Osteochondral defect is a broad term that describes the morphological change of a localized gap in the articular cartilage and subchondral bone 5. The talus is the bottom bone of the ankle joint. An osteochondral injury is an injury to the smooth surface on the end of bones, called articular cartilage (chondro), and the bone (osteo) underneath it.

Isolated lesions of cartilage or subchondral bone are not considered an OCD 6. OCD usually causes pain during and after sports. Dans la littérature, on trouve peu de cas de ce type de lésion et peu de renseignements sur le mécanisme de la blessure, les antécédents, les observations physiques et les recommandations thérapeutiques. Lesions affecting the cartilage of the tibial plafond are uncommon because of the biomechanical characteristics of the tibia. Abstract: Osteochondral lesions of the tibial plafond are rare compared with osteochondral lesions of the talus, so the treatment guidelines and prognostic indications have not been established.
