Editorial Commentary: Medial Meniscal Root Repair Should Be Combined With High Tibial Osteotomy in Cases of Meniscal Extrusion.

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.
