Single M/L Radius
The patented,1 clinically successful single M/L radius of the NRG design achieves full conformity at all flexion angles while allowing for increased rotation. The increased conformity of the NRG knee design results in decreased contact stresses during increasing rotation.2
Mechanical testing shows that the Scorpio NRG fixed-bearing design maintains low levels of constraint, up to ±20 degrees of rotation. The NRG knee accommodates rotations of the intact knee on the articulating surfaces for both PS and CR systems. Scorpio NRG PS helps accommodate these rotations on the post where potential wear and damage can occur.
