Outcomes of Meniscus Root Repair Using a Transtibial Pullout Technique


About this study

The results of this study will optimize the care for patients with a meniscus root tear. Surgeons will be able to determine if MRR (meniscus root repair) with transtibial pullout technique is an effective treatment and will identify potential risk factors for poor clinical outcomes. In addition, investigators will determine if MRR is successful in delaying the radiographic progression of arthritis in the involved compartment.
