Transfemoral prosthesis system with 3R60 EBS knee joint

The 3R60 EBS is a multiaxial, hydraulically controlled knee joint. Based on the natural model, it supports controlled knee flexion under load while walking.

Two miniature hydraulic units control flexion resistance in the knee joint

Benefits at a glance

Able to walk easily again

Controlled stance phase flexion up to 15° relieves strain on both limbs. The reduction of forces acting on the residual limb, pelvis and spine makes it possible to approximate a sound, physiological gait pattern.

Crouching down

Low weight and a very large flexion angle of 175° for greater freedom of movement – especially handy when you have to get into a car, or sit in a confined space in an airplane or train.

Reduced risk of tripping

Thanks to the multi-axial joint design, the prosthesis shortens during swing-through – effectively reducing the risk of tripping.

Walking on slopes

Comfortable walking with higher safety, even on rough terrain and on slopes of up to 10°.

Reduced risk

The design offers greater protection in high-risk situations: the wearer can always flex the joint in a controlled manner without delay, so there is less risk of falling than with locking knee joints.

Various walking speeds

Straightforward control of the swing phase and the virtually natural pendulum movement of the lower leg lead to a harmonious, natural gait pattern, even at different walking speeds.

The 3R60 Pro knee joint

The 3R60 Pro is based on the same principle as the 3R60 EBS – but it has been modified in several ways.

The 3R60 Pro is smaller, more compact and lighter than the 3R60 EBS, and is suitable for users with a maximum body weight of 75kg.

Progressive stance phase damping controls flexion and extension movements under load even more effectively. Especially at high walking speeds, when the acting forces are even higher compared to a slow or moderate walking speed.

Ideal component combination

Nature as the model

The Trias prosthetic foot made of carbon fibre has proven itself as a sturdy, high-quality everyday foot for users with moderate activity levels. Its triangular, curved shape reflects the anatomy of the human foot – making it a distinctive example of how nature’s solutions can be transferred to orthopaedic technology. The heel and forefoot elements replicate the arch structure of the human foot. The base spring connects them with each other in order to guarantee that the Trias works as a single unit.


The impact at heel strike is gently dampened, followed by a physiological rollover. The energy stored in the system at heel strike is released again at toe-off. Safe, controlled, energy-saving movement patterns boost the user's confidence in the prosthesis. The foot adapts to different walking speeds and uneven ground without loss of comfort while simultaneously reducing the load on the sound limb.

In addition to the normal version (10 mm heel height), the Trias footshell is also available in a slim version (20 mm heel height). This allows you to select from a greater variety of shoes.
