Cartilage+Injuries

One type of cartilage injury is OCD of the knee (Osteochronditis Dissecans), which is when part of the cartilage breaks off of the rest. In severe cases, OCD of the knee can cause complete in ability to move the knee. Many times, though, it only causes stiffness or catching of the joint. (Also see Meniscal Tears)

There is also chondomalacia, which is when the carilage softens. The softened cartilage allows the bones to rub together causing permenant damage. There is no swelling. Pain is common when going up and down steps and inclines with chondomalacia. It is caused by weakness of the knee muscles and overuse.
