Until now, the NEURO VARIO 2 and NEURO VARIO-SWING were only available in the system width 20mm. We are now extending our product range, which is why you can now also purchase the two free moving system knee joints in the system widths 12, 14 and 16mm. This allows you to supply children or shorter and more lightweight patients with system knee joints with plug + go modularity as well.
The system widths 12 and 14mm are available in a straight shape, the system widths 16 and 20mm in both a straight and bent shape. You can find more information about the system knee joints on the catalogue pages NEURO VARIO 2 and NEURO VARIO-SWING.

As a refresher, here is an overview of the special features of the two system knee joints:

Flexion Adjustment
The system knee joints NEURO VARIO 2 and NEURO VARIO-SWING have an infinitely adjustable extension stop. The range of motion in extension can be limited from 0° to 20° by using the alignment screw.
 | NEURO VARIO 2 and NEURO VARIO-SWING belong to the free moving system knee joints. Due to an integrated posterior offset, they provide a secure stance. With both system knee joints, the bumping noises are minimised using extension stop dampers. |
 | The NEURO VARIO 2 system knee joint is ideally combined with a system ankle joint with an infinitely adjustable dorsiflexion stop, such as the NEURO VARIO 2 system ankle joint. Thus, the knee flexion can be adjusted optimally to the correct tibia inclination. |
 | The NEURO VARIO-SWING system knee joint is ideally combined with a system ankle joint with an infinitely adjustable dynamic dorsiflexion stop, such as the NEURO SWING system ankle joint. Thus, the knee flexion can be adjusted optimally to the correct tibia inclination. |
Dynamic Extension Stop with NEURO VARIO-SWING
The dynamic extension stop enables an extending movement against resistance which exceeds the set extension angle (e.g. from 5° downwards to 0°).
The resistance in extension can be modified by using interchangeable spring units. Five spring units with different resistances and colour markings are available.
A spring unit with a green colour marking is premounted in the system joint. The spring unit has a maximum range of motion of 9°. Such a range of motion usually supports a harmonious and physiological gait pattern best.
Depending on the selected spring unit, the maximum range of motion of the spring’s range is between 3° and 9°. The range of motion of the spring’s range of the dynamic extension stop can be infinitely limited to 0° by using the motion limiting screw.
Stance
Not only when walking, but also during stance, this extension stop provides dynamic for the patient. This allows the patient to push the knee into a slight hyperextension against the resistance of the spring unit while standing. This additional range of motion guarantees the highest possible wearing comfort and stability.
Walking
When walking, the dynamic extension stop enables a complete knee extension, which is physiological for many patients between mid stance and terminal stance.
The transmission of the stop impacts to the patient leg is dampened by the dynamic extension stop.

More Flexibility for System Knee Joints
System knee joints with plug + go modularity can be converted into another system knee joint with plug + go modularity by exchanging the functional unit.
All functional differences derive from the cover plate, which can be exchanged quickly and easily to convert between the system knee joints.

Large selection of Joint Versions for an Individual Fit
Use the Orthosis Configurator to independently assemble the system components for a KAFO with NEURO VARIO 2 or NEURO VARIO-SWING system knee joint as an ideal supplement to a system ankle joint with infinitely adjustable static or dynamic dorsalflexion stop.
The Orthosis Configurator determines the appropriate system components using patient data and taking the load capacity into account.
