Optimised Physiological Gait (OPG) thanks to sensor technology

It makes all the difference

Unique technology that enables a natural gait pattern

A natural gait pattern is the key to an enhanced sense of well-being and greater self confidence. Thanks to integrated Optimised Physiological Gait (OPG), our Genium and Genium X3 microprocessor knee joints give you a smooth walking pattern which relieves your entire musculoskeletal system.


Move confidently, wherever you are

Jenny loves rambling through her home on the North Sea coast in the Netherlands. Whether she’s strolling along the harbour with her granddaughter or exploring a wide variety of landscapes with her dog, Noah, the world-leading OPG technology in her Genium microprocessor knee joint gives her the best support for sustained walking on uneven terrain as well as side steps and walking backwards.

Walking longer distances is routine

As a surgeon, John covers several kilometres between the A&E unit, operating room, doctor’s room and canteen when he’s on-call. Thanks to the OPG technology in his Genium X3 microprocessor knee, he doesn’t have any problem finding the stamina he needs for his busy day. He is supported in particular by the ability to switch intuitively between different walking speeds and manoeuvre in small spaces, such as those between patients’ beds.

A free and independent life

Following her transfemoral amputation, Réka was determined to bounce back. She put incredible dedication into her rehabilitation so she could live a free and independent life again. Thanks to the OPG technology in her Genium microprocessor knee joint, she now has a natural, inconspicuous gait pattern that is almost indistinguishable from anyone else’s. For Réka, it’s important to be able to go out with her friends without attracting any attention, but also be able to show off her prosthesis at other times if she wishes.


PreFlex: effective impact absorption thanks to preflexion of the knee

A natural gait pattern requires smooth sequences of motion. The goal of electronic knee prostheses is to imitate these sequences in a way that’s as natural as possible. So far, just two electronically controlled knee joints in the world feature the OPG technology that offers anatomical preflexion of the knee prior to heel strike. Thanks to this preflexion, those who wear the Genium and Genium X3 also benefit from impact dampening which is equally effective and healthy for the body.

Adaptive yielding control: The right amount of knee flexion in every situation

Thanks to OPG technology, the Genium and Genium X3 can support users with a precisely calculated knee flexion. This feature works on various surfaces and slopes as well as in situations in which the user’s weight is increased because they are carrying objects such as suitcases or backpacks, or wearing heavy footwear. The Genium and Genium X3 also adapt to these changes in conditions in real time, which is something other joints cannot do.

Safer on the go thanks to Dynamic Stability Control

The prosthetic knee joint must flex at the moment in which the body’s weight is transferred to the sound leg – at the exactly the right time. A feature called Dynamic Stability Control monitors the gait cycle and detects exactly the right time to initiate knee flexion. Thanks to this function, the Genium and Genium X3 are significantly superior to other joints. Users find that the precisely calculated flexion moment is an additional safety factor, even during short sequences of steps.

Adaptive Swing Phase Control minimises risk of stumbling

A precisely measured flexion angle is important for the swing phase control. Thanks to the Adaptive Swing Phase Control feature in the OPG control program, this angle is always achieved – regardless of the walking speed, clothing or weight of the user’s footwear. Users enjoy a high level of safety thanks to this functionality, which has been proven to reduce the risk of stumbling and falling.

Reclaim your strength. Genium

You can do without people focusing a misplaced sense of concern on you. That’s why you want a knee joint that lets you lead a low-profile life without any noticeable physical issues. This includes a natural gait pattern which allows you to focus on your surroundings and the people around you. An electronically controlled Genium knee joint with OPG technology could be just the solution you’ve been looking for.
