Mean values are shown for (A) AP translation of the femur and (B) internal-external (IE) rotation of the tibia during passive knee flexion for the native knee and all four rotational alignments. The error bars represent one SD. A difference exists between the native condition and any of the four axes, but there is no difference in these kinematics based on rotational alignment alone. TA = transverse axis; MBA = medial border axis; MTA = medial third axis; TEA = transepicondylar axis.
