Osteoarthritis (OA) progression, medial meniscus extrusion (ME), and clinical outcomes were assessed as secondary objectives.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A comprehensive literature search was conducted following the 2020 Preferred Reporting Items for Systematic Reviews and Meta\u2010Analyses guidelines.

SLA was performed in all included patients. The proportion of successfully healed root repairs ranged from 5.9% to 50.0% in the isolated HTO group and 12.5% to 64.9% in the combined HTO\u2009+\u2009MMPRR group. Partially healed repairs occurred in 25.0% to 40.9% of isolated cases and 0% to 75% of combined cases, whereas failure rates ranged from 20.0% to 59.4% and 0% to 45.5%, respectively.<\/jats:p>\n                    <jats:p>Postoperatively, ME remained largely unchanged, ranging from 4.2 to 4.5\u2009mm in the isolated HTO group and 3.1 to 5.5\u2009mm in the combined HTO\u2009+\u2009MMPRR group. Improvement in OA grade was observed in 15% to 20.6% of isolated HTO patients and 4% to 20% of combined group patients, whereas OA progression occurred in 4.5% to 10% and 3.7% to 40.9%, respectively. Arthroscopic evaluation showed cartilage improvement in 17.6% to 40.0% of the isolated group and 3.9% to 53.8% of the combined group, with cartilage deterioration reported in 0% to 9.1% and 0% to 12.0%, respectively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Healing outcomes following MMPRR varied widely across studies, with outcome ranges showing higher healing rates and lower failure rates in the combined HTO\u2009+\u2009MMPRR group compared with isolated HTO.
