Abstract: A prosthetic implant useful in a cementless application is disclosed. The implant may include a curved bone facing surface and one or more pegs or keels. Preferably, the implant is implanted on a bone surface that has been prepared so as to allow for a snap fit between the implant and the bone.

Abstract: Disclosed herein are knee replacement systems for replacing the articular surface of a distal femur. The systems include one or more unicompartmental components, namely patellofemoral, lateral condylar and medial condylar components. The components are configured such that when engaged to the femur the peripheries thereof do not cross specific locations and/or regions of the femur, namely the intercondylar notch and condylopatellar notch. The patellofemoral components described herein preferably have an extension portion extending posteriorly from a posterior periphery thereof towards an intercondylar notch or the femur without contacting the intercondylar notch of the femur when the patellofemoral component is engaged to the femur. The extension portion preferably extends posteriorly from a posterior periphery of the patellofemoral component towards the condylopatellar notch of the femur without contacting the notch.
