BACKGROUND Joint pain and swelling are typical symptoms in children with juvenile idiopathic arthritis (JIA) and these are often related to inflammation of the joint. Juvenile osteochondritis dissecans (JOCD), that is separation of a bone-cartilage segment from the articular surface, can manifest with similar symptoms. FINDINGS We studied thirteen cases of osteochondritis dissecans lesions (O...

Introduction. Osteochondritis dissecans (OCD) of the capitellum is a localized disorder of the subchondral bone, in a region with limited healing capacity. Although its aetiology is still unknown, it has been associated with repetitive microtrauma. The natural history of this disease involves the evolution for degenerative joint disease in approximately half of the patients, with early identifi...

We present a review of the literature on classification and treatment of osteochondral defects of the talus. We report the case of an isolated Berndt and Harty grade II lesion treated with a fresh osteochondral allograft. We believe that fresh allograft osteochondral grafting of the talus is an excellent technique for symptomatic Berndt and Harty grade II or higher lesion of the talus without s...

Osteochondritis of the femoral condyles can be defined as a localized alteration of the trophism of the epiphyseal bone and articular cartilage opposite which may, without scarring, and necrosis to the release of an osteochondral fragment. This lesion is relatively rare, with around 20 per 100,000 boys and girls, and occurs in 70% of cases between 10 and 20 years. The pathophysiology of this co...

OSTEOCHONDRITIS DISSECANS (which is not to be confused with osteochondritis juvenilis) is a common disease but it is also a somewhat mysterious one. Its essential pathology consists of an avascular necrosis occurring in the sub-chondral bone of a joint followed by degenerative changes in the overlying cartilage. As the disease progresses, a zone of demarcation forms around the avascular area an...
