Comparative analysis of 15° and 60° of knee flexion using micro-CT (A–F). The coronal view (A,D), sagittal view (B,E), and horizontal view (C,F) were analyzed for each angle to confirm morphological differences between the AM bundle (white arrowhead) and the PL bundle (red arrowhead) of the ACL. At 60 degrees of flexion, the gap between the AM bundle and the PL bundle gradually widened (Supplemental Video 2), becoming distinctly verified (indicated by the yellow arrow; D–F). The transverse ligament is denoted by the pink dotted line (pink asterisk; D,E). A anterior, AM anterior cruciate ligament-anteromedial bundle, LM lateral meniscus, MM medial meniscus, M medial, P posterior, PL anterior cruciate ligament-posterolateral bundle, S superior.
