Abstract
A femoral implant for articulation with a patella or a patellar implant includes a body having an articular surface defining a trochlear groove. The trochlear groove is defined by a first trochlear radius at a first location along the trochlear groove and by a second trochlear radius at a second location along the trochlear groove, the first radius being different than the second radius. The configuration of the trochlear groove is such that it narrows as a patella or patellar implant moves from an extension configuration to a flexion configuration. A kit includes the femoral implant along with a patellar implant. A method of trialing involves use of the femoral implant or kit to ensure a smooth transition of the patella or the patellar implant from the femoral component to the adjacent bone.
