新鲜同种异体骨软骨移植是治疗膝关节症状性软骨缺损的一种成功的单期手术。虽然长期研究显示患者报告的预后评分和移植物存活率有可靠的改善，但该程序的局限性包括移植物的可用性和在到期前及时使用。为了避免延长的手术等待时间和病变大小的进展，一些外科医生已经使用了非原位移植物(例如，股骨内侧髁病变的股骨外侧髁移植物)。此外，新鲜的预先切割的OCA核心可用于较小的症状性病变，从而避免与供受者大小匹配相关的手术延迟。我们描述了我们的首选技术，使用新鲜的预切开的OCA芯来治疗膝关节的小骨软骨缺陷。这项技术的显著优点包括一期修复关节表面，而不会出现自体骨软骨移植时的供区并发症。
Fresh osteochondral allograft (OCA) transplantation is a successful single-stage procedure for the treatment of symptomatic cartilage defects of the knee. Although long-term studies reveal reliable improvements in patient-reported outcome scores and graft survival, the limitations of the procedure include graft availability and timely use prior to expiration. To avoid prolonged surgical wait times and progression of lesion size, some surgeons have employed the use of nonorthotopic grafts (e.g., lateral femoral condyle graft for a medial femoral condyle lesion). Additionally, fresh precut OCA cores can be used for smaller symptomatic lesions, thereby precluding surgical delays associated with donor-recipient size matching. We describe our preferred technique for the use of fresh precut OCA cores for the treatment of small osteochondral defects of the knee. The distinct advantages of this technique include single-stage restoration of the articular surface without the donor site morbidity observed with osteochondral autograft transplantation.
