Restoration by Autologous Osteochondral Transplantation

Autologous osteochondral transplantation (AOT) is an osteochondral replacement technique. This procedure is indicated for large (>100–150 mm2) or cystic lesions. The surgical approach is determined by the location of the lesions, and adequate exposure of the lesions is essential for optimal results. Both medial and lateral tibial osteotomies have been used to obtain best exposure. The graft is typically harvested from the ipsilateral femoral condyle. Graft implantation should be flush with adjacent native cartilage surface. The clinical outcomes are promising in the short to medium term. Donor site morbidity and postoperative cyst formation have been reported in several studies. However, donor site knee pain does not appear to be a significant issue, and most cysts are not symptomatic and resolve over time.
