent upward… My dad said I hyper extended it but I really need to know please email me if u see this at Brady3250@gmail.com because after that it started to swell and I couldn’t walk now my kneecap can move side to side and my dad doesn’t want to take me to the doctor and says I’m fine I can walk on it now since its been two days but whenever I tried to walk I felt a pop on the side of my knee and it looks weird so plz email me at Brady3250@gmail.com

    • I really can’t give medical advice here or by email. Good luck Brady! If you see a doctor, please share what you find out!

  152. now when my knee hurts i limp and when i walk flat footed it tingles do you think it might dislocated because i can move my knee cap in circles so do you think it might be dislocated, torn ligament. do you think i might MRI or just go to my doctor’s office?

    • I think it’s best for patients to start by seeing their doctor or an orthopaedic surgeon before getting an MRI. A physical exam can often determine the need for these studies.

  153. at my boarding school i got this bruise on my knee from playing a sport & now every time i play a sport like basketball or running it starts to hurt but now i can roll my knee cap around i limp and when i walk flat footed my foot tingles is it dislocated or something? thanks

  154. I was coming down steps, got to the end and thought there was one step left, but there were really two. I tried to take the full distance in one step and my right knee buckled under the weight then banged into the brick wall in front of me.

    It’s six days later, there is still swelling on the inside part to the left of my kneecap and my knee can’t bend to 90 degrees yet. (More like 100-110. I am unable to sit on a table and extend my knee.

    X-ray said no broken bones. Does this sound like torn ligaments?

    • It’s hard to say without examining you. Those symptoms can certainly be consistent with structural damage like a meniscus tear, but an orthopaedic surgeon can give you more specific advice after examining you and ordering any necessary studies.

  155. I just got up from sitting down and I couldn’t put my leg straight, it only hurts if I try to extend it. it feels like two bones are going against each other. it’s not swollen or red or anything. it just locks right before its straightened out. I’m very worried and any kind of help would be so so appreciated!! I also got and X-ray today and they don’t understand why it hurts since it wasn’t from injuring doing anything physical.

    • I can’t really say what it is without examining you, but locking can be a sign of structural damage of some kind. You might consider seeing an orthopaedic surgeon and even possibly getting an MRI.

  156. I had PE and there i was running and somehow hurt my knee now i can’t bend or straighten it
    I went to the doctor but he said it was just a sprain or something like that but that was like 2 weeks ago and it still hurts

  157. Hi.

    I injured my knee in April, there was a pop and I suddenly felt a pain on the inside of my knee (collision on the outside of my knee). It slowly healed and in within a month i could run but I made sure that it was wrapped up with elastic knee brace just in case it gave in, it didn’t. This was about a month ago. After that I didn’t work it too hard. My knee bent and had full range of motion.

    This past week I started feeling some tightness in my knee, I felt a very dull pain in the back of my knee but then as the days went by I couldn’t straighten my knee. Then over the weekend I could but I could not bend it. You can understand how difficult it would be to even get into a car. Bending the knee even got harder as I couldn’t bend it past 45 degrees.

    Until today when I was getting into my car. As I was struggling to get in I accidentally bent it a little too far and I heard a ripping sound, it wasn’t painful but all of a sudden I felt relief, and I can bend it past 90 degrees. But I am really worried, what was that ripping sound? What should I do? My doctor still hasn’t told me what I injured the first time when I heard the pop.

    Please help me.
    If there is any more information that you require it is as below:
    Age: 27
    Gender: Male
    Country: Kenya
    Height: 6ft 1′
    Weight: 94kgs

    I have noted that my knee is started acting up while the cold weather has began to set in.

    Please help.

  158. Three years ago my right knee had total replacement. Had a great recovery/rehab, great range.
    Two hours ago, my Crocs slipped on wet concrete driveway and came down hard on same knee. I iced it immediately but it’s swelling like a goose egg on side of my patella. Very stiff, some painful.

    Earliest my Orthopaedic can see me is tomorrow morning.
    Is there anything I can do meanwhile except ice?
    Thank you for any advice.

  159. I had contusion on right knee while playing footbalI but no ACL. I can walk properly with mild pain sometimes. It’s been 4 weeks now, but today when I tried doing squats my right knee pained alot. It couldn’t bear any weight. Please help doctor.

  160. Just wonder if you know whats wrong with my knee, a little over 2 weeks I tripped and fell on my knee, it at first just seemed like a simple swelling and bruise but after the swelling went down there is a bump above my knee, not sure if its swelling or fluid but just to touch it is painful and hurts more then if I leave it alone, I dont have a doctor atm and to be honest I dont like going to the doctors because I was traumatized as a kid and avoid it at all cost. any advice will help, please

    • I can’t really say without seeing it and examining your knee. I do think seeing a doctor could be helpful. I hope it isn’t serious!

