We present a case of a 13-year-old boy with osteochondritis dissecans of the talus, in whom favorable outcomes were obtained by osteochondral autograft transplantation. He underwent arthroscopic fixation of the osteochondral lesions of the talus using polydioxanone pins, but came our hospital due to nonunion. Since pain in the ankle persisted, plain radiography and magnetic resonance imaging were performed. The results suggested stage 3 osteochondritis dissecans of the talus, according to the four-stage classification of Berndt and Hatty. We performed osteochondral autograft transplantation. At the time of writing this report 12 months postoparatively), the patient had experienced no pain and range of motion was not limited. In addition, radiolucency of the talus was restored.
