Polycentric Pneumatic Knee Joint
The Polycentric Pneumatic Knee Joint is for users approaching walking who need pneumatic flexion and swing softness. Extension and flexion are completely assisted and can be customized for each patient through two pneumatic valves.
- Pneumatic flexion and swing softness
- Extension and flexion fully assisted and customizable per patient through 2 pneumatic valves
- Variable CIR polycentric mechanism; at initial contact the knee is locked in full extension
- Studied geometry allows prosthetic shortening during push off to avoid stumbling
- Flexion angle 150 degrees
- Aluminum alloy 7075, component weight 750 g
- Maximum user weight 130 kg
- Tested to ISO 10328
- Warranty 36 months
- Pair with RoadflexionHP to build a key level 3 above knee prosthesis
Very high CIR and close to the hip, low fatigue to start flexion.
Posterior CIR to the load line.
Very closed CIR to the load line, good for voluntary control.
POLYCENTRIC KNEE JOINT SYSTEM
Thanks to the pyramidal adapter suitable for each knee, it’s possible to change the CIR position compared to the LOAD LINE in order to offer users more safety or more voluntary control.
Community ambulation.
Variable cadence gait (or potential).
Most environmental barriers.
