Medial meniscal posterior root tears are a well-known risk factor for knee osteoarthritis. Transtibial pullout repair is mostly reported, and good results have been reported for pullout repair using the modified Mason-Allen technique; techniques using suture anchors have also been reported. Herein, we report a technique for suture anchor repair using the modified Mason-Allen technique. An anchor with 2 sutures is inserted at the attachment site of the medial meniscal root via the posteromedial portal using a curved guide. A vertical suture was made on the posterior portion of the meniscus with one suture, and another suture is then inserted just medial to the vertical suture and tied over the first vertical suture using a self-locking sliding knot through the anteromedial portal. This technique may potentially improve medial meniscal posterior root tears repair outcomes and provide some technical advantages, especially in combination with high tibial osteotomy.
内侧半月板后根撕裂是膝关节骨关节炎的一个众所周知的危险因素。大多数报道的是经胫骨拉出修复术，使用改良的梅森-艾伦技术进行拉出修复已取得良好效果；也有使用缝线锚钉的技术报道。在此，我们报告一种使用改良梅森-艾伦技术进行缝线锚钉修复的技术。通过后内侧入路，使用弯形导向器将带有2根缝线的锚钉插入内侧半月板根部的附着部位。用其中一根缝线在半月板后部制作一条垂直缝线，然后通过前内侧入路将另一根缝线插入垂直缝线内侧，并使用自锁滑动结在第一根垂直缝线上打结。该技术可能会改善内侧半月板后根撕裂的修复效果，并提供一些技术优势，特别是与高位胫骨截骨术联合使用时。
