The load-distributing function is most critical in meniscal function, and meniscal extrusion suggests failure of this function, leading to the progression of osteoarthritis. The arthroscopic centralization technique has been developed to reduce meniscal extrusion; however, existing arthroscopic techniques sometimes fail to reduce the most extruded region, especially in cases with a medial meniscus (MM) posterior root tear, in which the most extruded region is on the posterior border of the medial collateral ligament, which is very difficult to approach. This Technical Note describes an arthroscopic technique for extrusion of the MM in which a centralization technique using knotless anchors efficiently reduces the MM extrusion at the posteromedial part and consequently restores the MM function. This technique efficiently reduces MM extrusion and restores its function, thus preventing the progression of osteoarthritis.
负荷分布功能在半月板功能中最为关键，半月板挤压表明该功能失效，会导致骨关节炎的进展。关节镜下复位技术已被开发用于减少半月板挤压；然而，现有的关节镜技术有时无法减少最挤压的区域，尤其是在内侧半月板（MM）后根撕裂的情况下，其中最挤压的区域位于内侧副韧带的后缘，很难触及。本技术说明描述了一种用于MM挤压的关节镜技术，其中使用无结锚钉的复位技术可有效减少MM在后内侧部分的挤压，从而恢复MM的功能。该技术可有效减少MM挤压并恢复其功能，从而防止骨关节炎的进展。
