case_images: The additional computed tomography (CT) scan confirmed the OCD, measuring 15 x 15 x 13 mm (Figure 1). In addition, the CT scan showed the presence of a large OT of 15 x 12 x 20 mm (Figure 1).
case_images: (A) The os trigonum (OT) was removed, (B) the osteochondral defect of the talar dome became visible and the cystic lesion was debrided, and (C) the OT was press fitted into the defect.

case_images: All cystic and necrotic bone was removed with a curette and chisel (Figure 2B) and the autograft recipient was (micro)drilled for bone marrow stimulation using a 2.0-mm drill. The proximal cortical bone was removed of the OT and prepared for optimal fitting (Figure 2A). By means of an impactor, the inserted autograft was fitted approximately 1 to 2 mm underneath the level of the talar cartilage (Figure 2C).
