Functional Advantages
Enhanced Stability
The polycentric four-bar geometry positions the instantaneous center of rotation higher and posterior during stance phase, improving knee stability during heel strike and weight acceptance.
Smooth Swing Dynamics
Integrated pneumatic swing control provides controlled knee flexion and extension for smoother gait transition and improved cadence adaptation.
Better Ground Clearance
The shortening effect created by the polycentric linkage improves toe clearance during swing phase, reducing the risk of stumbling.
Lightweight & Durable
Manufactured using precision CNC machining and high-strength materials for long-term durability and optimized weight balance.
