Hi all, I injured my right knee in June 7 2011. The injury involved a already previously partially torn ACL which was finished off, and a torn medial meniscus that caused a permanent lock of the knee at about 100 degrees. Had surgery June 15 2011, ACLr with patellar autograph and medial meniscus repair. I was NWB for 4 weeks post op, and worked up to walking with brace locked at 0 degrees by week 6. Early on in the recovery I had slight problems with extension, and i was comforted by both physio and surgeon that it was caused by muscle weakness and/because of the knee being locked for a week before surgery. I'm now 6 months out and while it has come really, really far since then, I still occasionally have lots of stiffness and troubles with extension after sitting for periods of time. My good knee hyperextends a few degrees, and while warmed up my OPknee reaches 0 extension but does not hyperextend like my good knee. Is this a normal occurence? Have any of you had this operation and faced similar troubles? Will it improve? Should I be worried?
