N2 - Background: The purpose of this study was to evaluate the clinical outcomes of mosaicplasty in the treatment of osteochondritis dissecans of the distal humeral capitellum. Materials and methods: Between 2003 and 2007, 10 patients (6 female and 4 male patients), with a mean age at surgery of 18 years (range, 13 to 27 years), with advanced lesions of capitellar osteochondritis dissecans underwent mosaicplasties. The surgical technique involves transplanting small-sized cylindrical osteochondral grafts from the lateral periphery of the femoral condyle at the level of the patellofemoral joint to the defect of the capitellum. At a mean follow-up of 30 months, all elbows were assessed with the Mayo Elbow Performance Score and a modified functional elbow score (Constant). Results: Postoperative radiographs and control magnetic resonance imaging/computed tomography images showed incorporation of the subchondral cortex in all patients. All but 2 patients were completely pain free after surgery. Of the patients, 8 (80%) had no reduction in range of motion. By use of the Mayo Elbow Performance Score, the injured elbow had a preoperative mean score of 71 points (range, 55 to 85 points) and increased significantly to a mean score of 93.5 points (range, 85 to 100 points) postoperatively (P = .0005, paired t test). The nonoperative elbows had a mean score of 100 points, whereas the operated elbows had a mean score of 93.5 points. The functional elbow score showed a mean difference of 7.5 points between the operated and nonoperative elbows. No infection or neurologic deficit developed after surgery in any case. Conclusions: Autologous osteochondral mosaicplasty for advanced lesions of capitellar osteochondritis dissecans can provide satisfactory clinical and radiographic results.
