Abstract: A system for implanting a prosthetic device includes a first component of the prosthetic device configured to be disposed in an actual joint and including a first feature. The system further includes a processing circuit configured to determine, based in part on a second component of the prosthetic device that is disposed on an actual bone of the actual joint, a placement of the first component on the same actual bone to obtain a desired relationship between the first component and the second component. The processing circuit is further configured to determine a relationship between the first component and the second component. The second component includes a second feature, and the determined relationship is based at least in part on the first feature and the second feature, and at least one of the first feature and the second feature includes a characteristic that is represented as a virtual feature.

Abstract: 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.
