    摘要： 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 posterior cam of the femoral component may include a concave cam surface and a convex cam surface.

    摘要： A posterior stabilized knee orthopaedic prosthesis assembly includes a tibial bearing, a primary femoral component, and a revision femoral component. Each of the primary and revision femoral components is configured to separately articulate with the tibial bearing. However, each of the primary and revision femoral components has different geometry. The primary femoral component includes a posterior cam having a posterior cam surfacing including a concave cam surface and a convex cam surface. The revision femoral component includes a posterior cam having only a convex cam surface.

    摘要： An implantable orthopaedic knee prosthesis includes a femoral component including an articular surface configured to engage a tibial bearing and a laterally-angled trochlear groove defined in the articular surface. The trochlear groove of the femoral component is configured to receive a patella component in a first location at a first degree of flexion and a second location at a second degree of flexion. The second degree of flexion is greater than the first degree of flexion. An arced imaginary line defines a central section of the trochlear groove. When the femoral component is viewed in a first coronal plane extending through the first location, the arced imaginary line has a first radius of curvature. When the femoral component is viewed in a second coronal plane extending through the second location, the arced imaginary line has a second radius of curvature that is less than the first radius of curvature.
