Please read and accept the terms and conditions and check the box to generate a sharing link. The severity of the osteochondral lesions was assessed according to the Anderson classification. The blood supply to the talus is not as rich as many other bones in the body, and as a result injuries to the talus sometimes are more difficult to heal than similar injuries in other bones. Among them, 10 (76.9%) were advanced-stage lesions (stages III and IV according to the Anderson classification).
