Total condylar prosthesis placement in knee arthroplasty. Biomechanic analysis of human knee preparations

Knee replacement using the Total Condylar Prosthesis was carried out on six large cadaveric knees. Tibiofemoral articulation was studied radiographically with the tibial component placed anteriorly as well as posteriorly on the tibial plateau. It is concluded that, in this model, when using the Total Condylar Prosthesis for big-sized knees, a tall, posteriorly placed tibial component gave the best placement of the femoral component and the most central tibio-femoral articulation, entailing optimal distribution of the load on the trabecular bone beneath the tibial component.
