Tears of the posterior medial meniscus root commonly result in extrusion of the meniscus and disruption of tibiofemoral contact mechanics. Transtibial pull-through repair of the root often results in healing of the tear, but postoperative extrusion may persist. In this scenario, the meniscus is unlikely to be chondroprotective. Therefore, an additional centralization procedure is necessary to improve the extrusion. Biomechanical studies have demonstrated that centralization can improve meniscus mechanics and potentially reduce the risk of osteoarthritis. This Technical Note describes an arthroscopic technique for medial meniscus posterior root repair that combines transtibial pullout and centralization sutures.
后内侧半月板根部撕裂通常会导致半月板挤出以及胫股关节接触力学的破坏。根部的经胫骨拉出式修复通常会使撕裂处愈合，但术后半月板挤出可能会持续存在。在这种情况下，半月板不太可能起到软骨保护作用。因此，需要额外的复位手术来改善半月板挤出情况。生物力学研究表明，复位可以改善半月板力学性能，并有可能降低骨关节炎的风险。本技术说明描述了一种关节镜下内侧半月板后根修复技术，该技术结合了经胫骨拉出缝线和复位缝线。
