关节镜下半月板后根部全缝线锚钉联合改良经胫骨隧道拉出修复术
简介
该文介绍了一种使用全缝线锚钉结合改良经胫骨隧道拉出技术修复外侧半月板后根部撕裂的方法。通过在半月板表面形成缝线球进行固定，并在解剖足印区建立2mm胫骨隧道完成再固定。该技术可实现稳定、微创的解剖修复，减少骨量丢失，避免与ACL移植物隧道干扰，并促进生物学愈合。
英文摘要
Lateral meniscus posterior root tears lead to disruption of hoop tension, elevation of contact pressure, increased knee instability, and accelerated cartilage degeneration of articular cartilage. Anatomical repair is required to re-establish normal knee biomechanics and to slow the progression of osteoarthritis. A modified transtibial pull-out technique using an all-suture anchor is described. The tail suture is applied for root fixation, creating a suture ball on the meniscal surface, while a 2 mm tibial tunnel is created at the anatomic footprint to achieve refixation. This technique provides stable, minimally invasive, and anatomical repair, minimizing bone loss, avoiding tunnel interference with anterior cruciate ligament grafts, and promoting biological healing.
