GSK PRIME FLEX Fixed Bearing knee prosthesis

GSK PRIME FLEX Fixed Bearing knee prosthesis

Category: Permedica Orthopedics

INTENDED PURPOSE:

GKS PRIME FLEX is a three-compartimental knee prosthesis to be used in Total Knee Replacement procedures. Indicated for primary Total Knee Arthroplasties in cases of advanced osteo-cartilagineous degeneration of the knee joint mainly due to arthrosis, rheumatoid arthritis, posttraumatic factors, and outcomes of corrective osteotomies.Anchorage of the device to the bone may be cementless or cemented, depending upon the selected version.


MATERIALS:

            FEMORAL COMPONENT: Cobalt Chromium Molybdenum alloy - ISO5832/4;

            TIBIA: Titanium Aluminium Vanadium alloy - ISO5832/3;

            ARTICULAR LINER / PATELLA: UHMW PolyEthylene without Calcium Stearate - ISO5834/1/2;

            Also available in VITAL-E® option, added with Vitamin E.


STERILIZATION:

            Method: Ethylene Oxyde (EtO) or irradiation (Beta/Gamma rays - minimum dose 25 kGy) or Vaporized Hydrogen Peroxide (VH2O2).

            Validity: 5 years (Beta sterilized products) - 10 years (EtO/Gamma/VH2O2 sterilized products).


FEMORAL COMPONENT


10 Femoral sizes


The femoral component is common for both the mobile and fix bearing options of the GKS PRIME FLEX range and it’s design was studied to optimize prosthesis performance during flexion: the posterior condyle thickness and curvature range allows ample contact area even at elevated flexion.

Manufactured in Cobalt-Chrome alloy, available in both cemented and cementless version and also with the BIOLOY® ultrahard finishing surface.



HeXPore


The double HaX-Pore® bio-active coating on the bone contact surface of the cementless components promotes osseointagration favouring biological fixation.








2Versions   9Thicknesses


Manufactured with Ultra high molecular weight polyethylene is also available in VITAL-E® version. The CR option is designed to ensure optimal behaviour when the PCL functions are preserved.

The AS (Anterior Stabilized) option is anatomically shaped with a high medial anterior lip that avoids posterior slipping of the tibia when the PCL functions are compromised.

Colour coding for correct coupling between Tibial component and Insert.





 



10 Tibial sizes



The TOP Tibial component is manufactured in Titanium alloy, available in cemented and cementless HaX-Pore® coated option. It is characterized by a symmetric baseplate providing a conical central core with flanged keel for metaphyseal anchorage which opposes the anterior-posterior tilting movement and torque forces.


The distal end can be equipped with a conical Extension Stem.

It is available in 10 sizes divided in 5 couples, each one accepting one size of joint liner and compatible with the GKS PRIME FLEX PS System.
