A patello-femoral joint prosthesis is provided which allows smooth tracking of the articulating surfaces through a full range of joint motion. A novel configuration of a femoral implant component that facilitates superior adhesion to bone is also provided. Also provided is a patello-femoral joint replacement system, which permits precise, reproducible bone preparation techniques that uniquely permit later revision and full knee joint replacement procedures with minimal complications. Also provided are a drill guide and a cutting guide, each being configured to provide three point stabilization during operation.
