Osteochondritis Dissecans Osteochondritis dissecans (OCD), happens when a piece of tissue that covers a joint (articular cartilage) is separated from the bone. Articular cartilage protects the bones and allows joints to move smoothly, without pain. OCD most commonly affects the knee joint, but it can also occur at the ankle, elbow, or other joints throughout the body. OCD occurs mainly in children and adolescents. Mild cases of OCD tend to heal over time, especially if a child has this condition. However, severe cases may require surgery to reattach the articular cartilage to the surrounding bone. CAUSES The cause of this condition is not known. Possible causes include: • Injury from repetitive motion or repetitive stress on the joint. • Inadequate blood supply to the joint. • Having certain genes that make developing OCD more likely (genetic predisposition). RISK FACTORS The following factors may make you more likely to develop this condition: • Being a child or adolescent. Having bones that are still growing makes OCD more likely to occur. • Participating in sports that put repeated force on the joints, such as distance running. • Being obese. • Having a family history of OCD. • Having posture problems, such as bow legs or knock knees. SYMPTOMS In many cases, there are no symptoms of this condition. However, symptoms vary depending on the severity and location of the condition. Possible symptoms include: • Joint pain
