Lateral meniscus posterior root tears (LMPRTs) are commonly found in patients with anterior cruciate ligament (ACL) injuries. However, risk factors for LMPRTs are not well known. This study was designed to systematically review the available evidence regarding risk factors associated with LMPRTs.
The PubMed, EMBASE, Cochrane Library, and Web of Science databases were searched for papers containing the key words "lateral meniscus posterior root tears", "LMPRTs" and "risk factor". Inclusion screening, data extraction, and quality assessment of the included articles were conducted independently by two authors. Statistical analysis was conducted to determine risk factors for LMPRTs.
Seventeen studies with a total sample size of 6, 589 patients were identified. The pooled prevalence of LMPRTs was 9.6% (range, 5.1-33.8%) for ACL injury. Significant risk factors included a patient age of < 30 [OR = 1.4, 95% CI (1.07, 1.84), p = 0.01], male sex [OR = 1.50, 95% CI (1.24,1.81), p = 0.01], higher body mass index (BMI) [MD = 0.45, 95% CI (0.13, 0.76), p < 0.01], higher lateral posterior tibial slope (LPTS) [MD = 2.22, 95% CI (1.37, 3.07), p < 0.01], deep sulcus sign [OR = 5.76, 95% CI (1.35, 24.52), p < 0.01] and bone bruises on lateral femoral condyle [OR = 4.88, 95% CI (1.27, 18.77), p < 0.01], lateral meniscal extrusion > 1 mm [OR = 5.56, 95% CI (1.52, 20.29), p < 0.01] and > 3 mm [OR = 12.91 95% CI (1.28, 130.01), p < 0.01], medial meniscal tears [OR = 1.40, 95% CI (1.12, 1.75), p < 0.01], and medial ramp lesions [OR = 2.29, 95% CI (1.35, 3.89), p < 0.01].
Age below 30, male, higher BMI, higher LPTS, deep sulcus sign, bone bruises on lateral femoral condyle, lateral meniscal extrusion, medial meniscal tear, and medial ramp lesion are risk factors for LMPRTs.

外侧半月板后根部撕裂（LMPRTs）在 ACL 损伤患者中较为常见。然而，LMPRTs 的风险因素尚不清楚。本研究旨在系统地回顾与 LMPRTs 相关的风险因素的现有证据。
在 PubMed、EMBASE、Cochrane 图书馆和 Web of Science 数据库中检索包含关键词“外侧半月板后根部撕裂”、“LMPRTs”和“风险因素”的文献。两名作者独立进行纳入筛选、数据提取和纳入文献的质量评估。统计学分析用于确定 LMPRTs 的风险因素。
共确定了 17 项研究，总样本量为 6589 例患者。ACL 损伤的 LMPRTs 总患病率为 9.6%（范围为 5.1-33.8%）。显著的风险因素包括：患者年龄<30 岁[比值比（OR）=1.4，95%置信区间（CI）（1.07，1.84），p=0.01]、男性[OR=1.50，95%CI（1.24，1.81），p=0.01]、较高的体重指数（BMI）[MD=0.45，95%CI（0.13，0.76），p<0.01]、较高的外侧后胫骨倾斜度（LPTS）[MD=2.22，95%CI（1.37，3.07），p<0.01]、深沟征[OR=5.76，95%CI（1.35，24.52），p<0.01]和外侧股骨髁骨挫伤[OR=4.88，95%CI（1.27，18.77），p<0.01]、外侧半月板突出>1mm[OR=5.56，95%CI（1.52，20.29），p<0.01]和>3mm[OR=12.91，95%CI（1.28，130.01），p<0.01]、内侧半月板撕裂[OR=1.40，95%CI（1.12，1.75），p<0.01]和内侧斜坡病变[OR=2.29，95%CI（1.35，3.89），p<0.01]。
年龄<30 岁、男性、较高的 BMI、较高的 LPTS、深沟征、外侧股骨髁骨挫伤、外侧半月板突出、内侧半月板撕裂和内侧斜坡病变是 LMPRTs 的风险因素。
