Kim SH, Park YB, Won YS, et al. - In this study, the radiological findings associated with ramp lesions in knees with anterior cruciate ligament (ACL) injury were ascertained. Between June 2011 and March 2019, the primary ACL reconstructions were included in the study. Researchers performed binary logistic regression analysis to investigate the risk factors such as age, gender, body mass index, medial tibial slope, mechanical axis angle, presence of Segond fracture, and lateral femoral condyle (LFC) ratio. The data indicated that in knees with an ACL injury, deep posterior LFC, varus alignment, and steep medial tibial slope were associated factors for ramp lesions. Careful evaluation and suspicion for ramp lesions should be considered in patients with an ACL injury who show the above-mentioned radiographic findings.
