Abstract
The present invention relates to a femoral prosthesis that includes a cement introduction port which may be used to facilitate delivery or introduction of bone cement into the prosthesis/bone interface after the prosthesis component has been placed on a resurfaced femur bone. The femoral prosthesis may have a keel with undercuts which are configured to assist in controlling the flow of bone cement during implantation and to improve stability of the prosthesis following implantation. The femoral prosthesis is suitable for implantation using arthroscopic, as well as open, surgical procedures. The present prostheses may be used as unicondylar implants in either compartment of the knee or in both compartments of the knee.
