Think I may have a knee injury...?

I was grappling w/ a friend of mine the other day and I went to push my foot off of his leg and as soon as my leg extended completely, I felt a pop in my knee. It's not unusual for my knees to pop, but this one was kinda painful. I haven't been able to fully extend it w/out it hurting since. It feels better on a daily basis, but the pain still persists when I stretch it completely out or in to sit on my foot. (can't sit on my foot at all right now) Any ideas on what this may be?? does it sound like just a sprain or something I should have an orthepedic doc check out??

Think I may have a knee injury...?
Yes, you should definitely get a referral to an orthopedic specialist.





There are several different types of knee injuries from cartilage (meniscus) tears to ligament tears. Popping sounds are very typical of ligament rupture. In your case, a hyperextension of the knee and symptoms you mention would likely indicate an injury to the anterior cruciate ligament. I ruptured mine as well and the popping sound was very evident. These ligaments do not heal and you will require corrective surgery and reconstruction. You are best to seek a professional opinion immediately as simple orthopedic tests can help diagnose the type of injury you may have.

Reply:It is potentially just a sprain but I would be worried about your meniscus (cartilage pad within the knee) or potentially the ACL (anterior cruciate ligament). Sometimes with full extension or flexion you can cause a tear in the meniscus. These sometimes can be taken care of with physical therapy but quite often they will require surgery (its through a scope and is outpatient). If it is the ACL, this usually requires reconstruction (also through a scope and outpatient). This is not an emergency so you don't need to rush to see a doctor but I would recommend seeing a sports medicine specialist (orthopedics or primary care sports).
