Persistent ankle pain could be due to a talar dome injury. The top of the talus bone, which forms part of the ankle joint, is dome-shaped and covered in a layer of cartilage. With an injury to this area, cartilage damage in the ankle and or damage to the underlying bone can occur. This is typically referred to as an osteochondral lesion or defect. It more commonly presents on the inside or medial aspect of the ankle but can affect the outer ankle too.
