A knee prosthesis for press fit implantation without fixation cement, including a femoral component (10) in which the dual bearing members (12, 14) each have a distal fixation surface (22, 28) which is curvilinear and concave when viewed in sagittal planes. A novel cutting jig (48) and saw blade (98) for preparing the distal femur for implantation of the femoral component are also disclosed. The fixation post (32, 44) of both the femoral and tibia components of the prosthesis is vane shaped in cross section, and the textured fixation surfaces of the components may include a layer (46) of biocompatible felt material for distributing stresses between the component and the prepared bone member.
