Abstract

The structures of the posterolateral corner (PLC) work together as a single unit to provide both static and dynamic functions to the knee. Multiple techniques have been described for PLC reconstruction, however most of these techniques re-establish the static function of the PLC without addressing dynamic components. The popliteus muscle serves an important role in providing dynamic stability to the PLC, but this function is often not restored in reconstruction techniques. We describe a novel technique for PLC reconstruction that includes popliteus repair, and review the functional anatomy and biomechanics of the PLC. We also confirm the dynamic stabilizing role of the popliteus muscle through a biomechanical analysis of four cadavers.

一种新型关节镜辅助下腓骨双重建腘肌修复技术治疗后外侧角损伤：尸体和功能解剖研究

后外侧角（PLC）的结构作为一个整体一起工作，为膝关节提供静态和动态功能。多种技术已经描述了PLC的重建，然而，大多数这些技术重建PLC的静态功能，没有解决动态组件。腘肌在为PLC提供动态稳定性方面起着重要作用，但这种功能在重建技术中往往无法恢复。我们描述了一种新的PLC重建技术，包括腘肌修复，并回顾了PLC的功能解剖和生物力学。我们还通过对四具尸体的生物力学分析证实了腘肌的动态稳定作用。
