Abstract

Disclosed herein are systems and methods for bone preparation with designed areas having accurate tolerance profiles to enable improved initial fixation and stability for cementless implants and to improve long-term bone ingrowth/ongrowth to an implant. A method of preparing a bone surface to receive a prosthetic implant thereon having an articular surface and a bone contacting surface includes resecting the bone surface at a first location to create a first resected region having a first tolerance profile with a first cross-section, resecting the bone surface at a second location to create a second resected region having a second tolerance profile with a second cross-section less dense than the first cross-section, and contacting the bone contacting surface of the prosthetic implant with the first resected region.

Dependent claims

A method of preparing a bone of a patient to receive a prosthetic implant thereon, the method comprising:

resecting the bone of the patient with a first cutting tool to create a first resected region;
resecting the bone of the patient with a second cutting tool to create a second resected region located at least partially within the first resected region;
and
contacting respective first and second surfaces of a bone contacting surface of the prosthetic implant with the first and second resected regions of the bone surface,
wherein the first resected region has a first geometry and the second resected region has a second geometry different than the first geometry.
