X3 microprocessor knee

The X3 is the most durable, intuitive and technologically advanced microprocessor knee on the market. Developed in collaboration with the US military, it is the first fully waterproof and corrosion resistant knee available. 

Waterproof
The X3 has undergone stringent waterproof testing. Completely submersible, the X3 allows unprecedented contact with water including showering, swimming, boating, fishing and now with the latest version, protection against water jets. Ideal for patients working in or near water!

Run, walk, run
Via the remote or new Cockpit app for Android, the X3 can switch into a larger swing phase angle suited for running and other sports. In addition, the innovative Walk2Run mode is ideal for running short distances and start-and-stop running such as across a street, down the hall or to catch a bus. In that mode, the X3 detects a walk-to-run transition and the swing angle automatically increases, with no preflexion.

Robust and ready
The rugged design of X3 is based on conditions an active duty service member might face. As a result, X3 can withstand the elements – from rough and tough terrain to diving into water.

The most natural gait possible
The X3 features Inertial Motion Unit control, a patented technology from Ottobock that enables the prosthesis to identify where a user’s leg is in space. This feature, coupled with unique Optimized Physiological Gait 2.0 technology, enables the user to walk with the most natural gait possible, step backwards with confidence, tackle stairs, slopes and uneven terrain and worry less about stumbling or falling.

Real-world mobility
More physical capabilities for the real world than any other prosthetic leg including running, walking backwards, crossing obstacles in a more anatomically correct way, and climbing stairs step-over-step without massive compensating movements – ­an action that previously appeared impossible for those with above knee limb loss.

Keep going for longer
X3 offers improved battery life and an automatic "sleep" mode. That translates into five plus days of use without the need for a recharge and results in greater independence.

5 activity modes
Programmed using a laptop and integrated Bluetooth technology, five activity modes can be set for biking, golfing, driving and more. They are activated using the Cockpit app for Android or iPhone.
