Data analysis included management strategy, surgical technique, meniscal extrusion, medial joint space, PROs, and radiographic measurements. Failure was defined as conversion to arthroplasty, subsequent partial medial meniscectomy (PMM) and\/or proximal tibial osteotomy, or clinical failure on PROs. Continuous outcome variables were analyzed with a random effects meta-analysis of mean differences. Chi-square meta-analysis was also used to analyze categorical variables.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Twelve studies were identified with &gt;5-year follow-up after PMMRT (mean \u00b1 SD, 84.1 \u00b1 11.0 months). Five studies performed PMM, 6 performed medial meniscus root repair (MMR), and 1 utilized either meniscectomy or repair. There were 797 total patients (female, n = 667; 83.7%), with mean ages ranging from 47.2 to 65. Both interventions showed significant PRO improvements after surgery: PMM (pre- vs postoperative Lysholm, 56.1 vs 68.2;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .01) and MMR (Lysholm, 52.1 vs 83.1; International Knee Documentation Committee [IKDC], 40.0 vs 72.8;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .01).

Additionally, PMM had a significantly higher failure rate (23% vs 5.3%) and conversion to knee arthroplasty (20.5% vs 3.5%) as compared with MMR, with odds ratios of 9.8 and 10.2, respectively.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>This systematic review and meta-analysis of studies with &gt;5-year minimum follow-up found that PMM was associated with a 10-fold increase in clinical failure and conversion to knee arthroplasty relative to MMR in observational studies. In addition, MMR demonstrated superior Kellgren-Lawrence grades and IKDC scores as compared with PMM. The findings of the current analysis suggest that MMR is associated with superior outcomes as compared with PMM at mid- to long-term follow-up.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/23259671261453326","type":"journal-article","created":{"date-parts":[[2026,6,15]],"date-time":"2026-06-15T16:13:01Z","timestamp":1781539981000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Medial Meniscus Root Repair Is Associated With Superior Outcomes As Compared With Partial Medial Meniscectomy at Minimum 5 Years: A Systematic Review and Meta-analysis"],"prefix":"10.1177","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-9996-0839","authenticated-orcid":false,"given":"Robert S.","family":"Dean","sequence":"first","affiliation":[{"name":"Corewell Health-Beaumont University Hospital, Royal Oak, Michigan, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryan","family":"McNassor","sequence":"additional","affiliation":[{"name":"Corewell Health-Beaumont University Hospital, Royal Oak, Michigan, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3248-8007","authenticated-orcid":false,"given":"Aaron J.","family":"Krych","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Mayo Clinic, Rochester, Minnesota, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brian R.","family":"Waterman","sequence":"additional","affiliation":[{"name":"Wake Forest Baptist Health, Winston-Salem, North Carolina, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,6,15]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.G.00748"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1002\/jrsm.12"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-018-5024-1"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546516662445"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546520920561"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2015.03.035"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2017.08.266"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1177\/23259671211038289"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cct.2015.09.002"},{"key":"e_1_3_3_11_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546518755754"},{"key":"e_1_3_3_12_2","doi-asserted-by":"publisher","DOI":"10.1177\/23259671241283962"},{"key":"e_1_3_3_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2025.01.005"},{"key":"e_1_3_3_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2010.01.032"},{"key":"e_1_3_3_15_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546512457642"},{"key":"e_1_3_3_16_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.csm.2019.08.009"},{"key":"e_1_3_3_17_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-020-05905-w"},{"key":"e_1_3_3_18_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-020-06151-w"},{"issue":"4","key":"e_1_3_3_19_2","first-page":"1117","article-title":"Partial meniscectomy provides no benefit for symptomatic degenerative medial meniscus posterior root tears","volume":"26","author":"Krych AJ","year":"2018","unstructured":"Krych AJ, Johnson NR, Mohan R, et al.
