Meniscus root tears, while less common than tears of the meniscal body, are considered among the most serious meniscal lesions because of their effect on knee kinematics. Posterior tears of the meniscal root attachments are the most prevalent root tear pattern. Anterior meniscal root tears are less common and present unique challenges with visualization and instrument navigation for viable cortical fixation. Treatment options for meniscal root tears include nonoperative treatment, partial meniscectomy, or meniscus root repair. Repair is becoming more popular over partial meniscectomy; however, root repair techniques have a failure rate of about 20%. This technique describes an arthroscopic-assisted revision anterior horn medial meniscus root repair for failure of a previous repair. This revision technique involves a mini-arthrotomy to improve visualization of the medial meniscus anterior root attachment and to allow for a more secure repair. Outcomes and failure rates of revision meniscus root repair are comparable to primary repair, and revision should be performed to restore function and prevent medial compartment osteochondral degeneration.
半月板根部撕裂虽然比半月板体部撕裂少见，但因其对膝关节运动学的影响，被认为是最严重的半月板损伤之一。半月板根部附着点的后角撕裂是最常见的根部撕裂类型。半月板前根部撕裂较少见，在可视化和器械导航以进行可行的皮质固定方面存在独特挑战。半月板根部撕裂的治疗选择包括非手术治疗、部分半月板切除术或半月板根部修复。与部分半月板切除术相比，修复越来越受欢迎；然而，根部修复技术的失败率约为20%。本技术描述了一种关节镜辅助下的前内侧半月板根部修复翻修术，用于修复先前修复失败的情况。这种翻修技术包括一个小切口关节切开术，以改善内侧半月板前根部附着点的可视化，并实现更可靠的修复。半月板根部修复翻修术的结果和失败率与初次修复相当，应进行翻修以恢复功能并防止内侧间室骨软骨退变。
