Well I'm about 3.5 months post op for arthroscopic surgery w/ microfracture to my right knee for some torn cartilege, and all has gone well, but there is one slight problem that I've had. After I got off crutches and finished my rehab (about a month ago) I didn't really have any more pain in my knee and thought i was cured. However, since then I haven't done any of my leg exercises other than jogging 3 times a week, and now my knee is a little more painful, especially when going up and down stairs and jumping. Is this just a case of my strength going down because I wasn't doing my exercises or is it something else? What would you guys reccommend?
