Preoperative MRI and Radiographic Parameters in Medial Meniscus Root Tears and Repair Outcomes

Plain-language summary

This retrospective observational study aims to investigate whether specific preoperative magnetic resonance imaging (MRI) and radiographic parameters are associated with medial meniscus posterior root tears (MMPRT), and whether these parameters have predictive value for mid-term clinical and radiographic outcomes after arthroscopic repair. Patients with arthroscopically confirmed MMPRT treated between 2020 and 2024 are evaluated based on their preoperative MRI and standing knee radiographs. Imaging parameters of interest include medial tibial slope, meniscal extrusion, tibial plateau depth, posterior root angle, and intercondylar notch morphology. Clinical outcomes are assessed using standardized scoring systems. The study aims to identify imaging-based anatomical risk factors to improve diagnosis, patient selection, and prognosis following MMPRT repair.
