  • Publication number: 20110125275
    Abstract: A prosthetic joint according to the present invention includes a first implant component for attachment to a first bone and a second implant component for attachment to a second bone. The first implant component has a condylar portion that includes first and second condylar bearing surfaces and similarly, the second implant component has bearing surfaces that receive and are complementary to the first and second condylar bearing surfaces. Each of the first and second condylar bearing surfaces and each of the bearing surfaces of the second implant component has a cross-section in a coronal plane that exhibits two different radii and a contact point is established between the first and second condylar bearing surfaces and the bearing surfaces of the second implant component. The bearing surfaces of the respective implant components are configured such that varus and valgus rotation of the first implant component relative to the second implant component causes the contact point to move outwardly.

  • Publication number: 20110125279
    Abstract: A knee joint prosthesis includes a femoral component having a first condylar bearing surface and a second condylar bearing surface. Each of the first and second condylar bearing surfaces has a cross-section in a coronal plane that exhibits at least two different radii. The prosthesis also includes a tibial component and an insert component associated with the tibial component. The insert component has bearing surfaces that are complementary to the first and second condylar bearing surfaces, wherein a contact point is established between the bearing surfaces of the insert component and the first and second condylar bearing surface. In accordance with the present invention and as a result of the above construction, varus and valgus rotation of the femoral component relative to the insert component causes the contact point to move laterally as the knee is rotated. By shifting the contact pointy laterally/outwardly, the knee stability (i.e., stiffness) gradually increased.
