Scorpio NRG Knee System
Unlike other modern knee replacement designs, the Scorpio NRG Knee has greater internal and external rotational freedom throughout the full range of motion.1 Mechanical testing illustrates that the Scorpio NRG fixed bearing design has comparable rotational allowance to competitive mobile bearing knee systems, without sacrificing contact.1 The core technology of the NRG knee carries forward several clinically tested concepts from the Scorpio Total Knee System.
The Scorpio NRG tibial insert’s articulating surface adapts a Spherical Arc to realize greater rotational freedom. By meshing a single M/L radius and a Spherical Arc, NRG allows for wider rotational freedom without restricting tibio-femoral contact area.
