Abstract:
Most studies evaluating medial opening wedge high tibial osteotomy (MOWHTO) and medial meniscal tears and extrusion focus on the benefit of MOWHTO on meniscal healing. However, correcting medial meniscal extrusion with centralization or other techniques to augment meniscal repair may be necessary to maintain correction of MOWHTO. MOWHTO patients without MME >3 mm have more than 3 times higher chance of medial compartment International Cartilage Regeneration Society score improvement. This supports the idea that preserved meniscal function, and not MOWHTO alone, promotes cartilage healing and contributes to the long-term maintenance of alignment correction.
