Abstract

Background For many years, osteochondral defects of the talus has been known as a symptomatic lesion that causes pain, recurrent synovitis, altered joint mechanics, and obstruction from loose bodies. It is a probable precursor of ankle osteoarthritis. Arthroscopic procedures, such as debridement, retrograde drilling, and bone grafting have a great advantage in treating small defects. An open method can be considered for treatment of large osteochondral lesions and unstable osteochondral defect lesions. Objective To present the functional results after autologous osteochondral transplantation in 12 patients using open surgical technique by antromedial approach and antrolateral approach for the ankle according to the site of the lesions, all lesions more than or equal to 1.5 cm the mean age of patients at the time of surgery was 20.5 years (range, 18–23 years), the mean follow up time was 27 months (range, 12–42 months), patient reported outcome measures were taken preoperatively and at final follow up using foot and ankle outcome score. Result The mean foot and ankle outcome score improved from 52.2 points preoperatively to 86.2 points postoperatively (range, 71–100 points). Two patients reported donor site knee pain after surgery, and one patient had delayed healing at medial malleolar osteotomy site.
