Recurrent posterior instability, resulting in posterior glenoid bone loss, or significant posterior glenoid bone loss at the index procedure can be a cause of failure of arthroscopic posterior stabilization repair. There are several described autograft and allograft options to restore posterior glenoid bone stock if the posterior glenoid bone loss is significant, generally greater than 20% of the surface of the glenoid. Advantages of a fresh distal tibia allograft include a contour near anatomic to the native glenoid with an articular surface that matches the humeral head through arc of motion and no associated donor site morbidity. This technique article outlines an approach to a failed arthroscopic posterior capsulolabral repair with an arthroscopic fresh distal tibia osteochondral allograft for recurrent posterior shoulder instability in the setting of glenoid bone loss.
复发性后方不稳定导致关节盂后缘骨质丢失，或初次手术时关节盂后缘出现明显骨质丢失，可能是关节镜下后方稳定修复失败的原因。如果关节盂后缘骨质丢失明显，通常超过关节盂表面的20%，有几种自体移植和异体移植的方法可用于恢复关节盂后缘骨量。新鲜异体胫骨远端移植的优点包括其外形接近天然关节盂的解剖形态，其关节面在活动弧度上与肱骨头相匹配，且无相关供区并发症。本文技术文章概述了一种针对关节镜下后方关节囊盂唇修复失败的处理方法，即采用关节镜下新鲜异体胫骨远端骨软骨移植来治疗关节盂骨质丢失情况下的复发性肩关节后方不稳定。
