Above-knee prosthesis with: Genium

Reclaim your strength

Walk naturally

The Genium microprocessor prosthetic leg is quite simply the closest technology has come to natural walking. Imagine work, family, or leisure time activities without having to think about your next step. If your active life demands more function, this is the system you need.

Go to the Advantages for You tab below to learn how the Genium can transform the way you walk.

Intelligent AXON tube adapter

The AXON tube adapter measures in real time both the ankle moment and also the vertical force acting on the joint. The AXON tube adapter can be connected with a foot without an intermediate piece.

Knee moment sensor

The knee moment sensor supplies data about the knee moment and therefore provides important information for precisely determining the forces acting on the prosthesis.

Hydraulic unit

The hydraulic unit controls the Genium. By means of two control valves, the resistances of flexion and extension of the joint are controlled independently

Carbon fibre frame

In order to withstand the varied demands of everyday life, the frame is made from carbon - an especially strong, high-grade and lightweight material.


Integrated Bluetooth technology permits simple communication with the joint. If necessary, the function can be disabled.

Inertial Motion Unit (IMU)

Gyroscope and acceleration sensors allow the determination of position and speed of the Genium in space in real time. An angle sensor determines the flexion angle and flexion angle speed. The prosthesis control is based on an analysis of the movements and the force acting on the joint.

Inductive charging

The inductive battery charger is connected with magnets to the back of the knee joint. This technology allows charging through clothing and cosmetic covers.

Battery and electronics

In the Genium, the battery and electronics are enclosed and protected by the frame. The integrated microprocessor coordinates all measurement and control processes.

What you need to know

Advantages for you

Walk up stairs step over step

The ONLY microprocessor knee that lets you walk upstairs under your own power, thanks to Genium’s many sensory inputs.

Cross obstacles more smoothly

Now everyday obstacles can be stepped right over—supported by a stable, flexed knee when your foot strikes the ground. No more awkward swinging your prosthetic leg around the impediments of daily life.

Walk backwards, forwards ... and more

Genium detects your forward and backward motion and provides support as needed. You’ll be secure even when stepping backwards or changing direction

Stand more easily

The Genium can tell when you’re standing and automatically resists further flexing. Suddenly, you’re more relaxed while standing, saving you energy and taking stress away from your sound side – even on inclines and uneven surfaces.

Sit more naturally

If you sit for more than 2 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 Genium. But even better, the Genium is rated – which means you are protected against splashed water from all sides.

Every step is smooth and secure

Choose Ottobock Triton feet from Ottobock to complete your Genium system:

Lightweight and responsive, chose from

• Triton smart ankle with adjustable heel height

• Triton Vertical Shock for compact comfort

• Triton Harmony with integrated vacuum, or

• Triton Low Profile for extra room.

Cockpit App for Android puts control at your fingertips

Just like the remote control, you can now check battery life, watch step counts, and switch between 5 modes. The app adds adjustment options, too!

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

With a battery life of 5 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 a snap — 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: Prepares the knee for flexion in loading with every step by maintaining a controlled 4o of knee flexion at initial contact

  • Improves shock absorption and a more equal stride
  • Makes slopes and uneven terrain easier to handle and reduces compensatory motions
  • Helps make swing initiation easier.

(2) Adaptive Yielding Control: Stance flexion and stance extension resistances optimize movement.

  • Intuitive yielding for stance flexion and stance extension
  • Improves efficient control of prosthesis
  • Provides more stability in stance flexion
  • Prevents extension “snap-back” of knee at mid-stance.

(3) Dynamic Stabiility Control (DSC): The main electronics monitors six sensor inputs to ensure appropriate timing for stance release.

  • Makes it easier to take quick steps in any direction – forwards, backwards, and sideways
  • Increases stability when walking backwards.

(4) Adaptive Swing Phase Control: Swing phase flexion and extension resistances change in real time.

  • OPG function is not limited by walking style or pace: quick, slow, irregular
  • Eases completion of swing phase, reducing the risk of stumbles and falls
