Osteochondritis dissecans (OCD) is a condition where part of the joint cartilage surface dies due to lack of circulation. Necrosis of the subchondral bone forms. A necrotic bone fragment can break away from the joint surface and end up in the joint as a foreign body and damage the joint capsule. Such a fragment usually has a diameter of 1 to 2 cm.<\/p>\n\n

Synonym: Osteochondrosis<\/p>\n\n

Osteochondrosis can affect the knee, hip, elbow, foot and also the spine, but it most often affects the knee (85% are in the medial femoral condyle). When it affects the knee, it is called K\u00f6nig’s disease or epiphyseal osteochondritis of the lateral femoral condyle. It is an osteonecrosis mainly of the medial condyle of the knee. This lesion is usually located on the posterior lateral aspect of the medial femoral condyle (70% of them). \n<\/p>\n\n

This osteochondritis becomes dissecting, as a separation of a fragment of bone and cartilage from the rest of the articular surface, occurs in a progressive way, to end up detaching completely, walking freely in the joint. \n<\/p>\n\n
