3B5-3 - Knee prosthetics

Genium X3

Reclaim all you want to be.

The technology of our Genium leg prostheses makes intuitive and natural motion sequences possible, even when walking backwards or climbing stairs, or when switching between different walking speeds and stride lengths. Enhanced safety and quality of life along with relief for the contralateral side are just some of the aspects that can benefit users. And this has been scientifically proven.

Building on the unique functionality of the Genium, the Genium X3 is particularly robust and resilient. Physically demanding occupations, swimming, recreational sports and situations where you encounter water, dust, sand or dirt – these are the ideal conditions for the Genium X3.

The Genium X3 is easy to configure with the Cockpit app 2.0.

Confidence for every step

Thanks to its unique technology, the Genium X3 gives you a smooth gait pattern that is easy on your body, relieving your musculoskeletal system and giving you freedom in everyday life.

Highly natural thanks to industry leading technology

Thanks to intelligent sensor technology, your Genium X3 responds reliably – in real time. As a result, it lets you change walking speeds, take stairs leg-over-leg, overcome obstacles safely, stand in a relaxed position on inclines and walk backwards.

Water? No problem

The Genium X3 lets you shower, swim or work in damp conditions without thinking twice. Special materials, coatings and components protect the electronics. The joint is also waterproof (even when exposed to strong jets of water) and corrosion-resistant against salt and chlorinated water.

Custom modes

Want to permanently configure your knee for activities you do frequently? Thanks to the large selection of MyModes plus, you and your clinician can set up five pre-settings for work, recreation and sports. These can be easily selected using the app or a movement pattern.

Change your prosthesis settings yourself

The new Genium X3 provides the basis for easily configuring your knee thanks to the new Cockpit app for iPhone (iOS) and Android devices. This lets you check the battery charge level or quickly activate your personal pre-settings.

Moving at high speed

Whether you’re running to catch the bus or keeping up with your kids: The walk-to-run function lets you change speeds spontaneously for short sprints. An additional running mode for longer distances was developed especially for sports activities with the Genium X3.

Genium X3 stories - Kerstin


As a mother of two daughters Kerstin is always required. Her Genium X3 proves itself in the home, during sports, when playing with her children, but also in the water.

Genium X3 stories – Réka

Réka lives her life in the fast lane: she studies, blogs as robotgirl_reka and loves being active. She feels especially free whenever she’s running or swimming. Previously fitted with a transfemoral prosthesis and the Genium, her gait was already virtually normal in everyday life and in sports. But now that she wears the Genium X3, she enjoys even greater freedom. 

Genium X3 stories – John

How can you capture an action-packed week in Croatia with two recent graduates testing their limits in challenging landscapes – especially when one is wearing a lower limb prosthesis? Watch the friends excel at every activity – on land and water – one last time and let them do the talking. It is obvious, however, that John feels most comfortable with his Genium X3 – intuitively supporting his each and every move.

Unique technology at the heart of your mobility

Movement is calculated with incomparable accuracy and initiated in real time by the Genium X3, whether on uneven terrain and slopes, when changing speeds or in confined spaces. Studies prove that providing targeted relief for the contralateral side also has long-term health benefits. Particularly robust materials allow even more freedom of movement, including in wet and harsh environments. Patients can benefit from focusing their attention on the important things in life, rather than having to think about every step.

Smart adjustment options via app

It’s all in your hands. Thanks to integrated Bluetooth, the Genium X3 can be configured using an app. This makes it very easy to select additional movement patterns, which are stored by your technician as MyModes. Switch the joint to mute mode when you visit a cinema or theatre. You can also read the battery charge level with the Cockpit app 2.0. The new Genium X3 can be configured with the Cockpit app 2.0 for Android was well as Apple (iOS) devices.

With the market launch of the Genium leg prosthesis, Ottobock opened up entirely new horizons for prosthesis wearers: a nearly natural gait pattern, climbing stairs step-over-step, walking backwards, relaxed standing – to name just a few examples. The benefits of treatment with a Genium have been scientifically proven in multiple studies.

The Genium has been enhanced based on human movement as the model. The result is a noticeably smoother gait and even better support and safety in everyday situations, for instance on ramps, in confined spaces or when changing walking speeds. Five individually selectable MyModes support special movement patterns at work or during recreation. The leg prosthesis can be configured with the Cockpit app.
