Greetings,

I ruptured my ACL, LCL, and Wikipedia reference-linkMeniscus playing soccer. I had surgery 3.5 months ago. The doctor used graft from my Hamstring to replace the CL's and trimmed the Meniscus tear. I exercise in the gym about 4x's wk - running on the treadmill and eliptical machines. Prior to surgery I couldn't run without my knee collapsing so that is an improvement. However, now my knee locks and (loudly) pops quite frequently. Prior to surgery it would do this some but not nearly as severely - it was not as firmly locked and the pop wasn't audible to others. I'm curious if others have had this trouble? If so, does anyone know what causes it and how to treat the problem? Many Thanks!
