Abstract

Disclosed herein are methods, compositions and tools for repairing articular surfaces repair materials and for repairing an articular surface. The articular surface repairs are customizable or highly selectable by patient and geared toward providing optimal fit and function. The surgical tools are designed to be customizable or highly selectable by patient to increase the speed, accuracy and simplicity of performing total or partial arthroplasty.

First claim

What is claimed is:

1. A method of surgically repairing, replacing or resurfacing a hip joint of a patient, comprising:
placing a patient-specific surface of a surgical instrument on a corresponding surface portion of a hip joint of a patient to define a predetermined guide path relative to an axis of the hip joint extending through a femoral neck of the hip joint of the patient, wherein at least a portion of the patient-specific surface has a shape that substantially matches a shape of the corresponding surface portion of the hip joint and the patient-specific surface and a position and/or orientation of the guide path are each configured based at least in part on image data of the hip joint of the patient;
removing tissue along the guide path; and
implanting a prosthesis at a site associated with the removed tissue.

2. The method of claim 1 , wherein the guide path extends along at least a portion of the axis.

3. The method of claim 1 , wherein the guide path extends along at least a portion of a femoral neck axis.

4. A method of surgically repairing, replacing or resurfacing a hip joint of a patient, comprising:
placing a patient-specific surface of a surgical instrument on a corresponding cartilage surface portion of a hip joint of a patient to position a guide configured to provide a guide path in a predetermined location and/or orientation relative to the cartilage surface of the hip joint, wherein at least a portion of the patient-specific surface has a shape that substantially matches a shape of the corresponding cartilage surface portion of the hip joint and wherein the patient-specific surface and the location and/or orientation of the guide path are each configured based at least in part on image data of the hip joint of the patient;
using the guide to surgically alter the proximal femur by cutting, drilling or reaming tissue of the proximal end of the femur; and
implanting a prosthesis having a location based at least in part on the location of the cut, drilled or reamed tissue.

5. A method of surgically repairing, replacing or resurfacing a hip joint of a patient, comprising:
placing a patient-specific surface of a surgical instrument on a corresponding femoral surface portion of a hip joint of a patient to position a guide configured to provide a guide path in a predetermined location and/or orientation relative to the corresponding femoral surface of the hip joint, wherein at least a portion of the patient-specific surface has a shape that substantially matches a shape of the corresponding femoral surface portion of the hip joint and the patient-specific surface and the location and/or orientation of the guide path are each configured based at least in part on image data of the hip joint of the patient;
guiding a surgical tool with the guide to surgically alter tissue of the hip joint; and
orienting at least one component of a hip prosthesis based at least in part on the location of the guide.

6. The method of claim 5 , wherein the step of guiding a surgical tool to surgically alter tissue of the hip joint includes at least one of cutting, drilling and reaming the tissue.

7. The method of claim 5 , wherein the step of orienting at least one component of a hip prosthesis comprises establishing a predetermined anteversion of the at least one component.

8. The method of claim 5 , wherein the step of orienting at least one component of a hip prosthesis comprises establishing a predetermined retroversion of the at least one component.

9. The method of claim 5 , wherein the step of orienting at least one component of a hip prosthesis comprises establishing a predetermined rotation of the at least one component.

10. The method of claim 5 , wherein the step of orienting at least one component of a hip prosthesis comprises establishing a predetermined tilt of the at least one component.

11. The method of claim 5 , wherein the step of orienting at least one component of a hip prosthesis comprises orienting an acetabular component.

12. The method of claim 5 , wherein the step of orienting at least one component of a hip prosthesis comprises orienting an acetabular cup.

13. The method of claim 5 , wherein the step of orienting at least one component of a hip prosthesis comprises orienting a femoral component.

14. The method of claim 5 , wherein the step of orienting at least one component of a hip prosthesis comprises orienting a femoral head component.

15. A method of surgically repairing, replacing or resurfacing a hip joint of a patient, comprising:
placing a patient-specific surface of a surgical instrument on a corresponding surface portion of an acetabulum of a hip joint of a patient to position a guide configured to provide a guide path in a predetermined location and/or orientation relative to the acetabulum of the hip joint, wherein at least a portion of the patient-specific surface has a shape that substantially matches a shape of the corresponding surface portion of the acetabulum of the hip joint and the patient-specific surface and the location and/or orientation of the guide path are each configured based at least in part on image data of the hip joint of the patient, wherein the corresponding surface portion of the acetabulum of the hip joint includes a surface portion selected from the group consisting of: an acetabular wall surface portion, an acetabular rim surface portion; an acetabular fossa surface portion, and any combination thereof;
guiding a surgical tool with the guide to surgically alter tissue of the hip joint; and
implanting a hip joint prosthesis having a location based at least in part on the location of the surgically altered tissue.

16. The method of claim 15 , wherein the step of guiding a surgical tool to surgically alter tissue of the hip joint includes at least one of cutting, drilling and reaming the tissue.

17. The method of claim 15 , wherein the corresponding surface of the acetabulum includes at least a portion of a cartilage surface of the acetabulum.

18. The method of claim 15 , wherein the corresponding surface of the acetabulum includes at least a portion of a subchondral bone surface of the acetabulum.

19. The method of claim 15 , wherein the corresponding surface of the acetabulum includes at least a portion of a cortical bone surface of the acetabulum.

20. The method of claim 15 , wherein the corresponding surface of the acetabulum includes at least a portion of an osteophyte of the acetabulum.

21. A method of surgically repairing, replacing or resurfacing a hip joint of a patient, comprising:
placing a patient-specific surface of a surgical instrument on a corresponding surface portion of a proximal end of a femur of a hip joint of a patient to position a guide configured to provide a guide path in a predetermined location and/or orientation relative to the proximal end of the femur of the hip joint, wherein at least a portion of the patient-specific surface has a shape that substantially matches a shape of the corresponding surface portion of the proximal end of the femur of the hip joint and the patient-specific surface and the location and/or orientation of the guide path are each based at least in part on image data of the hip joint of the patient;
guiding a surgical tool with the guide to surgically alter tissue of the hip joint; and
implanting a hip joint prosthesis having a location based at least in part on the location of the surgically altered tissue.

22. The method of claim 21 , wherein the step of guiding a