  161. I hit my knee very hard and I heard a crack but it wasn’t throughout the knee it was on the side of my knee it swelled up a little bit and today it is still swollen after more than 12 hours

  162. I have an accident couple of weeks ago… it got small swollen…. but after couple of week…. I don’t feel anything like scratching…. on that small swollen specific area.. can u tell me that is it a serious problem or just… not to worry

  163. Good morning, my daughter recently hurt her leg in practice. She was kicked by accident which caused her to fall on her leg in an awkward fashion. She did not hear a pop but was very painful to walk on immediately after. She did go to the emergency room and they did xrays which did not show anything. The emergency room doctor did advise that we see a sports clinic physician.

  164. What is it when you fall on your knee in basketball and it hurts for 6 months but I can walk on it but if I barely touch it. It starts hurting really bad and I have to sit and it almost puts me in tears. It hurts right below my knee on my right side

  165. I have a car accident almost four months ago (February 2015) and diagnosed with dislocated left knee. Early treatment, they just put back slab (POP) from my thighs to my ankle. My knee was then swelling so much I cannot even stand. After six weeks, they removed the back slab then I started to learn to walk again. First couple weeks I am still using stretchers to walk but after that I can walk normally without that. However, there are problems I noticed when I started to walk again. First, I cannot completely bend my left leg compared to my right leg. It is like there’s something holding my lower leg to bend and the pain seriously felt at the right side of my knee. But, after doing some exercises (which consult by physio doc), I can bend my knees more and more without pain but still not completely like my other normal knee. Second problem is, when I am sitting, my lower leg (tibia) seems to be flexible, meaning, can be moved front and back and doesn’t even pain, not like my normal right leg which doesn’t even move when I do the same test. Now, I can normally walk like I used to but still cannot completely bend my knee. Other than that, I feel pain in my knee when I am going down the staircase. Also, when I am standing a bit long, my knee seems to become weak or give away. Any comment doc..thank you.

  166. I played soccer 4 days back and on the field when I changed direction, I felt my right knee pop out to the outer side and came back into place but no popping sound. I felt pain at the outer side and back of the knee and could not bend my knees beyond 90 degrees or extend it completely. However I had little pain walking. The next day there was a swelling on the medial side and lesser swelling all around the knee. The doctor suspects it’s a meniscus tear or ACL. Throughout I’ve not had any issues with knee instability or knee giving away when I walk. My range of motion has improved over the last couple of days and the swelling too has gone down. I’m now able to bend by knee to about a 100 degrees and can extend completely with little pain still at the back of the knee. Moreover, I had an ACL surgery on the same knee 9 months back. I’m not sure what could be wrong and I dread an ACL retear. In the last visit to the OS, he checked my knee and confirmed I’m ready to return to sports.

  167. hi Im a young athlete a few months ago i done a competition in jumping and when i landed my knee moved out of place then back into place. for a couple of weeks it hurt but then was fine since then i have had a few occasions where i hurt it a small bit but today i was walking and the same thing happened it moved out of place but this time i couldn’t straighten it and its later on in the day and i still can’t straighten it! do you know whats happened? what can you suggest i do?

    • It could be several injuries, but it definitely seems worth getting it checked out. I’d try to see an orthopaedic surgeon to determine the extent of your injury.

  168. I’m having pain in knee in a specific spot. Pain started suddenly when I was playing football(I was not playing very aggressively. Also I didn’t got hit. There is no swelling at all. Also i can walk, ride cycle with a little pain. Is this serious?

  169. I hace a pain only when i fully go into a deep squat(butt past knees) and when i push up i de el a pain con the bottem left parte of my quad right above my knee but its not my muscle its on the inside.no pain when walking minimalista pain when doing a one legged jump. And idea what it is or how i can fix it?

    • I’m sorry, but I don’t really know without being able to examine you. You might see an orthopaedic surgeon who can examine you and order any necessary studies.

  170. I got a energy in soccer the other day and I can not pot a lot of pressure on it. I’ve tried to straighten my leg but when I do at a point I feel like something is in my way for moving it and it also really hearts.

    • Locking of the knee or inability to fully flex or extend it can be a sign of structural damage, so seeing an orthopaedic surgeon can be helpful for a patient with that symptom.

  171. When I run or hit a football very hard when my leg curls up to my quad it has a popping or clicking sound and it makes me immediately stop my workout and the same when I strike a ball it extends and makes a clicking or popping noise and I feel pain in my left side of knee on my right leg for 10-15 seconds and I don’t know why it reoccurs

  172. My daughter Haley her friend accidentally threw a rock at her and it hit her knee.she says that whenever she tries to bend it really hurts.

  173. I was doing a hand stand 5 months ago and I fell with my left knee bent (hitting the ground) and my right knee straight (supporting me). For the next couple weeks I couldn’t sit cress cross with out my left knee hearting very badly (my right knee felt fine). I finely went to my doctor 2 weeks ago and he told me it was runner’s knee and he gave me stretches to do(standing hamstring, quad, and standing calf). The stretches have been making it worse and now both knees heart because I walked/ran 10 miles in two days. I think I sprained or tore my ACL and I’m going back to my doctor tomorrow. Should I believe my doctor or what I think? and what should I do about it?

    • I can’t tell you if you should believe him or not. He does have the ability to examine your knee. An MRI can determine any soft tissue injury, like an ACL tear, that a patient might have.

