“…Some demographic risk factors including male sex, age, and body mass index (BMI) met the criteria for meta‐analyses. Fourteen included studies [1, 4, 10, 14, 15, 17, 22, 23, 25, 26, 28, 29, 31, 35] showed that the pooled OR of having LMPRT was 1.50 (95% CI, 1.24–1.81) in the male group compared with the female group (Fig. 2).…”

“…Preoperative MRI data including bone bruises on MRI, lateral meniscal extrusion, and concomitant meniscal tear were feasible for meta‐analyses. Five studies [1, 4, 15, 25, 31] demonstrated that deep sulcus sign [OR = 5.76, 95%CI (1.35, 24.52), p < 0.01] and bone bruises on the lateral femoral condyle [OR = 4.88, 95%CI (1.27, 18.77), p < 0.01] were associated with an increased risk of LMPRT. There were no significant differences between bone bruises on medial femoral condyle and lateral/medial tibia and LMPRTs (n.s.)…”

“…7). Five studies [8, 23, 25, 29, 30] found that a significantly more 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] were reported for those individuals with LMPRTs compared to the control group (Fig. 8).…”

“…At present, little is known about the risk factors for LMPRTs. Previous studies [1,2,4,8,10,14,15,17,22,23,25,26,[28][29][30][31]35] have reported that some risk factors were associated with an increased risk of LMPRTs, including higher body mass index (BMI), male sex, and increased posterior tibial slopes (PTS). However, some reports are controversial, and lack convincing and rigorous designs.…”

PurposeLateral 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. MethodsThe 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. ResultSeventeen 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]. ConclusionAge 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.
