Anterior Cruciate Ligament

The knee should be positioned with 10°–15° of external rotation to bring the anterior cruciate ligament (ACL) into the sagittal plane. Alternatively, the same effect can be achieved by tilting of the imaging plane (sagittal oblique orientation). Specific queries regarding the area of the ACL may require a slice thickness of 3 mm. Sagittal (oblique), coronal, and axial imaging planes.
