Objectives: We aimed to determine the relationship between medial and lateral anterior tibial translation (ATT) and anterior cruciate ligament (ACL) injury. Methods: This cross-sectional study analyzed 312 patients who underwent knee magnetic resonance imaging (MRI) with a prediagnosis of ACL rupture between January 2018 and December 2018. 33 patients were excluded from the study. The ATT of both medial and lateral compartments was measured on T1-weighted sagittal images. All MRI images were evaluated by a musculoskeletal radiologist and an orthopedic surgeon. Mid-sagittal planes were used to assess the ATT in both the medial and lateral compartments. Results: The interclass correlation coefficient (ICC) values for medial and lateral ATT were 0.999 and 0.997, respectively. There was a significant statistical difference between ACL-ruptured and non-ruptured groups according to medial and lateral ATT measurements (p<0.001). The difference between sexes for medial ATT values was significant (p=0.004). ROC analysis showed that a lateral ATT value of 4.195 mm indicated a sensitivity of 0.726 and a specificity of 0.31. Conclusion: As a result of an ACL injury, ATT occurs in both the medial and lateral compartments. The agreement between readers regarding medial ATT and lateral ATT measurements was almost perfect. Static MR images may also be useful in the interpretation of secondary signs of ACL rupture. Keywords: Anterior cruciate ligament, anterior tibial translation, knee
