1. An integrated prosthetic assembly for implanting a prosthetic knee joint between a femur and a tibia to include at least one graft that extends through a femoral tunnel, or a tibial tunnel, or both, the assembly comprising:
- a plurality of femoral components each including a femoral clearance;
a plurality of tibial components each including a tibial clearance defining a tibial passage; and
at least one drill guide adapted to guide an instrument during the implantation procedure to precisely place a tunnel in the femur or the tibia to be aligned with either of the femoral clearance or the tibial clearance;
wherein each of the plurality of femoral components, plurality of tibial components, or both provide a different final geometry to the knee joint prosthetic when implanted, wherein each of the plurality of the femoral components includes a first of the femoral clearances adapted to allow the anterior cruciate ligament to clear the femoral component and a second of the femoral clearances adapted to allow the posterior cruciate ligament to clear the femoral component, and wherein each of the first femoral clearances operably interact with the anterior cruciate ligament to produce rollback at a predetermined flexion of the knee joint.
