Whereas there has been growing interest in surgical repair of posterior medial meniscus root tears (PMMRTs), our understanding of the medium- and long-term results of this procedure is still evolving.
To report midterm clinical outcomes from PMMRT repairs.
Systematic review.
A literature review for this systematic analysis was performed in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. We identified studies that reported the results of arthroscopic repair of PMMRTs. Functional and imaging outcomes were reviewed and summarized.
In total, 28 studies with a total of 994 patients (83% female) with an overall mean age of 57.1 were included in this review. Clinical outcomes (Lysholm, International Knee Documentation Committee, Hospital for Special Surgery, and Tegner scores) were improved at final follow-up in all studies. Of patients, 49% had radiographic progression of at least 1 grade in the Kellgren-Lawrence scale at a mean follow-up of 4.0 years in 11 studies. Cartilage degeneration had progressed at least 1 grade on magnetic resonance imaging scans in 23% of patients at a mean follow-up of 31.6 months in 4 studies.
PMMRT repairs provide a functional benefit with consistent improvements in clinical outcome scores. There is some evidence that PMMRT repair slows the progression of osteoarthritis but does not prevent it at midterm follow-up.
尽管对后内侧半月板根部撕裂（PMMRT）的手术修复越来越感兴趣，但我们对该手术的中远期结果的理解仍在不断发展。
报告 PMMRT 修复的中期临床结果。
系统回顾。
根据 PRISMA（系统评价和荟萃分析的首选报告项目）指南，对本次系统分析进行了文献回顾。我们确定了报告关节镜下 PMMRT 修复结果的研究。回顾并总结了功能和影像学结果。
共有 28 项研究纳入了 994 例患者（83%为女性），平均年龄为 57.1 岁。所有研究的最终随访时临床结果（Lysholm、国际膝关节文献委员会、特种外科医院和 Tegner 评分）均得到改善。在 11 项研究中，11 项研究中有 49%的患者在平均 4.0 年的随访中 Kellgren-Lawrence 分级至少增加了 1 级，有 23%的患者在 4 项研究中有 31.6 个月的平均随访中至少有 1 级的软骨退变。
PMMRT 修复可提供功能益处，并持续改善临床结果评分。有证据表明，PMMRT 修复可减缓骨关节炎的进展，但在中期随访中并不能预防其发生。
