    摘要： A patella drill guide includes a base with a flat patella bone-facing surface, a drill guide bore extending through the base, a cantilever spring member and a bone-gripping member. The cantilever spring member biases the bone-gripping member and the flat patella bone-facing surface toward each other. Flexing the cantilever spring member moves the bone-gripping member away from the flat patella bone-facing surface so that the drill guide can be placed on the patella. When the cantilever spring member is released, the patella is clamped between the bone-gripping member and the flat patella bone-facing surface. The drill guide may have sizing indicia and may be part of a kit including trial components to be mounted to the drill guide.

    摘要： An orthopaedic knee prosthesis assembly includes a plurality of femoral components. Each component includes a medial condyle and a lateral condyle. When each component is viewed in a coronal plane extending through a distal-most point of the medial condyle and a distal-most point of the lateral condyle, the medial condyle has a medial curved distal-most surface that includes the distal-most point, and a width is defined between the distal-most points of the medial condyle and the lateral condyle. The coronal radius of the distal-most surface of a first component is proportionally greater than the coronal radius of a second component. The coronal radius of the second component is proportionally greater than the coronal radius of a third component. The first component width is proportionally greater than the second component width, and the second component is proportionally greater than the width of the third component.

    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.
