Introduction: Meniscus extrusion in medial meniscus posterior root tears (MMPRT) is a consistent MRI finding and correction of extrusion is a primary objective of the meniscal root repair. The purpose of the study is to evaluate feasibility of correction of extrusion and correlation of various factors affecting the postoperative extrusion correction and outcomes in all degenerative medial meniscus posterior roots (MMPRTs).
Methods: A retrospective study of patients who presented with degenerative MMPRTs following trivial incident (Jun 2014 and Aug 2018) and included isolated Laprade type 2 root tear with extrusion in MRI.
