Above Knee prosthesis 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.

This means the user walks using minimum variation with the natural walking pattern and uses less energy while walking.

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.

3R60 prosthesis with max. flexion angle

Kneeling 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.

Crossing the street, safely overcoming curbs

Reduced risk of tripping

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

User walking down a slope.

Walking on slopes

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

User with the 3R60 on uneven ground

Reduced risk of stumbling

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.

1C30 Trias prosthetic foot

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 artificial limb. The foot adapts to different walking speeds and uneven ground without loss of comfort while simultaneously reducing the load on the sound limb.

Overview of the positive interplay between the 3R60 and the Trias


  • What amputation levels can be fitted with a 3R60 knee joint?

    The 3R60 is very versatile in application. Fittings for nearly all amputation levels from knee disarticulation, above knee, hip disarticulation and hemipelvectomy are possible.

  • What are the benefits of the 3R60?

    The 3R60 gives you great freedom of movement. It is possible to walk on slight inclines and uneven surfaces; thanks to the extremely large flexion angle, you can bend your leg very far and the risk of tripping and falling is reduced with the 3R60. You walk more naturally with the prosthetic knee joint; the swing phase, which you can initiate with little force, is harmonious.

  • Can I walk down stairs step-over-step with the 3R60?

    No, the 3R60 is not suitable for users who are physically able to go down stairs step-over-step. However, limited stance phase flexion under load makes it possible to walk down slight inclines up to 10° step-over-step.
