Fig. 1 Sagittal image with the Blumensaat's line marking the roof of the intercondylar notch. The current reference cursor at the anterior outlet of the notch is represented by the beginning of the Blumensaat's line. MR details: sagittal 3D DESS with water excitation, slice thickness of 0.7mm, 16.3ms TR, 4.7ms TE, 25° flip angle, 14cm×14cm FOV; 384×307 pixels matrix; 185Hz/pixel bandwidth, 1 average, anterior/posterior phase encoding, acquisition time 10min 23s.

Fig. 2 Measurements of the femoral notch on an axial image. The notch depth is perpendicular to a line connecting the ventral articular surfaces of the medial and the lateral femur condyle. The notch width and the condylar width are parallel to that line at 2/3 of the notch depth. MR details: axial reformatted (MPR) images of SAG 3D DESS: slice thickness of 0.7mm, 16.3ms TR, 4.7ms TE, 25° flip angle, 14cm×14cm FOV; 384×307 pixels matrix; 185Hz/pixel bandwidth, 1 average, anterior/posterior phase encoding, acquisition time 10min 23s.

Fig. 3 Measurements of the femoral notch on a coronal image. The notch depth is perpendicular to a line connecting the ventral articular surfaces of the medial and the lateral femur condyle. The notch width and the condylar width are parallel to that line at 2/3 of the notch depth. MR details: coronal IW TSE (COR_IW_TSE), slice thickness of 3mm, 3850ms TR, 29ms TE, 180° FA, 14cm×14cm FOV; 384×307 pixels matrix; 352Hz/pixel bandwidth; acquisition time 3min 24s.
