Femoral Component - Sphere shaped articular surface for reducing contact stress and improving stability - Anteriorflange shape and dimension forthe optimal patella tracking - Single axis concept for articular stability with flexion and improving ROM - Extended posterior condylar design for more than 140 degree deep flexion Tibial Base Plate - Stem with keel for improving initial implant stability - Posterior slope for improving rotational stability - 3 size keel design based on anatomy - Commonality of tibial base plate: CR/PS in fixed type, PCS/PS in mobile type - Ground finish of fixed tibial insert mating plane for decreasing back side wear Tibial Insert (Fixed) - High conformity at the frontal plane to maximize contact area - Double radius (anterior high, posterior low) at the sagittal plane for anterior stability and deep flexion - Rotated articular surface considering axial rotation of the femoral component - Improved anterior relief for deep flexion - Rounded tibial post to reduce edge loading in the PS type Tibial Insert (Mobile) - Wear reduction on the surface of the tibial insert by increasing contact area of the femoral component and the tibial insert - Improved stability of the A-P articulation due to deep dish design - Better kinematic performance and joint stability due to the "only rotation" concept All PE Component - Improved joint performance and stability due to introduction of the same features as modular tibial insert - Enhanced resistance of deformation and wear by maintaing the PE thickness for at least more than 10mm - Application of design features to improve fixation with bone cement
