Osteochondral allograft transplantation is a viable option for large chondral defects >2 cm squared, as well as in a revision setting after failure of a previous surface chondral restoration procedure. Osteochondral lesions involving the posterior aspect of the femoral condyle, however, are less common and easily underappreciated. Treatment of posterior osteochondral lesions is more technically demanding because they cannot be adequately addressed through standard arthroscopic approaches or an anterior arthrotomy. The challenges of the posterior approach include the relative unfamiliarity for many surgeons and the inherent risks due to the proximity of the neurovascular structures. The following technique reviews relevant anatomy and approach to osteochondral allograft transplant involving the posterior femoral condyles.
异体骨软骨移植是治疗面积大于2平方厘米的大面积软骨损伤以及既往表面软骨修复手术失败后翻修手术的一种可行选择。然而，累及股骨髁后方的骨软骨损伤较少见且易被忽视。由于无法通过标准关节镜入路或前方关节切开术充分处理，股骨髁后方骨软骨损伤的治疗在技术上要求更高。后方入路的挑战包括许多外科医生对此相对不熟悉，以及由于神经血管结构靠近所带来的固有风险。以下技术回顾了涉及股骨髁后方异体骨软骨移植的相关解剖结构和入路。
