To evaluate the impact of the tibial slope on the severity and location of meniscal tears in patients presenting with anterior cruciate ligament (ACL) rupture.
We conducted a single-center retrospective observational study. We analyzed charts and records of patients who underwent ACL tear surgery between 2018 and 2021, excluding those with multiligamentous knee injuries or osteoarthritis. Posterior tibial slope was measured from lateral radiographs, and data on meniscal tears characteristics were collected, including laterality, anatomical location, blood supply zone, tear type, and treatment modality.
We included 749 patients (127 female, 622 male) who underwent ACL reconstruction (hamstring tendons, n = 59; bone-patellar tendon-bone, n = 659; quadriceps tendon, n = 31). Concomitant meniscal tears occurred in 361 patients (medial meniscus, 50.7%; lateral meniscus, 31.9%; both menisci, 17.4%). No correlation was found between posterior tibial slope and meniscal injury overall ( = .8). However, a significant correlation was noted between tibial slope and lateral meniscal body tear ( = .023).
Our findings suggest that an increased tibial slope, as measured on lateral radiographs, is not indicative of concomitant meniscal tears. However, in cases in which meniscal tears did occur in patients with a high posterior tibial slope, they predominantly affected the lateral meniscal body.

评估胫骨坡度对前交叉韧带（ACL）断裂患者半月板撕裂严重程度和位置的影响。
我们进行了一项单中心回顾性观察研究。分析了2018年至2021年间接受ACL撕裂手术患者的病历和记录，排除了多韧带膝关节损伤或骨关节炎患者。从外侧X线片测量胫骨后坡度，并收集半月板撕裂特征数据，包括侧别、解剖位置、血供区域、撕裂类型和治疗方式。
我们纳入了749例患者（女性127例，男性622例），他们接受了ACL重建（腘绳肌腱，n = 59；骨-髌腱-骨，n = 659；股四头肌肌腱，n = 31）。361例患者发生了合并半月板撕裂（内侧半月板，50.7%；外侧半月板，31.9%；双侧半月板，17.4%）。胫骨后坡度与总体半月板损伤之间未发现相关性（ = 0.8）。然而，胫骨坡度与外侧半月板体部撕裂之间存在显著相关性（ = 0.023）。
我们的研究结果表明，外侧X线片测量的胫骨坡度增加并不表明合并半月板撕裂。然而，在胫骨后坡度高的患者中发生半月板撕裂的情况下，它们主要影响外侧半月板体部。
