This systematic review evaluated healing rates in patients with medial meniscus posterior root tears treated with isolated high tibial osteotomy (HTO) versus HTO combined with medial meniscus posterior root repair (MMPRR). Among 459 patients, the combined approach showed higher healing rates (12.5% to 64.9%) compared to isolated HTO (5.9% to 50.0%).
Key findings
- Healing rates for root repairs ranged from 5.9% to 50.0% in isolated HTO and 12.5% to 64.9% in combined HTO + MMPRR.
- Failure rates were 20.0% to 59.4% for isolated HTO and 0% to 45.5% for combined HTO + MMPRR.
- Medial meniscus extrusion remained largely unchanged, with measurements of 4.2 to 4.5 mm in isolated HTO and 3.1 to 5.5 mm in combined cases.
- Degenerative changes in osteoarthritis progressed in both treatment groups despite modest improvements in OA grade.
Why it matters
Understanding the comparative effectiveness of combined HTO and MMPRR versus isolated HTO can guide treatment decisions for patients with medial meniscus posterior root tears, potentially improving healing outcomes.
