Patient-Adapted and Improved Articular Implants, Designs and Related Guide Tools

摘要

Methods and devices are disclosed relating improved articular models, implant components, and related guide tools and procedures. In addition, methods and devices are disclosed relating articular models, implant components, and/or related guide tools and procedures that include one or more features derived from patient-data, for example, images of the patient's joint. The data can be used to create a model for analyzing a patient's joint and to devise and evaluate a course of corrective action. The data also can be used to create patient-adapted implant components and related tools and procedures.

主权项

1. A femoral implant for replacing a knee joint of a patient comprising:
a. a medial condyle having a medial articular surface that includes a medial sagittal curve derived from a corresponding medial condyle of the knee joint of the patient; b. a lateral condyle having a lateral articular surface that includes a lateral sagittal curve derived from a corresponding lateral condyle of the knee joint of the patient; and c. a trochlear portion having a trochlear articular surface that includes a trochlear sagittal curve derived from the trochlear region of the knee joint of the patient, wherein the medial, lateral and trochlear sagittal curves are substantially J-curves derived from the corresponding, respective medial, lateral and trochlear J-curves of the knee joint of patient.
