Genium X3 Technology

The world's most technologically advanced prosthetic leg


Above-knee prosthesis with GENIUM X3

The result of a collaboration between the US military and Ottobock, the X3 is quite simply the world’s most technologically advanced microprocessor prosthetic leg.


You may have a challenging or adventurous lifestyle. Or, you may simply want to keep up with everyday activities (showering, hiking, running to catch a bus) without having to worry if your prosthesis can make it through.

Advantages of GENIUM 3


The most natural gait possible

An accelerometer and a gyroscope intuitively know where your leg is in space, using the same technologies from Wii™ gaming systems and smartphones, for a virtually natural gait. That means less worry of a stumble or fall and less concentration needed when you’re on the move.

REAL-WORLD MOBILITY Real-world mobility

More physical capabilities 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 movement. You’re always in control.


The X3 has undergone stringent waterproof testing. Completely submersible, the X3 allows unprecedented contact with water. Perfect for anyone working near water or for activities such as showering, washing your car, or boating. (Just be sure to clean it afterwards.)


We’ve added a simple “Assurance” cover (right) as a contrast to the original “Xtreme” cover (left). Ask your practitioner which is best for you. With either choice, you get the ultimate in rugged, waterproof performance. Both covers can be purchased separately, as an accessory.

RUNNING ON THE GENIUM X3 LEG Running on the Genium X3 Leg

Via the remote, the X3 switches into a larger swing angle for running and other sports. Plus, the innovative Walk2Run mode detects start-and-stop running (such as crossing a street or trying to catch a bus) and automatically increases your swing angle.

ROBUST AND READY Robust and ready

The X3 is “ruggedized” based on conditions an active duty military member might face. That means it’s up to any challenging terrain you may encounter!

KEEP GOING FOR LONGER 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, giving you greater independence.

EVERY STEP IS SMOOTH AND SECURE Every step is smooth and secure

Choose any of the Triton feet from Ottobock to complete your X3 system — these two are waterproof:

  • the Triton Heavy Duty, robust and waterproof, for particularly challenging conditions), or

  • the Triton Low Profile, with especially low structural height for those who need the extra room

5 Activity Modes

Five activity modes allow your choice of activities – biking, golfing, driving, and more – activated using a key fob-sized remote. Just strap on the remote control via its Velcro wristband – you’re ready to go!
