Figure 3.

A femoral model with a banking angle of 93.66 degrees. In the sagittal plane (right side), seven points, which were distributed equally on the projected centerline of the canal, were manually selected between the lesser trochanter and the flare of the condyles, which divided the centerline of the canal into three sections, including the proximal third, middle third, and distal third. The radii of circles (A), (B), and (C) fitted from the proximal, middle, and distal sections of the canal centerline were 1,077.79, 887.93, and 852.98 mm, respectively.
