I have the same story, went in for partially torn lateral meniscus, came out with medial femur microfracture. I was no weight bearing for 4+ weeks, and stayed home from work, laid on couch most of the time, used CPM for 3 weeks, and do exercises on my own now, flexion and extention of knee, abduction and adduction of the leg, calf extensions. Went back to work, stayed mostly non-weight bearing, but am not progressing to very lite foot to ground while using crutches. I have a long distance from car to office so it makes that trip a little easier, but I dont take a step without my crutches. I have a small amount of swelling when the m-fx took place, but it goes down a bit each day. I have darn near full ROM(compared to good knee). I am going to start taking some glucosamine(a few people said that might help), cant hurt I guess. I see my doc every other week. See him again at 6 weeks recovery, said we could start PT if I can be somewhat weight bearing w/out pain. I think I am doing okay, little pain, its more of a mild discomfort at times. My shoulders, chest and triceps are huge now from crutching everywhere!!! I dont ice as much as I should, btu I try to keep it up. Doc said everything looked okay, but not much to tell from looking.
Good luck everyone. It sure sucked waking up to 6 weeks of crutches. But if 6-8 weeks of barely moving means 30-40 years without as much knee pain, I'll do it.
