Large, symptomatic, focal chondral, and osteochondral lesions of the ankle are treated with osteochondral autograft/allograft transplantation (OAT) procedure, a reconstructive bone grafting technique that uses one or more cylindrical osteochondral grafts from an area of low impact or allograft source and transplants them into the prepared defect site on the talus. This technique allows defects to be filled with mature, hyaline articular cartilage. Acute or chronic chondral or osteochondral lesions can be debilitating; provided here is a review of osteochondral autograft or allograft transplantation. OAT shows a trend toward greater longevity and durability and improved outcomes in high-demand patients.
踝关节的大型、有症状的局灶性软骨及骨软骨损伤采用骨软骨自体/异体移植（OAT）手术进行治疗，这是一种重建性骨移植技术，该技术从低冲击区域或异体移植源获取一个或多个圆柱形骨软骨移植物，并将其移植到距骨上准备好的缺损部位。此技术可使缺损部位填充成熟的透明关节软骨。急性或慢性软骨或骨软骨损伤可能使人虚弱；本文对骨软骨自体移植或异体移植进行综述。在高需求患者中，OAT显示出具有更长使用寿命和更高耐久性以及更好治疗效果的趋势。
