Data Sheet 1_Impact of lateral meniscus injury on the efficacy of medial unicompartmental knee arthroplasty in patients with anteromedial osteoarthritis: a systematic review and meta-analysis.zip Jie Zhou (28945) Hongmin Deng (25090720) Mingjie Fu (25090723) Jinhua Guo (4523251) Qihao Jiang (19414972) Changyu Huang (1489528) Zhibing Gong (25090726) Surgery lateral meniscus injury medial knee osteoarthritis meta-analysis systematic review unicompartmental knee arthroplasty (UKA) Objective<p>To evaluate the effect of lateral meniscus injury on the clinical outcome of medial unicompartmental knee arthroplasty (UKA) for anteromedial osteoarthritis (AMOA), and to provide evidence-based support for clinical decision-making.</p>Methods<p>A systematic literature search was conducted across PubMed, Embase, Cochrane Library, Web of Science, Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI), Wanfang, and VIP databases from inception to March 1, 2026. Data synthesis and meta-analysis were performed using RevMan 5.4 software. Sensitivity and subgroup analyses were conducted where appropriate, and the certainty of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.</p>Results<p>A total of 8 retrospective cohort studies comprising 1,709 patients were included. No significant differences were observed between patients with and without lateral meniscal abnormalities in postoperative knee function scores [standardized mean difference (SMD) = −0.06, 95% confidence interval (CI) (−0.26, 0.14), P = 0.56], postoperative knee range of motion [mean difference (MD) = 0.17°, 95% CI (−1.58°, 1.92°), P = 0.85], or postoperative lateral knee pain [risk ratio (RR) = 1.10, 95% CI (0.32, 3.81), P = 0.89]. Sensitivity analyses showed that the pooled results remained stable. No consistent increase in revision or implant failure or lateral-compartment osteoarthritis progression was identified, although evidence for these outcomes was limited by the small number of events.</p>Conclusion<p>Available evidence suggests that asymptomatic or mild degenerative lateral meniscal abnormalities may not significantly impair short- to mid-term clinical outcomes after medial UKA in appropriately selected patients with AMOA. Therefore, an asymptomatic lateral meniscal abnormality alone should not necessarily be considered an absolute contraindication to medial UKA. However, these findings should not be extrapolated to symptomatic, unstable, traumatic, or root tears or to patients with advanced lateral-compartment cartilage loss.</p> 2026-09-22T15:33:06Z Dataset Dataset 10.3389/fsurg.2026.1913901.s001 https://figshare.com/articles/dataset/Data_Sheet_1_Impact_of_lateral_meniscus_injury_on_the_efficacy_of_medial_unicompartmental_knee_arthroplasty_in_patients_with_anteromedial_osteoarthritis_a_systematic_review_and_meta-analysis_zip/33966007 CC BY 4.0
