Osteochondritis Dissecans of a Joint
Osteochondritis dissecans (OCD) is a condition in which a piece of bone or cartilage (or both) inside a joint loses blood supply and dies. OCD may be caused by injury or overuse from an activity that repeatedly jams one bone end against another.
OCD may not cause any symptoms, or symptoms may begin suddenly, develop gradually, or come and go. The condition may be discovered by accident if an X-ray is taken for another reason.
Symptoms of OCD may include:
Treatment focuses on resting the joint to allow the cartilage and bone to heal and the swelling to decrease. The bone may take a full year to heal. Surgery may be necessary to remove or repair loose pieces of bone.
