Autogenous osteochondral grafts have recently become popular for use in small, isolated, contained articular cartilage defects. We treated a 26-year-old man who had a cartilage defect measuring 10 x 20 mm in the anteromedial area of the right talus. We performed multiple osteochondral grafting of the lesion with medial malleolar osteotomy from a donor site in the ipsilateral knee joint. Two years after the operation, the patient's ankle pain recurred and the bony lesion in the talus also became osteolytic. Because we believed that only the cartilaginous portions of the osteochondral plugs grafted 2 years previously were fully fixed and viable, and that recurrence had occurred at the bony portions, at reoperation we performed curettage of the bony lesions and grafted iliac bone into the lesions with fenestration of the inferomedial ankle joint cartilage, not grafted plug cartilage. Therefore, probably because of overuse, the bony lesion in the talus had recurred 2 years after the first operation, but the grafted hyaline cartilage had survived. Autogenous osteochondral grafting into the talus, unlike the knee joint, should be done with care to ensure there is no sclerotic bone surrounding the lesion in patients with long-standing symptoms and recurrence of bony lesions.
