As an important structure for maintaining the hoop tension of the medial meniscus of the knee joint, the posterior root is receiving increasing attention. Medial meniscus posterior root tear is an important reason for the occurrence, development, and kinematics changes of knee osteoarthritis. It is necessary to repair the posterior root of meniscus for restoring joint kinematics and improving clinical efficacy. This Technical Note reports a medial meniscus posterior root tear repair technique using arthroscopic transtibial pullout repair (ATPR) combined with tibial condylar valgus osteotomy. The aim of this technique is to repair the posterior root of the medial meniscus while correcting the force line through osteotomy, opening the joint gap, improving the joint surface fit, providing a good mechanical environment for meniscus repair, thereby improving the healing rate of the posterior root of the meniscus and reducing the risk of retear. Although clinical evidence is currently limited, we believe that this technology may have more clinical advantages compared with ATPR alone or ATPR combined with high tibial osteotomy.
作为维持膝关节内侧半月板环向张力的重要结构，后根受到越来越多的关注。内侧半月板后根撕裂是膝关节骨关节炎发生、发展及运动学改变的重要原因。为恢复关节运动学并提高临床疗效，修复半月板后根很有必要。本技术说明报告了一种使用关节镜下经胫骨拉出修复术（ATPR）联合胫骨髁外翻截骨术的内侧半月板后根撕裂修复技术。该技术的目的是修复内侧半月板后根，同时通过截骨矫正力线，打开关节间隙，改善关节面贴合度，为半月板修复提供良好的力学环境，从而提高半月板后根的愈合率并降低再次撕裂的风险。尽管目前临床证据有限，但我们认为该技术与单纯ATPR或ATPR联合高位胫骨截骨术相比可能具有更多临床优势。
