FASTER THAN YOUR BIOLOGICAL REFLEXES
Three high‑precision sensors trigger real‑time, adaptive adjustments that make each transition feel truly intuitive.
• Angle sensor is 10x more sensitive than traditional MPKs.
• Angle sensor sampling rate is 2x greater than conventional designs
BUILT AROUND YOU
Intelligent engineering that doesn’t limit compatibility or control.
• Personalized Activities: Finely‑tune adjustments and customization for daily routines or specialized activities.
• The most compact MPK: At just 8.5”, pair your knee with a wide range of prosthetic feet, ankles, and blades without compromising alignment or motion.
• Adaptive gait tuning: Adjust your QUATTRO to your unique gait via the patient‑friendly app.
COMFORT IN MOTION
Traditional MPK technology relies on dual‑valve systems that open and close between steps, creating lag that disrupts motion and breaks rhythm.
QUATTRO is powered by a single, bidirectional valve capable of continuous resistance modulation.
It reacts twice as fast and adjusts within milliseconds to stay in sync with user intent. The result is smoother motions that feel more natural and more comfortable.
