Genium microprocessor-controlled knee joint

A milestone in artificial limb technology

The Genium provides an intuitive, natural gait

The microprocessor-controlled Genium supports the natural movement pattern down to the details – without requiring the user to consciously control the joint. Everything happens in real time, regardless of the situation, and even forward-looking. This is made possible by the latest computer, sensor and control technology. The Genium responds intelligently to a wide variety of everyday situations. This is the closest an above knee artificial limb system has come to recreating a natural, physiological gait pattern.

Inductive charging

The inductive charger is magnetically attached to the back of the knee joint. It makes charging straightforward, even through clothing or the cosmetic cover.

Hydraulic cylinder

The hydraulic cylinder controls the Genium. It generates movement resistance for the stance and swing phases.

Carbon fibre frame

In order to withstand the variety of day-to-day stresses, the frame is made of carbon – an especially high-grade and lightweight material.

Gyroscope, acceleration sensor and angle sensor

The gyroscope and the acceleration sensor allow the acceleration and position of the Genium in space to be measured. An angle sensor determines the flexion angle and flexion angle speed of the joint.

AXON tube adapter

Sensors in the tube adapter measure the ankle moment and the vertical force acting on the joint. The sensor data help make a natural movement pattern possible.

Knee moment sensor

The knee moment sensor provides important information for precisely determining the forces acting on the prosthesis.

Battery and electronics

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



The benefits at a glance

Climbing stairs step over step

With the Genium's stair function, you can climb stairs step-over-step. With a flowing movement pattern, whether you are going up or down.

Overcoming obstacles

Curbs, obstacles or other everyday tripping hazards can be handled with natural movements and improved safely.

Standing, even on slopes

The Genium recognises when movement is required and when load bearing at rest is needed – even on slopes or uneven surfaces. You stand naturally and safely.

Walking backwards

The OPG function (optimised physiological gait) offers increased safety for walking backwards or suddenly lunging.

Optimised swing phase

Short, long, slow, fast or irregular steps – the Genium even adapts to different weights of shoes and clothing.

Long battery life

The battery life of the Genium is up to five days. Charging the joint is quick and simple, even through clothing.

Functionality

The best way to walk is with a natural, physiological gait – whether it be during a relaxed stroll through the city or walking quickly to the bus. It is exactly this gait that the Genium replicates almost identically, phase for phase. No matter on what surface, no matter at what speed. With the Genium, we have bundled this technology under the term "Optimised Physiological Gait" (OPG). It protects the entire locomotor system, improves wearer comfort and leads to noticeably more mobility in day to day life.

  • 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.
  • Adaptive yielding control
    Intelligent knee flexion control with full-surface contact between the prosthetic foot and the ground, depending on the forces acting on the prosthesis. You can 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.
  • 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.
  • Adaptive swing phase control
    The quality of the swing phase with the Genium 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 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.

With "Genium Gait Training", Ottobock has developed a training programme that instructs therapists, technicians and users in detail about conducting efficient gait training. 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 standing function, sitting with the Genium, climbing stairs step-over-step and much more. Numerous exercises have been selected to increase safety and confidence early on in using the Genium.

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 Vertical Shock

The Triton Vertical Shock provides additional shock absorption. It adapts very well to uneven terrain (e.g. forest floor). The forces acting on the residual limb while walking are therefore reduced, providing noticeable relief for the user.

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.
