Hi, Dr. Geier,

Sorry for the interruption but I just have a brief question. I am currently a Division 3 soccer player, and I have a recurring injury on my right knee – an MCL sprain. I am hoping you can suggest a knee brace for me. Thanks for your time.


I have written previously about the use of knee braces to prevent injuries in football. That post looked at using knee braces to prevent injuries in athletes with no prior injury to the knee. This question is slightly different in that the reader has a recurring injury, so there is a more defined role for a brace in this setting.

An injury to the medial collateral ligament, or MCL, is very common in contact and collision sports, such as soccer and football. The injury almost always heals on its own without surgery, assuming that it is an isolated injury without a coexisting injury to either the ACL or PCL or a meniscus. I will say that if this is a recurring problem, I think that it is important to ensure by evaluation with a sports medicine physician and possibly x-rays and an MRI that there isn’t more going on.

The treatment for an MCL sprain is typically a brace to prevent valgus stress on the knee. This is a stress that tends to open up the medial side (inside) of the knee. A hinged-knee brace that allows the knee to bend but prevents side-to-side motion can do that. Unfortunately those braces are not really designed to be worn for playing. There are off-the-shelf braces from several companies that protect the MCL against valgus stress while playing sports. For an injury that typically heals in 2-6 weeks, one of those braces is usually adequate.

Custom-made braces to protect healing ligament injuries can be an option for playing for some athletes.

For an injury that keeps happening (and does not need more aggressive treatments or even surgery), then I might suggest a custom brace. These custom braces can protect the MCL (and some help protect the ACL and PCL) while being fairly comfortable during sports. Usually measurements of the patient’s thigh and calf are taken, and then the brace is made and shipped to the athlete a few days later. Also, custom braces are often more expensive, so checking with the insurance company might be a good idea.

It is important to remember that no brace completely eliminates the risk of reinjury or even makes playing possible in all settings, so I always recommend discussing return to play and the use of knee braces with a physician.

    I have a strained mcl and I have a knee brace but but doesnt really help. Can you give me a suggestion on what knee brace I should wear?

  2. Victoria says:

    And it has to be functional. I’m a cheerleader.

      Custom knee braces, like those worn by NFL offensive lineman, can be helpful for MCL injuries. They fit much better and are usually low profile enough to be worn during sports. A doctor orders them, and then a representative for the brace company usually takes measurements to have the brace made to fit the athlete’s knee.

  3. Tre says:

    What are the percentages of players in a contact sport ,such as american football, have knee injuries and return to play?

    • drdavidgeier says:

      Return to play depends on so many variables, especially what structures are damaged and to what extent, that it is really impossible to determine a percentage for all knee injuries. Hope that helps!

    I hurt my knee and i was walk on ice and i lost my step then i land on my knee :/ and i have being warm my knee brace and i hurt my knee last Saturday !!! I think i need to get a new knee brace

  5. Shannon Woodley says:

    I am an ice hockey goalie. I tore my MCL on my right knee. I have gotten back into the sport with a brace while playing. I have having trouble with the metal of the brace digging into my knee pretty severly when I drop into the butterfly to make a save. I am finding bruises and other injuries from the brace, even though it is inside my goalie pad. Is there a brace I can wear that will not dig into my knee when dropping onto the inside of my knee (a necessity when playing goal)?

    • drdavidgeier says:

      I think you would have to try different braces and find one that works for you. There are custom braces that protect the ACL that are specifically designed for sports participation, but hockey and being a goalie could be a problem. Also if an athlete’s MCL has healed, he or she might not need to wear a brace at that point.

  6. mark says:

    I’ve torn my mcl 12 times since the age of fourteen, all grade one and two. In the last 6 months its happened twice, both with little contact. My physio tells me its healed and not to wear a brace or support. and yet this problem reoccurs. Can you please give me some information and advice on braces or alternative action.

    • drdavidgeier says:

      I can’t give any specific advice without being involved in your care. I do think that custom braces potentially can decrease the chance of an athlete suffering an MCL sprain, as has been shown in several studies. If an athlete has suffered a ligament injury, especially a recurrent one, seeing an orthopaedic surgeon to determine if there are surgical options as well.

  7. Lauren Mcilmurray says:

    I have a grade two tear of my mcl can you recommend a brace that I can use for basketball

    • drdavidgeier says:

      I can’t recommend specific brands or types on my blog, but there are off-the-shelf and custom braces designed for MCL injuries from the different brace companies. Your orthopaedic surgeon can recommend options for you.

  8. KP says:

    I had ACL reconstruction on my right knee and then had issues with scar tissue (arthrofibrosis). In the interim, I sprained my MCL and we decided to hold off on pursing any MRI or additional diagnostic until after the LOA on my right knee and my right knee became strong again. In total, the MCL sprain was 4 months ago and I’ve had instabilitities about 20-30% of the time. Well I had the LOA on my right knee about three weeks ago and have been pounding away at PT (gotta get that extension back!) and my MCL on my left is toast – my left knee keeps giving out, especially after long days and PT.

    Is a brace even advisable at this point for the MCL or just continue to try RICE? Would a functional brace even help? I plan to bring up the MCL issues again with my surgeon at my 6 week visit (in 4 weeks) but determined not to give up in the interim. It’s only been a year of surgeries and PT!!

    • drdavidgeier says:

      I can’t really say specifically, so I agree with you asking your orthopaedic surgeon. I don’t think there is much downside to a brace for an MCL injury, but I can’t say how helpful it would be for you.
