Abstract Objective To determine relationships of the femoral intercondylar angle and tibial plateau slope with anterior cruciate ligament injury.Methods From January 2014 to June 2015,thirty-four patients with ACL-injured (case group) and ACL-intact (control group) in each group were researched retrospectively.The medial tibial plateau slope (MTPS),lateral tibial plateau slope (LTPS),and femoral intercondylar angle (FIA) was measured on MR images.The data were compared between different genders and groups.Logistic regression analysis was performed to determine the influence of the anatomic factors on ACL status (injured or intact).Results No significant differences in the mean values of FIA,MTPS and LTPS were found between male and female patients.The FIA in the case group was significantly smaller than that in control group (P=0.021).LTPS in the case group was significantly higher than the control (P=0.004).There were significant different in FIA,LTPS and ACL (P=0.025,P=0.002).Logist regression model of merging probability showed that AUC=0.764.Conclusion The femoral intercondylar angle and the lateral tibial plateau slope are risk factors of ACL injury.It can be more accurate to predict the ACL injury by united FIA and LTPS.
