Implants for altering wear patterns of articular surfaces
Methods and devices for correcting wear pattern defects in joints. The methods and devices described herein allow for the restoration of correcting abnormal biomechanical loading conditions in a joint brought on by wear pattern defects, and also can, in embodiments, permit correction of proper kinematic movement.
1. An implant for correcting a wear pattern of an articular surface a joint of patient, comprising:
an implant body having a characteristic topography,
an interior surface, and
an outer surface,
wherein the characteristic topography is derived from a wear pattern of the articular surface and is configured to alter the wear pattern of the articular surface to a revised wear pattern, wherein the interior surface is configured to be placed at least in part on cartilage and/or subchondral bone of the joint.
2. The implant of claim 1 , wherein the revised wear pattern is configured to improve kinematics of the joint.
3. The implant of claim 1 , wherein the revised wear pattern is based, at least in part, on existing geometry of the joint of the patient.
4. The implant of claim 1 , wherein the revised wear pattern is based, at least in part, on kinematics of the joint of the patient.
5. The implant of claim 1 , wherein the revised wear pattern is based, at least in part, on wear patterns of a class of patients.
6. The implant of claim 1 , wherein the revised wear pattern is based, at least in part, on kinematics of a class of patients.
7. An implant for correcting a wear pattern of an articular surface a knee joint of a patient, comprising:
an implant body having a characteristic topography,
an interior surface, and
an outer surface,
wherein the characteristic topography is derived from a wear pattern of the articular surface and is configured to alter the wear pattern of the articular surface to a revised wear pattern, wherein the interior surface is configured to be placed at least in part on cartilage and/or subchondral bone of the knee joint.
8. The implant of claim 7 , wherein the revised wear pattern is configured to improve kinematics of the knee joint.
9. The implant of claim 7 , wherein the revised wear pattern is based, at least in part, on existing geometry of the knee joint of the patient.
10. The implant of claim 7 , wherein the revised wear pattern is based, at least in part, on kinematics of the knee joint of the patient.
11. The implant of claim 7 , wherein the revised wear pattern is based, at least in part, on wear patterns of a class of patients.
12. The implant of claim 7 , wherein the revised wear pattern is based, at least in part, on kinematics of a class of patients.
