2 months sounds like a long time - but I'm not a doc! I would wait until it "feels" healed than do very a very light leg workout. I do know that your legs loose their mobility from non-use - so at least move them "all-around, full-range" with no weight and not in any position that bothers that knee.
You could work your "good leg" individualy on machines but don't put yourself in a position that compromises your recovering knee.
It doing better buy the day. no pain just some swelling so its pretty stiff. but this was a perfect time to have this done, i just finnished a 10 week cycle and next week i will be done with that dam clomid. so buy the time my knee is 100% it will be cycle time again.
