Abstract
A robotic system for preparing a bone to receive a prosthetic device. The robotic system includes a controllable guide structure configured to guide cutting of the bone into a shape for receiving the prosthetic device, and a computer readable medium for storing data representative of the prosthetic device. The prosthetic device includes a body portion having an implantation surface configured to face the bone upon implantation and at least one feature that provides a constraint structure that will constrain the prosthetic device in the bone. The robotic system includes a control system for controlling the guide structure, and is configured to define at least one bone-cutting pattern for (i) removing a first portion of bone in a first area sufficient to seat the body portion and (ii) at least one of removing and maintaining a second portion of bone in a second area configured to interact with the constraint structure.
