1. A method of determining the rotational alignment axis of bone joints involving a first and a second bone, comprising:

  • tracking the position of a third bone with reference to the first or the second bone;

    obtaining a trajectory of the third bone, wherein the trajectory is generated by the movement of the bone joint; and

    calculating an axis of alignment of the first or second bone at the joint using the relative movement of the third bone with reference to either the first or the second bone.
