采用无结锚钉固定的改良Ellison技术行膝关节外侧关节外肌腱固定术
简介
改良Ellison LET技术结合无结锚钉固定，作为ACL重建的加强术式，可显著降低移植物失败率。该远端固定构型提供动态旋转稳定性，减少外侧间室过载风险，并避免股骨隧道汇聚。采用全缝线或硬体无结锚钉实现可靠固定，无需改变术后康复方案。
英文摘要
Lateral extra-articular tenodesis (LET) to augment anterior cruciate ligament reconstruction significantly reduces graft failure rates. Although there are many techniques for lateral extra-articular tenodesis, the modified Ellison technique provides numerous advantages as a distally fixed construct, including dynamic rotational stability, reducing the risk of lateral compartment overload, and eliminating femoral tunnel convergence. The addition of knotless anchor fixation provides a reproducible and efficient method for providing extra-articular stability to anterior cruciate ligament reconstruction without the need to alter postoperative rehabilitation protocols. We describe our preferred lateral extra-articular tenodesis technique utilizing the modified Ellison approach with both an all-suture knotless anchor and a hardbody knotless anchor to provide stable fixation while minimizing additional operative time during anterior cruciate ligament reconstruction.
