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 central femoral recess between the condyles providing access to the femur for drilling a channel through which a cruciate ligament substitute may be integrated into the femur. The tibial component further includes a center portion defining an aperture through which the ligament substitute maybe threaded through the tibia and integrated therein, or anchored upon its surface. 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.
