Arthroscopic Medial Meniscus Posterior Root Reconstruction Using Auto-Gracilis Tendon.

ABSTRACT: There have been several techniques to repair the medial meniscus posterior root tears (MMPRTs) with the goal of restoring the anatomic and firm fixation of the meniscal root to bone. Many anatomic studies about the menisci also have been developed, so a better understanding of the anatomy could help surgeons perform correct fixation of the MMPRTs. The meniscal roots have ligament-like structures that firmly attach the menisci to the tibial plateau, and this structural concept is important to restore normal biomechanics after anatomic root repair. We present arthroscopic transtibial medial meniscus posterior root reconstruction using auto-gracilis tendon.

Project description:Concomitant medial meniscus posterior horn root tears and lateral meniscus posterior horn root tears are rare in occurrence. There is limited literature on the simultaneous repair of medial and lateral meniscus root tears, with ACL reconstruction. We discuss management of concomitant medial meniscus posterior horn root tear (MMPHRT), lateral meniscus posterior horn root tear (LMPHRT), and anterior cruciate ligament (ACL) tear. We highlight the surgical technique in which we perform a repair of both medial and lateral meniscus posterior horn root repairs with ACL reconstruction. We explain the sequence of such a repair to avoid tunnel coalescence. Technique Video Video 1 The patient is in the supine position with the knee in near extension with valgus stress applied. Pie crusting of the medial collateral ligament is performed to improve the visualization of the medial meniscus posterior horn root (MMPHR) tear. FiberTape (Arthrex, Naples, FL) and FiberWire 2-0 (Arthrex) are passed through the remnant of the medial meniscus root using an antegrade suture passing device; Firstpass Mini (Smith & Nephew, London UK). The tape and sutures are passed with an antegrade suture passer, working from the anteromedial portal and visualizing from the anterolateral portal. The footprint for the MMPHR is prepared, and a guide wire is passed using a low-profile jig set at 50°. The MMPHR tunnel is reamed with a 4.5-mm reamer. The suture and tape passed through the MMPHR are shuttled out and pulled out through the tibia tunnel. With the MMPHR reduced, three all-inside devices; Fastfix 360 (Smith & Nephew) are used to repair the complex horizontal meniscus tear and the posteromedial junction radial tear. These stitches—two to the posterior capsule and the third to the posteromedial capsule—helps to reinforce the medial meniscus to the posterior capsule. We then proceed to do the LMPHRT repair. In a figure-of-four positions, lateral meniscus posterior root tear is visualized. The footprint of the lateral meniscus root is prepared. FiberTape (Arthrex) and FibreWire 2-0 (Arthrex) are passed through the remnant of the lateral meniscus root using an antegrade suture passing device; Firstpass Mini (Smith & Nephew). The FiberTape is introduced through the anteromedial portal and the FiberWire is also introduced through the anteromedial portal (Fig 3C). This is to obtain the best trajectory to pass the suture through good meniscus tissue. A guide wire is inserted at the footprint of the LMPHR using a low-profile jig set at 50°. The LMPHR tunnel is reamed using a 4.5-mm reamer. The FiberTape and the FiberWire pulled out through the LMPHR tunnel. This is followed by ACL reconstruction and passage of ACL graft. The orientation of the tunnel in the proximal tibia from medial to lateral are the MMPHR tunnel, LMPHR tunnel, and ACL tunnel. The medial and lateral meniscus roots are tensioned individually and tied over the cortical button, following which, the ACL graft is fixed with a tibial interference screw.
