A prosthetic device includes one or more components configured to be
disposed in a joint. The component includes at least one feature
configured to provide information about the component. The information
can be used to determine or create the relationship between the component
and the joint and/or other components. This relationship may be used to
evaluate and/or modify the expected performance of the prosthetic device
and assist in determining the optimal relationship between one or more
components and a patient's anatomy.
