Abstract:
Objective To evaluate the clinical results from the treatment of local chondral or osteochondral lesions on the talus dome with autologous osteochondral transplantation or mosaicplasty harvested from the ipsilateral knee. Methods There were 23 patients with chondral defects of the talus dome including post-traumatic cartilage defects(n=11), osteochondritis dissecans(n=9), and local osteoarthritis(n=3). The position and size of the defect were defined under ankle arthroscopy. The procedures consisted of debriding its edges and base drilled under ankle arthroscopy or arthrotomy, then harvesting osteochondral cylinders from non-weight bearing surface of the ipsilateral knee under arthroscopy, and using the osteochondral autograft transfer system(OATS) to implant the donor graft into the recipient holes of talus cartilaginous defects with press-fit technique. A single donor transplantation or the mosaicplasty was used. Results All the patients were followed up for 15 to 30 months(mean, 22 months). The mean pain intensity measured by standard visual analogue scale(VAS) reduced from 4.9?1.2 to 0.8?0.1 at final follow-up(P
