Edge-Matched Articular Implant
A method of joint arthroplasty includes obtaining an image of at least a portion of the tibial plateau. An outer periphery of at least a portion of the tibial plateau is derived based, at least in part, on the image. An implant is provided for the tibial plateau, the implant having a periphery that includes an outer edge that substantially matches the derived outer periphery of the tibial plateau.
1 . A method of making an implant for repairing a joint of a patient, the method comprising:
obtaining electronic image data of the joint including at least a portion of a bone associated with the joint;
simulating a cut at a predetermined height using the electronic image data to create a simulated cut surface of the bone associated with the joint;
deriving an outer periphery of the simulated cut surface; and
designing an implant having an outer periphery, at least a portion of which is configured to match at least a portion of the derived outer periphery of the simulated cut surface of the bone associated with the joint and to rest on or to be adjacent to cortical bone of the simulated cut surface of the bone associated with the joint.
2 . The method of claim 1 , wherein simulating the cut includes determining a height of the cut based on a reference point or a landmark of the joint of the patient.
3 . The method of claim 1 , further including simulating the cut at a predetermined orientation relative to one or more biomechanical or anatomical axes of the joint.
4 . The method of claim 1 , further including determining one or more biomechanical or anatomical axes of the joint with the electronic image data and/or additional image data.
5 . The method of claim 1 , wherein the joint of the patient is a knee.
6 . The method of claim 1 , wherein the joint of the patient is a hip.
7 . The method of claim 1 , wherein the joint of the patient is an ankle.
8 . The method of claim 1 , wherein the joint of the patient is a joint of the foot.
9 . The method of claim 1 , wherein the joint of the patient is a shoulder.
10 . The method of claim 1 , wherein the joint of the patient is an elbow.
11 . The method of claim 1 , wherein the joint of the patient is a wrist.
12 . The method of claim 1 , wherein the joint of the patient is a joint of the hand.
