To identify risk factors for posterior lateral meniscus root tears (PLRT) in patients with a tear of the anterior cruciate ligament (ACL).
A database of 268 patients undergoing primary ACL reconstruction between 2011 and 2013 was used to identify all patients with isolated ACL tears and patients with an associated PLRT. Patients with other concomitant injuries and patients who underwent surgery >6 months after the injury were excluded. Univariate analysis was performed by comparing the two groups with regard to gender, age, age groups (<30 vs. >30 years), height, weight, body mass index (BMI), BMI groups (<24.9, 25-29.9, and >30), type of injury (high-impact sports, low-impact sports, and not sports-related), and mechanism of injury (non-contact vs. contact). Multivariate logistic regression was carried out to identify independent risk factors for PLRT and to calculate odds ratios (ORs).
One-hundred and forty-two patients met the inclusion and exclusion criteria. Of those, 120 (85%) had an isolated ACL tear and 22 (15%) had an associated PLRT. No significant differences between patients with and without a PLRT were found for age, age groups, height, weight, BMI, BMI groups, and type of injury (p > 0.05). Univariate analysis revealed a statistically significant difference between both groups for gender distribution (p = 0.034) and mechanism of injury (p < 0.001), with male gender and a contact mechanism being more common in patients with PLRT. The sole independent risk factor for an associated PLRT identified in the multivariate logistic regression analysis was a contact mechanism with an OR of 17.52.
An associated PLRT is more common in male patients and patients who sustained a contact injury. Patients with a contact injury mechanism have an approximately 17-fold increased risk for a PLRT compared to patients with a non-contact injury. Special attention for this injury pattern is therefore necessary in those patients, and early referral to magnetic resonance imaging or arthroscopy is recommended.

确定前交叉韧带（ACL）撕裂患者后外侧半月板根部撕裂（PLRT）的危险因素。
使用2011年至2013年间接受初次ACL重建的268例患者的数据库，以识别所有孤立性ACL撕裂患者和伴有PLRT的患者。排除有其他合并伤的患者以及受伤后>6个月接受手术的患者。通过比较两组患者的性别、年龄、年龄组（<30岁与>30岁）、身高、体重、体重指数（BMI）、BMI组（<24.9、25 - 29.9和>30）、损伤类型（高冲击性运动、低冲击性运动和非运动相关）以及损伤机制（非接触与接触）进行单因素分析。进行多因素逻辑回归以确定PLRT的独立危险因素并计算比值比（OR）。
142例患者符合纳入和排除标准。其中，120例（85%）为孤立性ACL撕裂，22例（15%）伴有PLRT。有和没有PLRT的患者在年龄、年龄组、身高、体重、BMI、BMI组和损伤类型方面未发现显著差异（p>0.05）。单因素分析显示两组在性别分布（p = 0.034）和损伤机制（p<0.001）方面存在统计学显著差异，男性性别和接触机制在PLRT患者中更为常见。多因素逻辑回归分析中确定的伴有PLRT的唯一独立危险因素是接触机制，OR为17.52。
伴有PLRT在男性患者和遭受接触性损伤的患者中更为常见。与非接触性损伤患者相比，有接触性损伤机制的患者发生PLRT的风险增加约17倍。因此，对于这些患者，有必要特别关注这种损伤模式，建议早期转诊进行磁共振成像或关节镜检查。
