Medial meniscal posterior root repair techniques have shown positive yet varied results in the literature. The decision to perform repair has improved clinical outcomes in many situations, although the healing rate is approximately 64% and the repair strength is roughly one-third of the native root strength, with meniscal extrusion being common. We present a technique based on biomechanical evidence to obtain a strong anatomic posterior root repair to restore nearly normal knee mechanics, combining an increased size of footprint under the lateral aspect of the medial meniscal horn for healing and a luggage-tag suture with a posteriorly placed horizontal mattress suture. The horizontal mattress suture is passed to capture the circumferential fibers of the meniscus and the luggage-tag suture is passed to capture the radial fibers of the meniscal body, through a single transtibial tunnel. The aim of this repair is to restore the normal meniscal function.
内侧半月板后根部修复技术在文献中显示出积极但多样的结果。尽管愈合率约为64%，修复强度约为天然根部强度的三分之一，且半月板挤压很常见，但在许多情况下，决定进行修复已改善了临床结果。我们提出一种基于生物力学证据的技术，以实现强大的解剖学后根部修复，恢复近乎正常的膝关节力学，该技术结合了在内侧半月板角外侧增加愈合区域的大小以及采用行李标签缝线和后置水平褥式缝线。水平褥式缝线穿过以捕获半月板的圆周纤维，行李标签缝线穿过以捕获半月板体的径向纤维，通过单个经胫骨隧道。这种修复的目的是恢复正常的半月板功能。
