Abstract
The present invention relates to an implantable knee joint prosthesis which is designed to replace the engaging surfaces of the femur and tibia of a dysfunctional human knee joint. In its most general form, the invention comprises an implantable knee joint prosthesis having a tibial stem portion, a tibial tray portion, an interchangeable modular articulating surface member which is removably attached to the tibial tray portion, and a femoral portion adapted to cooperatively bear upon the articulating surface. The invention also features a dual locking mechanism which attaches the articulating surface to the tibial tray portion by means of a locking lip and flange arrangement together with a locking screw which fits into the tibial stem portion.
