Medial meniscus extrusion (MME) is classically defined as radial displacement of ≥3 mm outside the tibial border. MME is usually seen in middle-aged patients, and it is strongly associated with medial meniscus root (MMR) pathology and medial femorotibial compartment degenerative change. MMR tears are associated with cartilage defects of the medial femoral condyle (89%) and MME ≥3 mm (67%). If MMR tears are associated with MME, high tibial osteotomy combined with MMR repair may reduce MME and protect the medial compartment. Recent research shows combined MMR repair and high tibial osteotomy yield improved radiographic and functional outcomes.
内侧半月板挤压（MME）传统上定义为在胫骨边缘外侧径向位移≥3毫米。MME通常见于中年患者，并且与内侧半月板根部（MMR）病变和内侧股胫关节间室退变密切相关。MMR撕裂与内侧股骨髁软骨缺损（89%）和MME≥3毫米（67%）相关。如果MMR撕裂与MME相关，高位胫骨截骨术联合MMR修复可能会减少MME并保护内侧间室。最近的研究表明，MMR修复与高位胫骨截骨术联合应用可改善影像学和功能结果。
