Abstract

A system for use in a total knee arthroplasty procedure can include a first cutting guide, an alignment guide and a femoral prosthetic implant. The first cutting guide can include at least one planar guide surface adapted to guide a cutting tool to cut femur. The alignment guide can contact the femur and provide for markings to be made in the femur that dictate a location and orientation of the first cutting guide. The implant is adapted to be implanted on the resected femur. The implant can have an inwardly protruding structure to provide medial-lateral fixation stability, and can have an anterior fixation path that diverges proximally away from a long axis of the femur and a posterior fixation path that converges proximally towards the long axis such that the posterior fixation path and anterior fixation path converge toward one another proximally of a distal contact surface.
