Costal osteochondral graft for a postoperative cartilage defect in a patient with polydactyly

Abstract

We present a case of a postoperative cartilage defect in a patient with polydactyly who was treated with a costal osteochondral graft. Excision of the radial digit and ligamentous periosteal flap with longitudinal osteotomy were performed when the patient was 1 year old. The alignment of the interphalangeal joint was straight after surgery, but the deviation gradually developed. A revision surgery using a costal osteochondral graft was performed when the patient was 3 years old. A satisfactory outcome was obtained at the 3-year follow-up. The authors suggest that a costal osteochondral graft may be a reasonable option for revision surgery for a postoperative cartilage defect.
