Abstract 【Objective】 To construct a risk model for anterior lateral ligament (ALL) injury in individuals with high body mass index (BMI) and to validate it. 【Methods】 The clinical data of 110 patients with non-contact anterior cruciate ligament (ACL) rupture in the Department of Orthopedics ward Ⅲ of our hospital from January 2022 to December 2024 were retrospectively analyzed. Among them, patients with simple ACL rupture were set as the control group (n=60), and those with concomitant ALL injury in addition to ACL were set as the observation group (n=50). Multivariate Logistic regression analysis was used to determine the independent risk factors for ALL injury in high BMI individuals, and a nomogram model was established based on this. The calibration curve and receiver operating characteristic (ROC) curve were used to validate the model. 【Results】 The results of multivariate Logistic regression analysis showed that meniscal injury, multiple sprains, history of re-injury, large posterior tibial plateau inclination angle on the lateral side, and large posterior meniscal inclination angle on the lateral side were all risk factors for ALL injury in high BMI individuals (P<0.05); The calibration curve of the model showed good consistency between predicted probability and actual observation results. The ROC curve analysis results showed that the model had high diagnostic accuracy, with an area under the curve (AUC) value of 0.983, a sensitivity of 92.0%, and a specificity of 100%. 【Conclusion】 The risk model for ALL injury in high BMI individuals has a high predictive value for ALL injury in high BMI individuals, which can help clinicians identify high-risk patients early and make appropriate treatment decisions.
