Genium X3 leg prosthesis

Benefits at a glance

Genium X3 underwater


You can shower, go swimming or work in wet conditions with the Genium X3: Select materials such as titanium, hard anodised aluminium, stainless steel and high-end coatings combined with especially sealed components protect the joint's sensitive sensor technology and electronics. The Genium X3 is waterproof and corrosion-resistant. It opens up previously unimaginable possibilities.

Spontaneous response

There are many situations where you need to respond spontaneously: Crossing the street, when a car appears unexpectedly, or when you have children who can always get you into unexpected situations. The Genium X3 responds easily thanks to walk-to-run mode. Switching from walking to running is detected by the electronics within microseconds and the auto-adaptive joint reacts.

Participating in sports

No matter what you demand from yourself in sports, running mode keeps up. It was developed especially for sports activities. Its functions are adapted to running behaviour and based on the natural model. For example, an increased maximum flexion angle of the knee joint required for running is taken into account.

Suitable for everyday use

Walking slow or fast, climbing stairs step-over-step, crossing obstacles with a natural movement, standing safely on slopes or walking backwards: Thanks to the latest computer, sensor and control technology, the Genium X3 responds intelligently to various everyday situations. It even adapts to different shoe weights and clothing.

Genium X3 plus Triton prosthetic foot

A suitable foot

The Triton prosthetic feet are perfect for highly active users. Especially robust, the Triton Heavy Duty has a high load capacity and is resistant to water and corrosion.

Robust Protector

Robust Protector

In order to withstand the many stresses of everyday life, the Protector made of durable PU material covers the knee joint and stands up to even severe strain easily.


The best way to walk is with a natural, physiological gait – whether it be during a relaxed stroll through the city or quickly sprinting to the bus. It is exactly this gait that the Genium X3 replicates almost identically, phase for phase. No matter on what surface, no matter at what speed. With the Genium X3, we have bundled this technology under the term "Optimised Physiological Gait" (OPG). It relieves strain on the entire locomotor system, improves wearer comfort and opens up entirely new freedom of movement for the amputee.

Genium X3 gait cycle

1. PreFlex

The knee joint is already pre-flexed when the heel strikes the ground – the way it is with a natural leg. This is automatically controlled by the electronics. You require less force to initiate a step, since the prosthetic foot makes full-surface contact with the ground more quickly.

2. Adaptive yielding control

Intelligent knee flexion control with full-surface contact between the prosthetic foot and the ground is depending on the forces acting on the prosthesis. You can more safely negotiate hills, uneven terrain and slopes, need to pay less attention to controlling your prosthesis and are able to use it intuitively. Flexion also dampens the impact of the foot, which decreases compensating movements and therefore significantly reduces subsequent orthopaedic problems as well.

3. Dynamic stability control

This is an innovative and patented method to monitor all movement situations. Six different parameters are continuously recorded in order to define the optimum switching point between the stance and swing phase. For you this translates into enhanced safety, among other things when walking backwards or lunging.

4. Adaptive swing phase control

The quality of the swing phase with the Genium X3 is comparable to the natural model. The lower leg pendulum movement is precisely limited to 65° of flexion – regardless of the walking speed. The increased ground clearance minimises the risk of tripping and falling. Even on slopes, the angle-independent swing phase ensures sufficient ground clearance. There is no limitation of step variance, no matter whether you are taking short or long steps, or walking slow, fast or at irregular speed. The system even adapts intelligently to the respective shoe soles and clothing.

Prosthesis training

A prosthesis is only as good as the user's ability to handle it! The Genium X3 is an innovative knee joint that offers you numerous functions. However, these functions have to be learned and practiced, especially in the beginning. This is the only way you can fully utilise the functionality of the Genium X3.

With "Genium Gait Training", Ottobock has developed a training programme that instructs therapists, prosthetists and users in detail about conducting efficient gait training. This gait training can be used for the Genium X3 as well. The programme is illustrated with clear videos. Activities which are practiced include walking backwards, going down stairs and negotiating slopes as well as the Genium X3 standing function, sitting, climbing stairs step-over-step and much more. Numerous exercises have been selected to increase safety and confidence early on in using the Genium X3.

Ideal prosthetic components

Triton: The prosthetic feet from the Triton family of products are suitable for active users. They are made of a set of flexible carbon springs. This design allows the foot to function as a flexible unit, which creates a particularly smooth rollover. Notwithstanding the system's ability to move, the Triton feet provide a consistently high level of stability when walking and especially when standing. Furthermore, the foot's special structure ensures a powerful transition to the swing phase and a highly variable stride length. At the same time, the split forefoot section gives the user the necessary control to deal with uneven ground and quick changes of direction. The Triton is extremely well suited for meeting the requirements of an active lifestyle. Thanks to its outstanding dynamic response and flexibility, it supports a broad range of applications from everyday use to recreational sports.

Triton Low Profile: The Triton Low Profile makes the excellent functionality of the Triton available even to users with limited space for the integration of a prosthetic foot.

Triton Heavy Duty: The Triton Heavy Duty is especially strong and robust. It features an adapter made of titanium. Non-corrosive metal parts make the foot water-resistant as well.

Genium X3


  • Who can wear the Genium X3?

    The Genium X3 is suitable for all transfemoral amputees who benefit from the outstanding everyday characteristics of the Genium and want to discover new horizons thanks to the water and corrosion resistance of the Genium X3.

  • Who provides fittings with the Genium X3?

    The Genium X3 is adapted exclusively by certified prosthetic service provider that have participated in special training and have experience with Genium fittings.

  • Can I just try out the Genium X3?

    Yes, many certified prosthetic service provider offer a trial fitting. As a rule, your prosthetic service provider will recommend testing the outstanding functions of the Genium in a first step, and then trying out the expanded application possibilities of the Genium X3 in a second step. The trial fitting takes place over a predetermined period of time (usually a week) and is monitored by Ottobock when needed.

  • How long does it take to learn how to use the Genium X3?

    It depends. Many users can climb stairs step-over-step on the first day with the Genium X3. However, this can also take several days or weeks; it varies between individuals since everyone is different.

  • What else is included in a prosthetic fitting with the Genium X3?

    A fitting with the Genium X3 includes all components from a suitable foot to the knee joint system, including the socket, which will be customised to your individual needs by your prosthetic service provider. Of course the assembly and setup of the system are also included, as well as regular service inspections.

  • How long will the battery of the Genium X3 last?

    Intelligent energy management integrated in the Genium X3 results in a battery capacity of up to 5 days when fully charged. However, we recommend charging the knee joint daily overnight.

  • What happens when the battery is drained?

    Vibration messages provide a timely warning when the battery charge gets too low. Once the battery is drained entirely or the power supply fails, the Genium X3 automatically switches to safety mode.

  • Can I shower or go swimming with the Genium X3?

    The Genium X3 is resistant to water and corrosion, so that it can be worn while showering and swimming without any problems. However, the Genium X3 should be rinsed with fresh water afterwards. It is not designed for actual diving.
