First Claim
1. A method of preparing a bone surface to receive a prosthetic implant thereon, the prosthetic implant having an articular surface and a bone contacting surface, the method comprising:
- resecting the bone surface at a first location to create a first resected region having a first tolerance profile with a first cross-section having peaks and valleys;
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 such that the second cross-section has peaks further apart and valleys deeper than the peaks and valleys of the first cross-section; and
contacting the bone contacting surface of the prosthetic implant with the first resected region.

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.

10. A method of preparing a bone surface to receive a prosthetic implant thereon, the prosthetic implant having an articular surface and a bone contacting surface, the method comprising:
-
resecting the bone surface at an anterior aspect thereof to create a first resected region having a first tolerance profile with a first cross-section having peaks and valleys; resecting the bone surface at a posterior aspect thereof to create a second resected region having a second tolerance profile with a second cross-section having peaks further apart and valleys deeper than the peaks and valleys of the first cross-section such that the first cross-section is denser than the second cross-section; and contacting the bone contacting surface of the prosthetic implant with the first resected region. - View Dependent Claims (11, 12, 13, 14)

15. A method of preparing a bone surface to receive a prosthetic implant thereon, the prosthetic implant having an articular surface and a bone contacting surface, the method comprising:
-
resecting the bone surface at a peripheral region thereof to create a first resected region having a first tolerance profile with a first cross-section having peaks and valleys; resecting the bone surface at an anterior region thereof to create a second resected region having a second tolerance profile with a second cross-section having peaks further apart and valleys deeper than the peaks and valleys of the first cross-section such that the first cross-section is denser than the second cross-section; and contacting the bone contacting surface of the prosthetic implant with the first resected region. - View Dependent Claims (16, 17, 18, 19)
