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.
Claims41
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.

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.

- 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.

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.

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.

- placing a patient-specific surface of a surgical instrument on a corresponding surface portion of a femoral neck 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 a 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 femoral neck;
- resecting the femoral neck based at least in part on the location of the guide;
- and
- implanting a prosthesis based at least in part on the location of the resected tissue.

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 define a predetermined guide path relative to an axis of the hip extending through a femoral head of the patient, 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 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 the site of the removed tissue.
