The V One microprocessor four-bar pneumatic knee prosthesis has self adjusting technology combined with a 4-bar polycentric design to create a natural walking style for the user that is smooth, safe and energy efficient.

• Safety and intelligence

A new gravity sensor is integrated to estimate different walking speeds, and the knee prosthesis

resistance can be changed for more natural gait and safety.

• Walking resistances setting

The resistances of the knee joint for three walking conditions (slow, natural, fast walking) are set by the PC program in the auto-mode.

• Four-bar mechanical design

The trajectory of the instance center of rotation (ICR) mimics anatomic pattern, which ensures

stability in the stance phase and toe clearance in the swing phase.

• Carbon frame

It makes knee lighter and more durable
