3B1-3 - Knee prosthetics


Choose intuitive flow
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 being fitted 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 play.The Genium can be configured with the Cockpit app, which is now available not only for Android but Apple (iOS) devices as well.

Benefits at a glance

Intuitive flow with every step

Free your mind
Natural gait pattern with OPG

Thanks to its unique OPG (Optimized Physiological Gait) technology, the Genium supports an exceptionally smooth walking pattern. This gait is easier on the user’s body, providing more freedom and flexibility for everyday moments and activities.

An excellent long-term fitting
Support for everyday obstacles

Life is full of ups, downs, and everyday challenges. With the Genium, users can easily take stairs step-over-step and overcome obstacles such as curbs.

Weatherproof design (IP67)

Now users don't have to worry about encountering occasional water splashes. Whether they walk past a sprinkler, work in the garden, or get caught in an unexpected rain shower, their Genium is designed to stay protected and fully functional.

Relaxed standing
Relaxed standing

The Genium features two different stance functions that allow users to rest on their prosthesis. The result is continual relief for the sound side. Bilateral users benefit from this function as well.

MyMode plus
MyMode Plus

Genium users can easily get more support for their favorite activities. MyModes offer a fantastic selection of options for work, leisure, and athletics. Together with their prosthetist, users can select five modes for easy activation via the Cockpit app.

Simple control on the go: the Cockpit app
Smart control via app

With the Cockpit app, users can fine tune settings individually, switch between MyModes, check their battery life, set their volume, track their activities, restart their knee joint if needed, and more — all via their iOS or Android smartphone. 

User Experience

Genium users jump into life with both feet

Aaron’s Genium story

Aaron loves being a father. Above all else, it’s important for him to be able to keep up with his fast-paced family. A bilateral amputee, he takes on every challenge possible – be it at work or in his free time. When fishing, Aaron can relax, be all by himself and get lost in his thoughts.

Hamed’s Genium story

Hamed leads an active life filled with family, friends and sports. He is always seeking new challenges and setting goals for the future. This attitude towards life also helped him a lot during the difficult time he experienced after the amputation when he was a child. His leg prosthesis accompanies and supports him in his varied activities in everyday life. 


Advanced technology, exceptional control

Unique technology at the heart of your mobility

The Genium’s introduction in 2011 represented a breakthrough in knee joint technology – but it didnt’ stop there. Every step of the Genium’s development has pushed the limits of technology further with the goal of coming even closer to the natural model. Years of research and development work have resulted in the Genium as we know it today. Movements are calculated with incomparable accuracy and triggered in real time. The technology recognises whether the patient is on uneven terrain or inclines and whether they are changing speeds.

Studies have proven the long-term health benefits of the targeted relief it provides for the sound side. Compensating movements are reduced. Thanks to the Genium’s intuitive use, patients benefit from being able to focus their attention on the important things in life, rather than having to think about every step.

Smart app control

Thanks to integrated Bluetooth®, the Genium can also be controlled with an app. Additional movement patterns are stored as MyModes and can be very easily selected using the corresponding app. Mute mode can be selected via the app as well and is ideal when visiting the cinema or theatre, for example. The battery charge level can also be checked in no time using the Cockpit app, which is available for the new Genium on both Android and Apple (iOS) devices.

The sensor technology in the Genium X3 makes intuitive and natural motion sequences possible, even when you’re 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 patients considerably; and this has been scientifically proven. The Genium X3 is particularly robust and resilient. Physically demanding occupations, an active family life, swimming and sports activities, seaside holidays and situations where you encounter water, dust, sand, dirt or grime – these are the ideal conditions for the Genium X3. The Genium X3 has now been developed even further on this basis for smoother, more intuitive walking, improved safety and better support in everyday situations. The Genium X3 is incredibly simple to configure using the Cockpit app on your iPhone or Android smartphone.
