The NEURO VARIO 2 system knee joint is a free moving, monocentric joint. Through an integrated posterior offset, it provides a secure stance. It has a static, adjustable extension stop. The range of motion in extension can be infinitely adjusted from 0° to 20° by using the alignment screw. The bumping noises are minimised thanks to the extension stop damper.

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 angle can be adjusted optimally to the correct tibia inclination.
