Implants for altering wear patterns of articular surfaces
First Claim
Patent Images
1. A method for designing an orthopedic device that alters a wear pattern on an articular surface of a joint of a patient, comprising:
- a) receiving image data associated with the joint of the patient;
b) determining a wear pattern of an articular surface of the joint of the patient at least in part from the image data; and
c) designing an orthopedic device based at least in part on the image data, wherein the orthopedic device is designed to alter the wear pattern of the articular surface to a revised wear pattern and configured to replace the articular surface of the joint of the patient.

42. A method for preparing a joint replacement implant for correcting an articular surface wear pattern of a patient'"'"'s joint, comprising:
-
a) obtaining electronic image data of an articular surface of the patient'"'"'s joint; b) analyzing the image data for the presence or absence of wear pattern indicia; c) determining a wear pattern from the wear pattern indicia; and d) providing an implant configured to replace the articular surface of the patient'"'"'s joint, wherein the implant has a characteristic topography for correcting the wear pattern to a revised wear pattern.

43. A method of creating an implant for use in joint arthroplasty to repair a patient'"'"'s joint, the method comprising:
-
a) obtaining electronic image data of an articular surface of the patient'"'"'s joint, the articular surface of the patient'"'"'s joint including a wear pattern; b) deriving a shape of the articular surface based, at least in part, on the image data; and c) providing an implant having a surface based on the shape of the articular surface and configured to replace the articular surface of the patient'"'"'s joint, wherein the implant is configured to alter the wear pattern of the joint to a revised wear pattern. - View Dependent Claims (44, 45, 46, 47, 48, 49)

50. A method for preparing an implant for accommodating an articular surface wear pattern of a femoral condyle and/or a tibial plateau of a patient'"'"'s knee joint, comprising:
-
a) obtaining electronic image data of an articular surface of the femoral condyle and/or tibial plateau; b) analyzing the image data for the presence or absence of wear pattern indicia; c) determining a wear pattern from the wear pattern indicia; and d) providing an implant having a surface with a characteristic topography for accommodating the wear pattern, wherein the implant is configured to replace at least a portion of the femoral condyle and/or the tibial plateau. - View Dependent Claims (51, 52)
