Just about a year ago over spring break I woke up a day after playing basketball and my left knee was totally screwed up. I couldn't move it at all with out huge amounts of pain. Well all of the pain went away after a month or so, the orthopedic had me taking lots of Motrin. Even after the pain went away I still had a problem with it, and that is when I crouch down, like I would for squats or leg press, then I get this popping around the upper left part of my left knee cap. When I squat down, if i put my fingers over that part of the knee cap, I can feel something kind of slide across it to make the pop. It also looks as if my left knee (injured) is skinnier than the right one. The orthopedic was not the greatest, he could never really classify my injury and told me it could be tendonitis. I really want to bulk up on my lower body for jumping, but this knee problem still scares me. There is no pain, just lots of akwardness. Anyone had anything similiar to this or know anyways to help fix this? Thank you for any help!
