Any deviation in femoral rotation from a neutral position is transformed, degree for degree, to an error in calculated femoral torsion. However, true femoral rotation can be determined accurately from one lateral roentgenogram of the femoral condyles if the angle between the X-ray beam and the femoral axis is known. With the aid of the data presented, the cross-table lateral roentgenogram of the femoral condyles provides an accurate and reproducible means of verifying true femoral position.
