In recent years, degenerative meniscal lesions have received increasing attention as an etiologic factor of knee osteoarthritis. Among various relevant factors, medial meniscal extrusion has been shown to be an independent predictor of the onset and progression of knee osteoarthritis. Therefore, surgical reduction of the extruded medial meniscus to restore meniscal function is key to preventing osteoarthritis of the knee. The arthroscopic centralization technique using knotless anchors has been developed and refined to reduce meniscal extrusion in the posteromedial region of the knee. Although a short-term study has reported favorable outcomes, the technique presents some pitfalls and can be technically challenging. This article describes the rationale and procedure for arthroscopic belt capsulodesis using 2 knotless anchors for reduction of medial meniscal extrusion. The reported procedure is technically simple and efficiently reduces meniscal extrusion by repairing the meniscotibial capsule, and it may be useful in the prevention of osteoarthritic progression.
近年来，作为膝关节骨关节炎的一个病因，半月板退变损伤受到了越来越多的关注。在各种相关因素中，内侧半月板挤压已被证明是膝关节骨关节炎发病和进展的独立预测因素。因此，通过手术复位挤压的内侧半月板以恢复半月板功能是预防膝关节骨关节炎的关键。使用无结锚钉的关节镜下半月板复位技术已经得到发展和完善，以减少膝关节后内侧区域的半月板挤压。尽管一项短期研究报告了良好的结果，但该技术存在一些缺陷，并且在技术上具有挑战性。本文描述了使用2个无结锚钉进行关节镜下带状关节囊固定术以减少内侧半月板挤压的原理和操作步骤。所报道的操作在技术上简单易行，通过修复半月板胫骨关节囊能有效减少半月板挤压，并且可能有助于预防骨关节炎的进展。
