Hoping some of you guys can give some advise here. I got MRI results back today and was told that I have a bruised bone in my left knee and 2 "Partial" Tears in my right knee. Im not sure how this happened, all I know is it happened months back. My question is on training, doctor said he wants to hold off on surgery for now but doesnt want me to do any squats or bend the knee more than 30 degrees....So Im not sure what I can do that might help strengthen things up? Any advise would be helpful. Thanks!!
