More intuitive for elevated security and dependability

The sophisticated technology of QUATTRO is designed to deliver safety and security. With three hyper-responsive sensors and a patented valve made to read and react to your body’s biomechanics, you can trust your knee every step of the way.

QUATTRO Control Technology’s patented valve allows infinite levels of resistance to accommodate each person’s unique movements, making transitions between activities effortless.

Three hyper-responsive sensors read body movements to react to the natural gait of each patient.
