Osteochondritis dissecans (os-tee-o-kohn-DRY-tis DIS-uh-kanz) is a joint condition in which a piece of cartilage, along with a thin layer of the bone beneath it, comes loose from the end of a bone. Caused by reduced blood flow to the end of a bone, osteochondritis dissecans occurs most often in young men, particularly after an injury to a joint. The knee is most commonly affected, although osteochondritis dissecans can occur in other joints, including your elbow, shoulder, hip and ankle.
