Abstract:
1. A femoral component adapted to mount to a femur, the femur defining a mechanical axis and an anatomic axis, the component defining a component coordinate system having: a component transverse plane; a coronal plane perpendicular to said component transverse plane; a sagittal plane perpendicular to said component transverse plane and including a component midline that is normal to said component transverse plane; the component having a bone-contacting surface and an opposed articulation surface, the component further having proximal, distal, anterior and posterior portions, the component comprising: a pair of condyles including a medial condyle and a lateral condyle, each of said condyles defining respective distal-most points and posterior-most points, said component transverse plane tangent to each of said distal-most points, said coronal plane tangent to at least one of said posterior-most points, and said sagittal plane disposed between said lateral condyle and said medial condyle; and a patellar groove proximate the anterior portion of the component, said component midline of said sagittal plane inclusive of a distal-most point of said patellar groove, said patellar groove extending from said distal-most point toward an anterior-most edge of said femoral component, said patellar groove defining a medially canted patellar axis when viewed from an anterior side of said component, said patellar axis medially diverging from said component midline as said patellar axis extends proximally to define a medially canted angle between said patellar axis and said component midline.
