The first revealed an OCD Lesion of the medial Talar dome, an injury that affected the cartilage between his Talus and Tibia and caused him pain and a ‘catching’ at the joint. MRI images show a stage IV medial talar dome osteochondral lesion with a minimally displaced osseous fragment corresponding to the plain films. Medial talar dome lesions are typically found in the central to posterior aspect of the talar dome and are therefore often inaccessible to arthroscopic procedures and techniques. Arthroscopy.
