The Genium - Microprocessor Knee

A new world of movement for you

Advantages for you

Stairs and obstacles function

The stairs and obstacles function is unique in the field of prosthetics. It allows users to negotiate stairs step-over-step with virtually no compensation and intuitively whilst moving, with no special commands - an innovation that was unthinkable for non-motorised prostheses. Whether curbs or obstacles in the household - things of that nature, you can quite naturally overcome with the Genium.

Run, walk, run - Running on the new Genium prosthetic leg

Via the cockpit app, the new Genium 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.

Mute Mode

Sometimes feedback by sound or vibration of the joint is not desired - for example, in the cinema, theatre, at work, around the middle of a lecture, or at home when children are asleep. With the new Genium, it is possible to activate the Mute mode via the Cockpit app or the remote control. Then, only emergency messages are sent by the joint.

The advantage for bilateral prosthesis users

In the development of the Genium, we have paid particular attention to the needs of bilateral transfemoral amputees. Together with bilateral Genium users, we have developed solutions that meet the desire for more stability and safety. An example is the conscious standing function. Here, you initiate the function for a natural standing deliberately and finish also with a distinct signal, and that by relieving the prosthesis or slightly straightening it.

Sit more naturally

If you sit for more than two seconds (with your thigh parallel to the ground and minimal weight on the leg) the Genium reduces resistance to take a more natural position—and switches to an energy‑saving mode!

Water-resistant—and more!

Everyday dust and dirt is no problem for the new Genium and even better it is now rated to IPX-54 – which means it is weather proof and you are protected against splashed water from all sides. The new Genium is tested to IPX Standards.

Every step is smooth and secure

Choose one of the Triton feet from Ottobock to complete your Genium system:

  • the lightweight Triton carbon fibre foot with exceptionally smooth control.
  • the Triton Vertical Shock (VS) with great shock absorption in a compact design.
  • the Triton Harmony with integrated vacuum technology;.
  • 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

Simple control when being mobile: the Cockpit app

With the new Cockpit app for Android devices, the Genium provides an easy way to control the joint and to enable & disable functions such as the sitting function. The app also displays additional information such as the charge level of the Genium battery. A remote control is of course available as an optional accessory.

No need to interrupt your busy day to re-charge.

With a battery life of five days, there’s no problem if you need extra time away from your charger. Plus, Genium’s charger is connected with magnets to the back of the knee. Makes charging easy - even through clothing or cosmetic covers – and no open charging ports.

How the Genium works

Genium’s advantage: Optimized Physiological Gait (OPG)

How does it work?

(1) Preflex

The Genium maintains a hydraulically controlled 4˚ of preflexion of the knee joint when your heel starts your stride (heel strike), which allows your foot to reach full contact more quickly and gives you a more stable start to your step.

(2) Adaptive Yielding Control

Intelligent knee flexion (max. 17˚, depending on the situation) gives you more efficient, intuitive control of your prosthesis.

  • Because the knee is flexed it better absorbs shocks and helps limit future orthopedic problems.
  • Easy to take off with a quick step or side step.
  • Makes slopes and uneven terrain easier to handle, while reducing the need for you to make compensating movements.

(3) Dynamic Stability Control (DSC)

The heart of the system: DSC continuously samples multiple environmental inputs—including a gyroscope and 2-axis accelerometer—which determine the appropriate resistance (support) and release at any time during your walking cycle. That means optimum security for you.

  • Supports multi‑directional movement, so you can take quick steps— forwards, backwards, and sideways.
  • Increases stability when walking backwards.

(4) Adaptive Swing Phase Control

You get precise control of your lower leg no matter what your walking speed is. This also helps to prevent falls.

  • The quality of your swing phase (when your leg is off the ground) is far superior to other prosthetic knee joints.
  • It’s easier to swing your knee through during a stride, helping reduce the risk of stumbles and falls.
  • There are no limits on walking style: quick, slow, irregular— Genium handles it all.
