Joint surface injury Discussion

Joint surfaces are covered with cartilage, which is soft and easily injured. Injuries which involve the surface of a joint always result in some degree of cartilage damage. Cartilage does not regenerate or heal like other body tissues, and outcome is unpredictable. Ideally, the joint surfaces should be restored to their original position and held there strongly enough that movement may be started in the early postoperative period. This is not always technically possible, and some cases cannot be helped by the most skillful surgery. Some permanent loss of motion is to be expected and the joint may develop degenerative arthritis as a result of the injury.
