Osteochondral allograft (OCA) transplantation has been used to treat a wide spectrum of cartilage deficiencies in the knee, including spontaneous necrosis of the knee. Studies reporting outcomes after OCA transplantation have shown reliable improvement in pain and return to activities of daily living. We describe a single-plug, press-fit technique for OCA transplantation with concomitant high tibial osteotomy to treat femoral condyle chondral defects in a varus knee. Pearls and pitfalls of this technique are presented; attention should be paid to correction of concomitant joint pathology and malalignment to facilitate osseointegration and survivorship of the allograft plug into host bone. Appropriate surgical timing and prompt allograft implantation help to maximize chondrocyte viability.
骨软骨异体移植(OCA)已被用于治疗膝关节广泛的软骨缺损,包括膝关节自发性坏死。报道OCA移植术后结果的研究表明,疼痛得到可靠改善,患者恢复了日常生活活动能力。我们描述了一种单栓、压配技术,用于OCA移植并同时进行高位胫骨截骨术,以治疗内翻膝关节的股骨髁软骨缺损。介绍了该技术的要点和陷阱;应注意纠正合并的关节病变和排列不齐,以促进骨整合以及异体移植栓在宿主骨中的存活。合适的手术时机和及时植入异体移植物有助于最大化软骨细胞的活力。
