Abstract

Systems and methods include a component of a bone implant that includes a patient specific bone contacting surface and, optionally, at least one protrusion adjacent to or extending from the patient specific bone contacting surface. The at least one protrusion is configured for engaging a bone preparation in the bone. To prepare the bone for receiving the component, one or more cutting tool templates may be used. The one or more cutting tool templates may be fabricated to have a patient specific bone contacting surface that engages the bone that is to receive the implant component. A cutting tool is engaged in one or more of one or more slots defined by the cutting tool template(s) to remove surface portions of the bone to create the bone preparation for engaging the protrusion. The patient specific bone contacting surface of the component engages the bone.
