A disorder of the joints in which cracks form in the articular cartilage and the underlying subchondral bone
Osteochondritis dissecans, often abbreviated to OCD or OD, is a joint disorder in which cracks form in the articular cartilage and the underlying subchondral bone. OCD is caused by blood deprivation in the subchondral bone. This loss of blood flow causes the subchondral bone to die in a process called avascular necrosis. The bone is then reabsorbed by the body, leaving the articular cartilage it supported prone to damage. The result is fragmentation of both cartilage and bone, and the free movement of these osteochondral fragments within the joint space, causing pain and further damage. In humans OCD is a rare disease, occurring in only 15 to 30 people per 100,000 in the general population each year. Although rare, it is an important cause of joint pain in physically active adolescents. Because their bones are still growing, adolescents are more likely than adults to recover from OCD; recovery in adolescents can be attributed to the bone's ability to repair damaged or dead bone tissue and cartilage in a process called bone remodeling. While OCD may affect any joint, the knee tends to be the most commonly affected, and constitutes 75% of all cases. OCD is also a growing concern, especially amongst women, in rural areas of Nigeria, according to research done by the University of Port Harcourt. This is due to the chemical pollution of primary sources of water used for drinking and irrigation in the area.
U.S. National Library of Medicine
