OCLs (osteochondral lesions of the talus) consist of damage or minor fractures to cartilage’s surface on the lower bone of the talus (ankle joint).
This cartilage covers most of the talus, with the tibia (shin) and fibula (calf) bones above and to the sides of the talus making up the ankle joint. The joint enables the ankle to move in a vertical plane. Injuries don’t always heal as effectively here, because of the below-average blood supply to this area of the body.
Injuries include:
- Cartilage damage
- Cysts in the bone under the cartilage
- Cartilage and bone fracture
