I am facing this issue of pain on back of knee while bending the knee backwards.I have a history of tibial condyle fracture which happened in 2008 and hence have developed osteoarthritis because of it. I consulted a orthopedic doctor and he suggested to take glucoseamine and
calcium for it .I had consulted another doctor before him who claimed that the pain is due to strained muscle on back of knee. The pain is there only when i am bending the knee and not while walking.I am totally confused wether this is a arthritic pain or muscle pain.Kindly guide?
