摘　　要：Introduction: Femoral and tibial morphology posted as anatomical risk factors for ACL injuries. Samora et.al found out that a decreased BIA was associated with ACL rupture. Alentorn-Geli et al. found that the angle between the Blumensaat line and the anterior tibial slope (BATS angle) was significantly greater in men with ACL injury. However, other authors were not able to reproduce the similar findings. Our study aimed to determine the Blumensaat inclination angle (BIA) and angle between Blumensaat line and tibial slope (BATS) in patients with or without anterior cruciate ligament injury. We also explored the factors influence them. Method: We elavuated 142 MRI knee done in Hospital Sultan Ismail from January 2017 to November 2020. Study group was patient with ACL injuries, with or without meniscus and cartilage injuries. Control group was patient with no ACL injuries. 57 patients with history of fracture around the knee joint, multiligamentous injuries, inflammatory arthritis and tumour were excluded from the study. We recorded their age, gender, BIA, and BATS angle. BIA and BATS angle were measured in sagittal plane MRI as described by Koji Iswasaki et al. and Alentorn-Geli et al. Result: 54 patients were in study group and 31 years in control group. The mean age for study group was 32.7 (8.95) year old, and for control group was 42.5 (14.54). The mean BIA for study group was 36.20 (4.542) degree, and control group was 37.25 (4.941). The mean BATS for study group was 36.33 (5.78) degree, and control group was 25.26 (6.047) degree. BIA and BATS angle did not differ in both groups, age and gender. Conclusion: Our study did not show BIA and BATS angle as an anatomical risk factor for ACL injuries. Age and gender did not affect these angles.Introduction: Femoral and tibial morphology posted as anatomical risk factors for ACL injuries.
