Anterior cruciate ligament (ACL) reconstruction is commonly performed; however, re-injury and graft failure remain significant concerns, particularly in high-demand individuals. Lateral extra-articular tenodesis (LET) has recently attracted attention as an adjunct to ACL reconstruction to reduce rotational instability and improve surgical outcomes. In this report, we describe four patients who underwent primary ACL reconstruction with additional LET. Despite experiencing significant traumatic knee events postoperatively, all four patients avoided ACL graft re-rupture. These cases suggest LET has a robust protective effect against ACL graft rupture, especially in patients at high risk for postoperative injury.
前交叉韧带（ACL）重建术是常见的手术；然而，再次受伤和移植物失败仍然是重大问题，尤其是在高需求个体中。外侧关节外肌腱固定术（LET）作为ACL重建的辅助手段，最近已引起关注，以减少旋转不稳定并改善手术效果。在本报告中，我们描述了4例接受初次ACL重建并附加LET的患者。尽管术后经历了严重的膝关节创伤事件，但所有4例患者均避免了ACL移植物再次断裂。这些病例表明LET对ACL移植物断裂具有强大的保护作用，尤其是在术后受伤风险高的患者中。
