Abstract:[Objective] To evaluate the clinical outcomes of meniscal allograft transplantation (MAT). [Methods] The literatures wereretrieved from CNKI, CBM, Wanfang, VIP, PubMed, Embase and Cochrane Collaborative Library databases up to October 1, 2023. Accord-ing to the inclusion criteria, literatures with an average follow-up time of 10 years or more after MAT were collected. After reading the full pa-per and extracting the data met the including criteria, a meta-analysis was conducted by using Revman 5.3 software. [Results] Ten papers,involving 382 patients, and 395 menisci, were included, with a mean follow-up of 13.4 years. As meta analysis results, there were no statisti-cally significant differences in terms of Tegner and VAS scores after MAT surgery compared with those before surgery (P>0.05). However, ,Lysholm score (MD=-18.29, 95%CI -26.33~-10.26, P<0.001); KOOS score [pain: (MD=-16.67, 95%CI -28.63~-4.71, P=0.006), symp-toms: (MD=-14.25, 95%CI -26.52~-1.97, P=0.02), activities of daily living: (MD=-14.34, 95%CI -21.33~-7.35, P<0.001), sports and rec-reation: (MD=-14.87, 95%CI -24.84~-4.91, P=0.003), quality of life: (MD=-14.69, 95%CI -26.48~-2.90, P=0.010)]; IKDC score (MD=-23.59, 95%CI -27.42~-19.75, P<0.001) and SF-36 [physical health (MD=-15.98, 95%CI -20.10~-11.87, P<0.001) and mental health(MD=-15.58, 95%CI -20.97~-10.19, P<0.001)] increased significantly after MAT compared with those before surgery. [Conclusion] MAThas a good long-term clinical consequences, which does effectively improve knee joint function.
