Product range: 10 femoral sizes;
10 tibial sizes; 10 insert thicknesses*

GKS PRIME FLEX PS MOBILE is the mobile bearing posterior-stabilized option of the system.
The femoral component PS is available in the cemented version only and the tibial component is the same tibia of the Mobile version.

Femoral component

The femoral component was designed for minimal bone sacrifice thanks to the limited thickness and reduced size increments (2mm) as well as the reduced bulk of the intercondylar box (open bottom) and the absence of the femoral pegs.
It is available in 10 sizes in MICROLOY® version and with BIOLOY® surface coating, both for cemented application.
Particular attention has been given to the posterior stabilization mechanism, in order to reduce the stresses and guarantee a gradual roll-back with a “soft” contact between post and cam.

Articular insert PS Mobile

The articular insert PS Mobile has a “post” that articulating with the cam of the femoral component performs the function of the PCL and due to the ultracongruent design provides high stability, offering in the meantime an optimal ROM.
It is composed of UHMWPE, also available in VITAL-E® version with anti-oxidizing Vitamin E.

* Some thicknesses may be on request.

Socket for patellar tendon sliding

Tibial component

The design of the tibial component provides a flanged keel for metaphyseal anchorage which opposes the anterior-posterior tilting movements and torsion forces.

The tibial component is available in 10 sizes, both in cemented and cementless version with HaX-Pore® coating.
