The efficacy of meniscus posterior root tears repair: A systematic review and meta-analysis

Abstract

Purpose: To report of efficacy repair treatment for meniscus posterior root tears repair. Methods: We systematically searched databases including PubMed, Embase, and Cochrane Library for relevant articles. Coleman Methodology Score was used for a quality assessment of the included studies. A meta-analysis was performed to analyze for efficacy of MMPRTs repair. Results: Twenty-two studies, 14 level III and 8 level IV, were included in this systematic review, with a total of 926 cases. Studies comparing repair with either meniscectomy or conservative treatment found greater improvement and slower progression of Kellgrene–Lawrence grade with meniscal repair. Decreased meniscus extrusion is beneficial to the prognosis of patients undergoing MMPRTs repair. As treatment efficacy, the Lysholm score increased 28.87 (P < 0.001), IKDC score increased 31.73. The overall pooled event rates of progression of K-L grade is 0.200. Difference of Lysholm score and IKDC score between repair and meniscectomy were 8.72 and 9.67. Conclusions: The clinical subjective score after MMPRT repair was significantly improved compared with the preoperative status. Considering the progression of joint K-L grade, it can prevent the progression of arthrosis to some extent, but not completely. Decreased meniscus extrusion is beneficial to the prognosis of patients undergoing MMPRTs repair. Based on these results, MMPRTs repair cloud result favorable outcomes.
