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

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 knee replacement system for implantation in a knee joint of a patient, comprising:
a knee replacement implant including a femoral implant for implantation on a femur of the patient and a tibial implant for implantation on a tibia of the patient, the femoral implant including a lateral condyle portion having a curved condylar shape and having a lateral bearing surface configured to articulate with the tibial implant when the tibial and femoral implants are implanted in the knee joint of the patient and an inner surface configured to abut one or more bone cut surfaces of a femur when the femoral implant is implanted in the knee joint of the patient, and the tibial implant including a bearing surface configured to articulate with the lateral bearing surface of the femoral implant when the tibial and femoral implants are implanted in the knee joint of the patient, and a bone-facing surface configured to abut a surface of a tibia of the patient when the tibial implant is implanted in the knee joint of the patient, wherein the lateral condyle portion has a narrowed posterior portion, such that the width of the lateral condyle portion measured in substantially the mediolateral direction narrows in a posterior part of the lateral condylar portion.
