What Causes Knee Pain Behind or Around the Kneecap (Chondromalacia)?
This type of knee pain and the softening of the kneecapās articular cartilage can be caused by: Trauma can cause knee pain. Overuse can add to your knee pain. Muscle weakness can contribute to knee pains. Mal-alignment can cause knee pain. Age is a factor to consider when evaluating what caused your knee pain. Over-pronation can lead to mal-alignment, which means the lower leg twists inward while the quadriceps tendon pulls the patella outward. A tight hamstring, tight heel cords and tight quadriceps also contribute to the problem. Young people who develop this kind of knee pain can usually blame trauma or overuse; if this type of knee pain appears in someone older, this person may also have osteoarthritis.
