Abstract
A femoral implant includes a medial compartment, a lateral compartment and a trochlear groove in between the medial compartment and the lateral compartment. A central axis bifurcates the femoral implant and extends in a transverse plane perpendicular to a posterior condylar axis, the posterior condylar axis passing through a posterior-most point of the medial compartment and a posterior-most point of the lateral compartment. The trochlear groove is aligned on a trochlear groove axis that extends from the posterior condylar axis at a lateral angle relative to the central axis, the trochlear groove axis being in the transverse plane.
