改良经胫骨隧道拉出修复术联合倒刺缝线治疗内侧半月板后根部撕裂：一项技术要点
简介
本文介绍一种改良的经胫骨隧道拉出缝合技术治疗内侧半月板后根部撕裂，创新性地使用倒刺缝线以增强固定强度并均匀分布负荷。该技术通过倒刺缝线实现无结自锁固定，维持均匀张力，改善半月板中央化并减少外突，同时避免应力集中。该方法操作简便、可重复性强，兼容标准关节镜器械，并可联合中央化或其他辅助固定技术，适用于多种半月板根部撕裂类型。
英文摘要
This technical note describes a modified transtibial pullout repair for medial meniscus posterior root tear incorporating a barbed suture to improve fixation strength and load distribution. The technique combines 2 simple sutures placed near the torn root with a circumferential barbed suture passed through the posteromedial meniscocapsular tissue. The barbed suture provides knotless, self-locking fixation that maintains even tension across the construct, enhancing meniscal centralization and reducing extrusion. All sutures are retrieved through a single tibial tunnel and secured on the anterior tibial cortex with knotless anchors. This configuration restores proper tensioning and promotes physiologic hoop stress transmission while minimizing stress concentration and overconstraint. The method is simple, reproducible, and compatible with standard arthroscopic instruments. Moreover, it can be performed in conjunction with centralization or other adjunctive fixation techniques, offering versatility and adaptability for various meniscal root tear patterns.
