The posterolateral corner (PLC), composed of three static stabilizers including the fibular collateral ligament, popliteus tendon, and popliteofibular ligament, collectively provide posterolateral knee stability (varus and external rotation). Disruption of this complex typically occurs in the setting of concomitant multi-ligament knee injuries (MLKI), typically requiring surgical management for restoration of knee stability. Anatomic surgical reconstructions have been shown to outperform non-anatomic reconstructions or repairs, yet are technically challenging and are not exempt of complications. The present review will address the anatomy and biomechanics of the involved structures, detail the senior author's anatomic three ligament tibiofemoral based reconstruction technique, and provide tips and tricks for avoiding the most frequently associated intraoperative and postoperative complications.
后外侧角（PLC）由三条静态稳定结构组成，包括腓侧副韧带、腘肌腱和腘腓韧带，共同提供膝关节后外侧稳定性（内翻和外旋）。这种复合体的损伤通常发生在伴有多韧带膝关节损伤（MLKI）的情况下，通常需要手术治疗以恢复膝关节稳定性。解剖学手术重建已被证明优于非解剖学重建或修复，但技术上具有挑战性且并非没有并发症。本综述将阐述相关结构的解剖学和生物力学，详细介绍资深作者基于胫股关节的解剖学三韧带重建技术，并提供避免最常见的术中及术后并发症的技巧。
