Claim One:
1. A system for registering two dimensional image data to intra-operatively digitized landmarks obtained during a joint arthroplasty procedure on a patient having a joint in need of such a procedure comprising: a surgical navigation system capable of determining a position and an orientation of an object within a working volume, including a central processing unit, a display, a memory unit and a storage unit; a first circuit to import the two dimensional image data for the joint into the memory unit; a second circuit to perform an intra-operative anatomical survey of the joint and an associated limb to digitize selected landmarks and to determine a mechanical axis for the limb; a third circuit to register the two dimensional image data to the mechanical axis and display the registered two dimensional image data on the display; and a fourth circuit to assist in guiding a cutting jig into position within the joint based on the landmarks while showing the registered two dimensional image data in relation to the landmarks, wherein the position and the orientation of the cutting jig can be tracked by the surgical navigation system.
