ABSTRACT:
A prosthetic knee implant for implantation into a mammal, which accommodates an anterior cruciate ligament substitute to provide stability to the knee implant. The prosthetic knee implant includes a femoral component having a pair of condylar surfaces and a tibial component having a surface portion adapted to slidably engage the femoral component upon rotation of the same. The femoral component further includes a recess between the condyles defining an aperture through the femoral component. The tibial component further includes a center portion defining an aperture through the tibial component substantially at its center. The femoral aperture and the tibial aperture are adapted to receive an anterior cruciate ligament substitute for biasing the mammalian femur and tibia together. Also disclosed is a method used to replace the total knee joint in a mammal with the improved prosthetic knee implant of the present invention.
