Abstract
Official abstract text for this publication.
Disclosed herein are tools for repairing articular surfaces repair materials and for repairing an articular surface. 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.
First claim
Opening claim text (preview).
What is claimed is: 1. A patient-specific patellar template configured to facilitate the placement of a patella implant in repairing a knee joint of a patient comprising: a patient-specific contact surface for engaging at least a portion of an articular surface of the patella of the knee joint, the patient-specific contact surface including anatomical information derived from image data of the knee joint of the patient; and at least one guide for directing movement of a surgical instrument. 2. The patient-specific patellar template of claim 1 , wherein the anatomical information includes articular shape information of the patella of the knee joint of the patient. 3. The patient-specific patellar template of claim 1 , wherein the patient-specific contact surface has a shape that negatively matches a shape of at least a portion of the patella of the knee joint of the patient. 4. The patient-specific patellar template of claim 1 , wherein the patient-specific contact surface has a shape that negatively matches a cartilage shape of at least a portion of the patella of the knee joint of the patient. 5. The patient-specific patellar template of claim 1 , wherein the patient-specific contact surface has a shape that negatively matches a subchondral bone shape of at least a portion of the patella of the knee joint of the patient. 6. The patient-specific patellar template of claim 1 , wherein the surgical instrument is a surgical saw, drill or reamer. 7. An articular repair system for repairing a knee joint of a patient comprising: the patient-specific patellar template of claim 1 , and a patellar implant. 8. The articular repair system of claim 7 , wherein the patellar implant is configured based on electronic image data of the knee joint of the patient. 9. The articular repair system of claim 7 , wherein the patellar implant is selected from preexisting systems. 10. The articular repair system of claim 9 , wherein the selected patellar implant is further shaped based on electronic image data of the knee joint of the patient.
