1. A method of virtually assessing the fit of a prosthesis for placement on a resected bone surface, the method comprising the steps of:
- obtaining a three-dimensional contour of the resected bone surface;
creating a two-dimensional outline of the resected bone surface based on the three-dimensional contour of the resected bone surface;
creating a two-dimensional outline of a first prosthesis; and
comparing the two-dimensional outline of the resected bone surface with the two-dimensional outline of the first prosthesis.
