A subset of patients have residual rotational laxity following anterior cruciate ligament reconstruction (ACLR) despite the evolution of ACLR techniques. In recent years, there has been increased interest in addressing residual laxity because it is associated with poor outcomes after ACLR. There is an expanding body of knowledge on the anatomy and biomechanics of the anterolateral soft tissue restraints in regard to their rotational control of the knee and this has reignited an interest in extra-articular reconstruction techniques for augmenting ACLR. Reconstruction techniques currently used can be broadly categorized as either lateral extra-articular tenodesis or anterolateral ligament reconstruction. In this review, we discuss the relevant anatomy, biomechanics, and rationale behind the indications and technique of our current extra-articular augmentation procedure.
尽管前交叉韧带重建（ACLR）技术不断发展，但仍有一部分患者在ACLR后存在残余旋转松弛。近年来，人们对解决残余松弛的关注度日益增加，因为它与ACLR后的不良预后相关。关于膝关节前外侧软组织约束在旋转控制方面的解剖学和生物力学知识不断扩充，这重新点燃了人们对用于增强ACLR的关节外重建技术的兴趣。目前使用的重建技术大致可分为外侧关节外腱固定术或前外侧韧带重建。在本综述中，我们讨论了当前关节外增强手术的适应症和技术背后的相关解剖学、生物力学及原理。
