Arthroscopic posterior cruciate ligament (PCL) reconstruction is a technically demanding procedure, particularly with respect to tibial footprint debridement and tibial tunnel placement, where iatrogenic damage to anatomic structures is a well reported complication and incorrect tunnel placement can have functional implications. Preparation of the tibial component often involves switching between 30° and 70° arthroscopes and frequent portal swapping and reorientation, which can be inefficient and time-consuming. As the technology and picture resolution of needle arthroscopy has improved, its clinical application has widened. This manuscript describes the use of needle arthroscopy-assisted arthroscopic PCL reconstruction for optimal visualization of the PCL tibial footprint using an accessory posterolateral portal, while obviating the need of both 30° and 70° arthroscopes.
关节镜下后交叉韧带(PCL)重建是一项技术要求较高的手术,特别是在胫骨足印清创和胫骨隧道定位方面,医源性损伤解剖结构是一种常见的并发症,而不正确的隧道定位可能会影响功能。胫骨部件的准备通常需要在30°和70°关节镜之间切换,频繁更换和重新定位入路,这可能效率低下且耗时。随着针状关节镜技术和图像分辨率的提高,其临床应用范围也在扩大。本文描述了使用针状关节镜辅助关节镜下PCL重建,通过辅助后外侧入路实现对PCL胫骨足印的最佳可视化,同时无需使用30°和70°关节镜。
