Meniscal root injuries frequently occur in the setting of multiligamentous knee injuries. These present a complicating factor for planned tunnels and fixation owing to their proximity to the posterior cruciate ligament (PCL) tibial tunnel. Techniques typically aim to avoid tunnel convergence to reduce the risk of damage to grafts and/or fixation devices and decrease the risk of osteolysis or loss of fixation. We describe a method for planned tunnel convergence for PCL reconstruction and meniscal root repair. The PCL tibial tunnel is first drilled in the typical trajectory. An anterior cruciate ligament drill guide is then placed at the appropriate footprint for the medial or lateral meniscal root, with the starting point at the proximal tibia sharing the same external tibial tunnel aperture as the PCL. Sutures capturing the meniscal root and the PCL graft can then both be passed and exit distally via the same converging tunnel and can be fixed to the proximal tibia using standard techniques. The described technique can be used for either the medial or lateral meniscal root with concomitant PCL reconstruction in a safe and controlled method to reconstruct the native anatomy and avoid tunnel collision with inadvertent injury to grafts or fixation.
半月板根部损伤常发生于膝关节多韧带损伤的情况下。由于其靠近后交叉韧带(PCL)胫骨隧道,这些损伤给计划中的隧道和固定带来了复杂因素。技术通常旨在避免隧道汇聚,以降低移植物和/或固定装置受损的风险,并降低骨溶解或固定失败的风险。我们描述了一种用于PCL重建和半月板根部修复的计划隧道汇聚方法。首先按典型轨迹钻PCL胫骨隧道。然后将前交叉韧带钻孔导向器放置在内侧或外侧半月板根部的适当足迹处,起始点位于近端胫骨,与PCL共用相同的胫骨外侧隧道开口。然后,捕获半月板根部和PCL移植物的缝线都可以通过同一汇聚隧道向远端穿出,并可使用标准技术固定于近端胫骨。所描述的技术可安全、可控地用于内侧或外侧半月板根部并同时进行PCL重建,以重建正常解剖结构,避免隧道碰撞及意外损伤移植物或固定装置。
