Fig. 5From: The patient with patellar instability has a stenotic intercondylar notch and a thin anterior cruciate ligament: a retrospective comparative studyMeasurements of the ACL in the sagittal a–c and axial d planes. The inclination angle a was formed between the line perpendicular to the anatomical axis of the tibia and the most anterior fibers of the ACL. The ACL length b was the distance between the tibial midpoint and the femoral midpoint of the ACL attachments. The maximal anteroposterior thickness of the ACL c was evaluated at the outlet of the intercondylar notch on the sagittal view. The maximal transverse width d was evaluated on the axial view showing the widest ACL. ACL Anterior cruciate ligamentBack to article page
