Radiographic

images of the ankle of a 42 year old soccer player with weight-bearing pain for 9 months, showing osteochondritis dissecans of parts of the superio-medial talus. There is necrosis of subchondral bone, formation of loose fragments, as well as gas formation in the joint space. The projections are: Transverse plane by CT scan Coronal plane CT Sagittal plane CT Anteroposterior Projectional radiography

Triplane

osteotomy combined with talar non-weight-bearing area autologous osteochondral transplantation for osteochondral lesions of the talus. Case1, female, 31y, osteochondral lesions of left talus. A-E: preoperative imaging (X - ray and CT) supported the diagnosis; F-G: the lesion was exposed through the medial malleolus triplane osteotomy and debrided; H-I: AOT for OLTs from a non-weight-bearing area, and the donor defect was filled with a bone graft with periosteum from the tibia; J-M: at 37-month follow-up, imaging showed that the grafts had fused with the original bone in the talus, and the medial malleolus had achieved anatomic union
