The co-occurrence of anterior cruciate ligament (ACL) rupture with medial collateral ligament (MCL) rupture is a compound injury that can be associated with meniscal tears.
To report the characteristics of meniscal tears in knees with isolated ACL versus combined ACL and MCL injuries, analyzing their frequency, distribution by site, and lesion type.
Cross-sectional study; Level of evidence, 3.
This prospective, multicenter, case-control study, conducted across 10 hospitals in France as part of a symposium of the national French Society of Arthroscopy, compared patients undergoing ACL reconstruction with and without MCL injury. The 2 groups were matched by sex, age (±3 years), and body mass index (±3) to minimize imbalances between groups. All operations were performed by senior surgeons, who systematically explored for ramp, root, and other types of meniscal lesions as well as corner injuries. The primary outcome focused on meniscal injury frequency, with secondary outcomes examining lesion sites and types. A subgroup analysis was performed to compare these outcomes depending on the injury chronicity. Acute ACL injuries were those treated within 3 months of injury, and chronic lesions were those treated after this period.
A total of 722 patients were included, with a mean age of 30.32 ± 10.78 years. Meniscal injuries were observed more frequently in the ACL+MCL group, with 217 of 408 patients (53.2%) affected, compared with 130 of 314 patients (41.4%) in the isolated ACL group ( = .001). Lateral meniscal lesions were significantly more common in the ACL+MCL group at 41.9% compared with 20.8% in the isolated ACL group ( < .001). The same pattern was found independent of chronicity. Medial meniscal lesions were significantly more common in the isolated ACL group regardless of chronicity status. In terms of types of medial lesions, the ACL+MCL group primarily experienced longitudinal (45.9%) and ramp lesions (28.7%), whereas the isolated ACL group experienced mostly ramp lesion (58.3%; < .001). No significant difference was observed in the distribution of lateral meniscal injury types.
This study demonstrated a higher prevalence of meniscal injuries associated with ACL+MCL injuries compared with isolated ACL injuries, with lateral meniscal lesions particularly more frequent, independent of chronicity status.
前交叉韧带（ACL）断裂与内侧副韧带（MCL）断裂同时发生是一种复合损伤，可能伴有半月板撕裂。
报告孤立性ACL损伤与ACL和MCL联合损伤膝关节中半月板撕裂的特征，分析其发生率、部位分布和损伤类型。
横断面研究；证据等级，3级。
这项前瞻性、多中心、病例对照研究在法国10家医院进行，作为法国国家关节镜学会研讨会的一部分，比较了接受ACL重建术的有和没有MCL损伤的患者。两组在性别、年龄（±3岁）和体重指数（±3）方面进行匹配，以尽量减少组间不均衡。所有手术均由资深外科医生进行，他们系统地探查了半月板的斜坡、根部和其他类型的损伤以及角落损伤。主要结局关注半月板损伤的发生率，次要结局检查损伤部位和类型。根据损伤的慢性程度进行亚组分析以比较这些结局。急性ACL损伤是指在受伤后3个月内接受治疗的损伤，慢性损伤是指在此期间之后接受治疗的损伤。
共纳入722例患者，平均年龄为30.32±10.78岁。ACL+MCL组半月板损伤的发生率更高，408例患者中有217例（53.2%）受影响，而孤立性ACL组314例患者中有130例（41.4%）（P=.001）。ACL+MCL组外侧半月板损伤明显更常见，为41.9%，而孤立性ACL组为20.8%（P<.001）。无论慢性程度如何，均发现相同的模式。无论慢性程度如何，内侧半月板损伤在孤立性ACL组中明显更常见。就内侧损伤类型而言，ACL+MCL组主要为纵向损伤（45.9%）和斜坡损伤（28.7%），而孤立性ACL组主要为斜坡损伤（58.3%；P<.001）。外侧半月板损伤类型的分布未观察到显著差异。
本研究表明，与孤立性ACL损伤相比，ACL+MCL损伤相关的半月板损伤患病率更高，外侧半月板损伤尤其更频繁，且与慢性程度无关。
