This study assessed the relationship between body mass index (BMI), anterior cruciate ligament (ACL) injury, and associated meniscal and cartilage injury. Age, ACL classification, and Tegner activity score were considered. A total of 1968 ACL reconstruction patients (2/1/1996 to 5/1/2012) were analyzed. All graft types, age groups, and activity levels were included. A BMI ≥30 correlated with a significant likelihood of medial meniscus tears (p = .022). Patients with a BMI ≥30 were 21.6% more likely to have a medial meniscus tear with an ACL injury. Grade III and IV chondral lesions correlated with a BMI ≥30 (p = .029). Patient's age predicted medial meniscus outcome (p = .013). Patients whose age was >25 had a 25.7% higher risk of medial meniscus tear. Chronic ACL patients were 52.6% more likely to have a meniscus injury. BMI, age, Tegner activity score, and ACL classification are good predictors of medial meniscus injury. Patients with a BMI ≥30 exhibit a greater risk of medial meniscus tear with ACL instability; however, BMI does not significantly contribute to increased chondral damage in ACL-deficient patients.
本研究评估了体重指数（BMI）、前交叉韧带（ACL）损伤以及相关半月板和软骨损伤之间的关系。研究考虑了年龄、ACL分类和Tegner活动评分。共分析了1968例ACL重建患者（从1996年2月1日至2012年5月1日）。纳入了所有移植物类型、年龄组和活动水平。BMI≥30与内侧半月板撕裂的显著可能性相关（p = 0.022）。BMI≥30的患者在ACL损伤时发生内侧半月板撕裂的可能性要高21.6%。III级和IV级软骨损伤与BMI≥30相关（p = 0.029）。患者年龄可预测内侧半月板的转归（p = 0.013）。年龄>25岁的患者发生内侧半月板撕裂的风险高25.7%。慢性ACL患者发生半月板损伤可能性要高52.6%。BMI、年龄、Tegner活动评分和ACL分类是内侧半月板损伤的良好预测指标。BMI≥30的患者在ACL不稳定时发生内侧半月板撕裂的风险更高；然而，BMI对ACL缺失患者软骨损伤增加并无显著影响。
