Implants for altering wear patterns of articular surfaces
View Patent ↗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.
