Control of anterolateral knee laxity has always been a major goal of anterior cruciate ligament (ACL) reconstruction. The recent focus on the anatomy of the anterolateral knee and new studies demonstrating decreased graft failure risk with the additional of lateral procedures to intra-articular ACL reconstruction have given these procedures new relevance. A key question that drives indications is which patients benefit the most from these procedures. Those patients with increased rotational knee laxity, particularly in the absence of a repairable meniscus injury, may be good candidates. ACL injury chronicity, bony anatomy, concomitant anterolateral injury, and other factors all contribute to increased anterolateral knee laxity. This high laxity population is ideal for evaluation of the effectiveness of new methods to control knee laxity and improve outcomes of isolated intra-articular ACL reconstruction.
控制前外侧膝关节松弛一直是前交叉韧带（ACL）重建的主要目标。最近对前外侧膝关节解剖结构的关注以及新的研究表明，通过在关节内 ACL 重建中增加外侧手术可以降低移植物失败的风险，这些手术因此具有了新的相关性。一个推动适应证的关键问题是哪些患者从这些手术中获益最大。那些膝关节旋转松弛度增加的患者，特别是在没有可修复的半月板损伤的情况下，可能是很好的候选者。ACL 损伤的慢性程度、骨骼解剖结构、伴随的前外侧损伤以及其他因素都会导致前外侧膝关节松弛度增加。这种高松弛度人群非常适合评估新方法控制膝关节松弛度和改善单纯关节内 ACL 重建的效果。
