20140142713 | KNEE PROSTHESIS ASSEMBLY HAVING PROPORTIONAL TROCHLEAR GROOVE GEOMETRY - 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. | 05-22-2014 |
20140142714 | KNEE PROSTHESIS ASSEMBLY HAVING PROPORTIONAL CORONAL GEOMETRY - 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. | 05-22-2014 |
