Abstract
Osteochondral lesions at the talar dome are common causes of ankle pain and disability, however bilateral osteochondral lesions of the talus are relatively rare. The authors report a case of bilateral osteochondral lesion of the talus, and the arthroscopic treatment results.
A 12-year-old girl had complained of spontaneous bilateral ankle pain during athletic activity for 2 years. In December of 1998, radiographs revealed bilateral osteochondral lesions of the medial talar dome, both ankles were Grade 1 according to Berndt & Harty’s classification, and both were Grade 2 according to Kumai’s MRI classification. Arthroscopic findings in both ankles were Grade 2 according to Pritsch’s classification, arthroscopic treatment was done to fix the large fragment (8 mm) in the right ankle with Poly L-lactic acid osteosynthetic implants, and to fix the smaller similar fragment in the left ankle, with Kirschner wires (1 mm in diameter). The preoperative JOA score improved from 85 points to 100 points at the 1 year, 6 months follow-up.
