The femoral component, made of chrome cobalt alloy with BIOLOY® coating, is available in 6 anatomical sizes that can be used on both condyles (right medial to left lateral and vice versa) in cemented and cementless versions (R3 BIOLOY® version with HaX-Pore® coating only) and 3 different options:
- R3 (distal thickness 3mm) and R5 (distal thickness 5mm) are ‘resurfacing’ type and have an internal profile that reproduces the curvature of the femoral condyle, allowing straight resections to be limited to the posterior condyle only, thus preserving bone stock.
- CH, on the other hand, has an internal profile with angular resections (distal and posterior bevel).
The sagittal curvature of the femoral component has three load arcs with distinct centers, with varying radius depending on the size.
The stability of the femoral component is guaranteed by two cylindrical pegs that align with the mechanical axis of the femur, as well as by a longitudinal flange (not present in the CH version).
