  • Posterior Cructiate-Retaining Orthopaedic Knee Prosthesis Having Controlled Condylar Curvature
    Publication number: 20120239158
    Abstract: An orthopaedic knee prosthesis includes a tibial bearing and a femoral component configured to articulate with the tibial bearing. The femoral component includes a condyle surface curved in the sagittal plane. The radius of curvature of the condyle surface decreases gradually between early-flexion and mid-flexion. Additionally, in some embodiments, the radius of curvature may be increased during mid-flexion.

  • Orthopaedic knee prosthesis having controlled condylar curvature
    Patent number: 8236061
    Abstract: An orthopaedic knee prosthesis includes a femoral component having a condyle surface. The condyle surface is defined by one or more radii of curvatures, which are controlled to reduce or delay the onset of anterior translation of the femoral component relative to a tibial bearing.

  • Posterior stabilized orthopaedic knee prosthesis having controlled condylar curvature
    Patent number: 8187335
    Abstract: An orthopaedic knee prosthesis includes a tibial bearing and a femoral component configured to articulate with the tibial bearing. The femoral component includes a posterior cam configured to contact a spine of the tibial bearing and a condyle surface curved in the sagittal plane. The radius of curvature of the condyle surface decreases gradually between early-flexion and mid-flexion. Additionally, in some embodiments, the radius of curvature of the condyle surface may be increased during mid-flexion.

  • FEMORAL COMPONENT OF A KNEE PROSTHESIS HAVING AN ANGLED CEMENT POCKET
    Publication number: 20120083894
    Abstract: An implantable orthopaedic knee prosthesis includes a femoral component that is configured to be coupled to a surgically-prepared distal femur. The femoral component has an articular side that includes a posterior femoral condyle surface. A fixation side is opposite the articular side, and it includes a posterior fixation surface that extends generally in the superior/inferior direction. The posterior fixation surface has an angled posterior cement pocket formed therein.

  • KNEE PROSTHESIS SYSTEM
    Publication number: 20110178605
    Abstract: A knee prosthesis system for total knee replacement procedures includes a plurality of distinctly-sized femoral components, a plurality of distinctly-sized fixed tibial components, a plurality of distinctly-sized mobile tibial components, a plurality of fixed inserts, and a plurality of mobile inserts. Each of the mobile inserts is sized and shaped such that each may be optimally matched to one of the femoral components and may be used with any one of the mobile tibial components. Each of the fixed inserts is sized and shaped such that each may be optimally matched to one of the femoral components and may be used with any one of the fixed tibial components.
