Treatment of osteochondritis dissecans of the talus: use of the mosaicplasty technique--a preliminary report.

Abstract

A one-stage autogenous osteochondral grafting technique for the treatment of talar dome osteochondritis dissecans is described. Eleven patients with osteochondritis dissecans lesions, 10 mm or greater in diameter, were operated on using the mosaicplasty autogenous osteochondral transplantation technique. Osteochondral cylindrical grafts from the ipsilateral knee were delivered into the talar defect using specially designed tube chisels. These procedures were done by arthrotomy. With follow-up of 12 to 28 months (mean, 16 months), the patients returned to full activities and the results, using the Hannover scoring system, have been excellent.
