关节镜下全内修复腘肌腱裂孔前下束与后上束治疗外侧半月板过度活动症
简介
该文介绍了一种针对外侧半月板过度活动（由腘肌腱半月板束断裂或松弛引起）的解剖性全内修复技术，使用常规全内半月板固定装置分别修复前下和后上腘肌腱半月板束。该方法在恢复半月板稳定性的同时避免损伤腘肌腱，无需额外后方入路或移植物获取，易于推广。
英文摘要
Hypermobile lateral meniscus refers to abnormal mobility of an otherwise morphologically normal meniscus without obvious tears, causing lateral knee pain due to catching or locking of the lateral meniscus during flexion. The most common cause is rupture or elongation of the popliteomeniscal fascicles (PMFs), which connect the lateral meniscus to the joint capsule around the popliteus tendon. Hypermobile lateral meniscus is most commonly managed with simple, minimally invasive all-inside meniscal repair techniques or inside-out suture techniques. However, nonanatomic suturing not only results in unphysiologic repair but may also compromise popliteus tendon function. We describe a simple all-inside technique using a standard all-inside meniscal fixation device to anatomically repair the anteroinferior and posterosuperior PMFs. This approach reproduces the native fascicular anatomy while avoiding perforation of the popliteus tendon. The technique restores lateral meniscal stability, minimizes the risk of iatrogenic popliteus tendon injury, and does not require additional posterior portals or graft harvesting, allowing it to be performed with commonly available devices.
