关节镜诊断与全内修复半月板腓骨韧带撕裂
简介
本文介绍一种关节镜下诊断并全内修复半月板腓骨韧带(MFL)撕裂的技术。MFL撕裂是外侧半月板不稳易被漏诊的原因之一,常合并前交叉韧带(ACL)损伤,未予处理可致后外侧持续疼痛和半月板过度活动。技术要点为系统探查腘肌腱裂孔与后外侧沟、以动态探针评估外侧半月板并识别MFL撕裂,经标准前入路用全内垂直缝合重建MFL残端、后外侧半月板下缘与后外侧关节囊之间的连续性,…
英文摘要
Meniscofibular ligament (MFL) tears are an under-recognized source of lateral meniscal instability, frequently encountered in association with anterior cruciate ligament injury. Failure to identify and address MFL insufficiency may result in persistent posterolateral pain and meniscal hypermobility despite successful anterior cruciate ligament reconstruction. This Technical Note describes a reproducible, all-inside arthroscopic technique for the diagnosis and repair of MFL tears. Diagnostic arthroscopy includes systematic evaluation of the popliteal hiatus and posterolateral gutter, with dynamic probing of the lateral meniscus and identification MFL tear. The repair is performed through standard anterior portals, using all-inside vertical sutures to re-establish continuity between the MFL stump, the inferior border of the posterolateral meniscus, and the posterolateral capsule. This technique allows an anatomic, meniscus-preserving repair without additional open dissection or hardware in the fibular head. It is reproducible with standard arthroscopic equipment and can be combined with concomitant anterior cruciate ligament reconstruction.
