1. A method of designing an orthopaedic implant, comprising the steps of:
- (a) obtaining three dimensional data corresponding to a multi-piece existing or prototype orthopaedic implant;
(b) obtaining three dimensional data sets for a first bone and a second bone cooperating to form a joint;
(c) associating the three dimensional data corresponding to the multi-piece existing or prototype orthopaedic implant with a three dimensional data set for the first bone and the second bone to comprise a virtual joint replacement;
(d) taking the virtual joint replacement through a virtual range of motion and recording kinematic data; and
(e) responsive to the recorded kinematic data, modifying the existing or prototype orthopaedic implant.

Abstract
A method for anatomical analysis and joint implant design. Embodiments provide users with the ability to anatomically analyze a single bone or a series of bones that exist in a database, evaluate surgical landmarks and axes, identify differences among specific characteristics of a given population, and modify existing implants or create new implant designs based on anatomical analyzes.

4. A method of designing an orthopaedic implant, comprising the steps of:
-
(a) obtaining three dimensional data sets for a first bone and a second bone cooperating to form a joint of a mammal; (b) moving the first bone with respect to the second bone through a virtual range of motion of the joint to establish natural kinematic data; (c) repeating steps (a) and (b) for different animals of the same mammal; (d) mathematically modeling the natural kinematic data; and (e) designing a multi-piece existing or prototype orthopaedic implant using the mathematically modeled natural kinematic data.

5. A method of designing an orthopaedic implant, comprising the steps of:
-
(a) obtaining three dimensional data sets for a first bone cooperating with a second bone to form a joint of a mammal, where the three dimensional data sets include an individual data set for multiple samples of the first bone; (b) propagating a standard reference point across each individual data set; (c) obtaining a three dimensional data set for an orthopaedic component adapted to be mounted to the first bone; (d) virtually mounting the orthopaedic component to the multiple samples of the first bone using the standard reference point to standardize the orthopaedic component across the multiple samples; (e) moving the first bone with respect to the second bone through a virtual range of motion of the joint to generate kinematic data; and (f) modifying the design of the orthopaedic implant using the generated kinematic data. - View Dependent Claims (6, 7, 8, 9, 10)
