The relationship between ramp lesion (RL), tibial slope (TS), and meniscal slope (MS) remains inadequately explored. This study aims to investigate whether TS and MS are predictive factors for anterior cruciate ligament (ACL) injuries associated with RL, and to evaluate the performance of TS and MS in predicting RL, including determining optimal cut-off values. A retrospective cohort study was conducted on 253 patients who underwent ACL reconstruction. Magnetic resonance imaging was used to measure TS and MS on tibial plateaus. Logistic regression analyses determined associations between TS, MS, and RL. Receiver operating characteristic (ROC) curves evaluated predictive performance and cut-off values. A total of 65 cases (25.7%) were found to have RL. Significant differences in causes of injury, medial TS (MTS), medial MS (MMS), and bone bruises were observed between groups. In the unadjusted model and adjusted models, they showed significant (P < 0.001) associations for MTS (1.73-1.75) and MMS (OR range = 2.14-2.24). The AUC for MTS was 0.72 (95% CI 0.65-0.79, P < 0.001) with a cut-off value of 6.73°, for MMS was 0.80 (95% CI 0.74-0.86, P < 0.001) with a cut-off value of 4.03°, indicating good predictive performance. Larger MTS and MMS are significant predictive factors for RL in patients with ACL injury. Clinicians should closely monitor ACL injury patients with elevated MTS or MMS. Utilizing MTS or MMS as a predictive parameter shows promise for the identification of RL.
斜坡损伤（RL）、胫骨坡度（TS）和半月板坡度（MS）之间的关系尚未得到充分研究。本研究旨在探讨TS和MS是否为与RL相关的前交叉韧带（ACL）损伤的预测因素，并评估TS和MS在预测RL方面的表现，包括确定最佳临界值。对253例行ACL重建的患者进行了一项回顾性队列研究。采用磁共振成像测量胫骨平台的TS和MS。逻辑回归分析确定TS、MS与RL之间的关联。受试者操作特征（ROC）曲线评估预测性能和临界值。共发现65例（25.7%）存在RL。两组在损伤原因、内侧TS（MTS）、内侧MS（MMS）和骨挫伤方面存在显著差异。在未调整模型和调整模型中，MTS（1.73 - 1.75）和MMS（OR范围 = 2.14 - 2.24）显示出显著（P < 0.001）关联。MTS的AUC为0.72（95%CI 0.65 - 0.79，P < 0.001），临界值为6.73°；MMS的AUC为0.80（95%CI 0.74 - 0.86，P < 0.001），临界值为4.03°，表明具有良好的预测性能。较大的MTS和MMS是ACL损伤患者发生RL的重要预测因素。临床医生应密切监测MTS或MMS升高的ACL损伤患者。将MTS或MMS用作预测参数在识别RL方面显示出前景。
