Autologous mosaicplasty has been widely used for the treatment of focal, full-thickness, articular cartilage lesions of the knee and ankle joints. Commonly, the autografts are harvested from non-weight-bearing areas of the knee joint, leading to associated donor-site morbidity and representing a considerable disadvantage. This Technical Note presents a mosaicplasty procedure for harvesting autologous osteochondral plugs from the upper tibiofibular joint to repair articular cartilage defects. With this technique, it is possible to achieve low or no risk of donor-site morbidity, being therefore a safe and favorable option to treat large cartilage defects. Because of its minimal size-related restrictions, it enables harvesting larger plugs (filling an area up to 5 cm) without any additional iatrogenic complications. Hence, mosaicplasty using the upper tibiofibular joint autografts can overcome many of the reported complications associated with osteochondral autograft harvesting. Thus, the upper tibiofibular joint articular surface should be considered as a safe and reliable autograft source for harvesting osteochondral plugs.
自体镶嵌植骨术已广泛应用于膝关节和踝关节局灶性、全层关节软骨损伤的治疗。通常,自体移植物取自膝关节的非负重区域,这会导致相关供区并发症,是一个相当大的缺点。本技术说明介绍了一种从胫腓上关节获取自体骨软骨栓以修复关节软骨缺损的镶嵌植骨手术。采用这种技术,可以实现供区并发症风险低或无风险,因此是治疗大面积软骨缺损的安全且有利的选择。由于其与尺寸相关的限制最小,它能够获取更大的骨栓(填充面积可达5厘米)而不会产生任何额外的医源性并发症。因此,使用胫腓上关节自体移植物的镶嵌植骨术可以克服许多与自体骨软骨移植获取相关的报道并发症。因此,胫腓上关节关节面应被视为获取骨软骨栓的安全可靠的自体移植物来源。
