The purpose of this research is to determine if meniscus root repair with or without centralization will have an impact on postoperative pain, function, activity levels, patient satisfaction, and incidence of revision meniscus surgery.
Inclusion Criteria: * Type 2 Medial Meniscus Posterior Root Tear demonstrated on MRI * Notable extrusion (\>3 mm) on preoperative MRI * Patient able to consent for themselves * Patient agrees to comply with trial schedules and plan Pre-operative Exclusion: * Concomitant ligamentous or meniscal procedures * Meniscal extrusion \> 6 mm on pre-operative MRI * Kellgren-Lawrence grade \> 2 * Varus malalignment \> 10 degrees * Asymmetric varus alignment \> 5 degrees * Varus thrust while weightbearing * Grade 3 bipolar medial compartment changes (isolated grade 3 changes on single articular surface…
The centralization technique involves placement of 1.8-mm Knotless FiberTak suture anchors along the periphery of the tibial plateau, starting from the posteromedial corner and progressing anteriorly. The anchors are deployed using a curved drill guide, and sutures are passed in a mattress configuration to re-tension the meniscotibial ligament to centralize the meniscus. Once centralization is complete, the posterior root tear is repaired using an anatomic suture anchor for aperture medial meniscus root fixation.
The posterior root tear is repaired using an anatomic suture anchor for aperture medial meniscus root fixation.
