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.
1. 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.
2. The method of claim 1 , wherein the first resected region is resected robotically, and wherein the first cutting tool is a planar cutting instrument.
3. The method of claim 2 , wherein the second resected region is resected robotically, and wherein the second cutting tool is a rotating cutting instrument.
4. The method of claim 1 , wherein the first resected region is resected in a debulking pass, and wherein the second resected region is resected in a finishing pass.
5. The method of claim 1 , wherein the second resected region defines a plurality of channeled preparations.
6. The method of claim 1 , wherein the second resected region defines a cross-section with peaks and valleys created by burring the bone.
7. The method of claim 1 , wherein the first cutting tool follows a first resection path including movement in a first linear direction, and wherein the second cutting tool follows a resection path in both the first linear direction and a second linear direction perpendicular to the first linear direction.
8. The method of claim 1 , wherein the first cutting tool is a saw and the second cutting tool is a burr, and the saw and the burr are adapted to interchangeably connect to a robotic arm.
9. A method of preparing a bone of a patient to receive a prosthetic implant thereon, the method comprising:
robotically resecting the bone of the patient with a first cutting tool to create a first resected region;
robotically 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 is resected in a debulking pass, and wherein the second resected region is resected in a finishing pass.
10. The method of claim 9 , wherein the first cutting tool is a planar cutting instrument.
11. The method of claim 10 , wherein the second cutting tool is a rotating cutting instrument.
12. The method of claim 9 , wherein the second resected region defines a plurality of channeled preparations.
13. The method of claim 9 , wherein the second resected region defines a cross-section with peaks and valleys created by burring the bone.
14. The method of claim 9 , wherein the first cutting tool follows a first resection path including movement in a first linear direction, and wherein the second cutting tool follows a resection path in both the first linear direction and a second linear direction perpendicular to the first linear direction.
15. The method of claim 9 , wherein the first cutting tool is a saw and the second cutting tool is a burr, and the saw and the burr are adapted to interchangeably connect to a robotic arm.
16. The method of claim 9 , wherein the first resection region has a first geometry and the second resected region has a second geometry different than the first geometry.
17. 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;
robotically 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 second resected region defines a plurality of channeled preparations.
18. The method of claim 1 , wherein the first cutting tool is a planar cutting instrument and the second cutting tool is a rotating cutting instrument.