  174. My daughter is 15. She plays select basketball year round as well as playing it for her school. Her right knee swells after playing every single time. She ices and elevates after each game. She was told she had jumpers knee. 2 months later, it is swelling in the back of the knee with limited mobility. It is very painful and when she bends her knee slightly, it is giving out with some popping. She said that down her back calf it feels like someone is “frogging” her. Upon her initial exam, the doctors said her knee caps are unusually loose but were not concerned as they both are. X-rays are negative. Any ideas?

    • I’m afraid I don’t have any, especially if her orthopaedic surgeon didn’t suspect any structural damage. I hope it turns out well!

  175. Hi, so about a few (2-3) weeks ago I was playing basketball and hurt my knee. There was no pop sound and there didn’t seem like any swelling but there was a dull pain that day. I’ve continued playing sports since then, I’m able to put my weight on my knee and all but for example today after playing basketball there was pain in my knee. Sometimes when I put pressure on my knee or a lot of weight it gives away but very slightly and regains right away. When I’m in a very specific position or move my knee very specifically then it pains. I’m able to perform everyday tasks it’s just once in a while each day it will pain and what I mentioned earlier. When I try to outstretch my knee after being seated for a while then it’ll hurt as well. Also you can note that I’ll be turning 17 very soon so I’m not really old at all. Now that I look at it carefully after a few weeks since it first started hurting the knee does look a bit more bigger than the left knee, maybe swollen a bit. I’m not sure what’s wrong and I’m confused because sometimes I feel like I need to get it checked and then other times it’ll be alright for quite some time. I need guidance please and thanks

  176. So I’m curious if you have to have all 7 of these symptoms. My legs won’t straighten all the way, and if they do it hurts. I also can’t crouch, and when I do it comes with immense pain. Getting back up from the crouch hurts as well plus the pain is mostly on the back of the knees. Not every symptom is relatable, but a few of them were. Do you need all 7 symptoms to be worried?

  177. I fell on my knee right into a steel step on the edge..Bang my knee good. My knee swelled up pretty big.. Went to the hospital but nothing broken.. But still after 3 days still feeling the extreme pain on my knee. Can I have turn something around my knee?

  178. I hurt my knee a couple weeks ago during ball hockey after it twisted when trying to quickly change directions. It buckled and started to swell soon after. I still do not have full range of motion in the knee and wear a brace for extra stability. I seen a doctor a week later when the swelling started to go down and he believes it is a meniscus tear however I cannot get an MRI for 5-6 weeks. If surgery is necessary can waiting this long cause further damage? It makes me nervous to just wait around while I wait for a correct diagnosis.

    Thanks

    • It is possible but hard to know without knowing the nature of an injury. In theory, a meniscus tear can be repairable initially but become damaged enough that it can no longer be repaired.

  179. Hi Dr.,

    I like to ride my road bike on the weekends in the mountains. I have never had any knee issues from cycling or any other activity. About 3-4 weeks ago, as I was opening a door at work, I smacked my left knee on the metal door frame pretty hard. I felt like I was almost going to puke there for a minute, the pain was so bad. For the rest of that day, it was difficult to walk because my knee hurt terribly. It was sore for the next few days and then the pain went away. In hindsight, I should have iced it and taken something for the inflammation, though I did not see any swelling. I did not ride for two weeks. When I did ride, it was a good long climb and I felt fine for the first 12 miles, then I began to fee pain in that knee around where the knee cap was smacked. feels like the pain is under the top portion of my knee cap (top being the edge closest to my hip). I was sore for a couple of days after that ride, but it went away. I went riding again, but this time I kept it to a flat ride and much shorter. The pain started up again about 10 miles into this ride. I am now taking Naproxen Sodioum, 440 mg in the am and 440 mg in the evening. I am thinking of seeing a doctor if this doesn’t clear up, and I will stay off of the bike for a couple of weeks. There is no popping, no problem or pain in bending my knee. It only hurts on a ride after about 40 minutes. If I were to see a doctor, what kind of doctor would you suggest that I see for this sort of thing? Thank you

  180. iwent to doctors and they told me i pulled ligaments and tendons in back of my knee but now its clicking but i can bend it and straighten it out and walk but a limp im wondering cud it be ACL able to bend and straighten

  181. I injured my knee from a fall almost two months ago. I had quite a bit of swelling and pain during the first 2 weeks following my injury.My doctor told me that he believed the injury to be a meniscus tear as I cannot straighten my leg, and feel pressure in the knee when I get to the end of my range of motion. The MRI showed that I have a bone bruise however. My doctor told me that with time the swelling inside of the joint will go down, and my full range of motion will return. Does this sound right to you? Everything I can find regarding locked knees is related to meniscus tears and I am unsure why a bone bruise would cause my leg to be unable to straighten without showing any signs of improvement in two months ( I have been going to physio every week). Thank you for your help!

    • Typically a bone bruise could cause pain and swelling, which can make getting full knee motion but not block motion itself. I hope it turns out well!
