If you suffer a torn ACL in one knee and have surgery, how likely are you to suffer a second ACL injury? In this Ask Dr. Geier video, I discuss the possibility that you tear the ACL in the other knee after ACL surgery.

Fatimah asks:
I’m 17 years old. I had ACL reconstruction over a year ago. Currently I’m walking, running etc. It still pops on and off and feels stiff when cold. My other leg popped the other day. Can my other leg suffer an ACL tear from having ACL surgery previously?

ACL reconstruction surgery is generally very successful to restore stability to your knee. It is possible, though, to suffer a second injury. This can be a tear of the ACL graft in the knee you initially injured. Or you can tear the ACL in the other knee – contralateral knee.

How likely is it to tear the ACL in the other knee after ACL surgery?

In this video, I discuss how likely a second injury is, whether reinjuring the surgically reconstructed knee or the other, healthy knee is more common, and how you can decrease your chances of a second injury.
