3R60 - Knee prosthetics

Modular EBS Knee Joint

Be confident and keep going.

Thanks to easy initiation of the swing phase, the 3R60 knee joint allows you to walk at various speeds – whether you are going for a hike or strolling through a market. You benefit from a larger ground clearance during swing-through of the joint, reducing your risk of stumbling. The special joint design also gives you more stability in the stance phase and prevents unwanted flexion of the joint. The 3R60 also makes it possible for you to walk down gentle slopes.

Benefits at a glance
Walking well again
Walking well again

The forces acting on the residual limb, pelvis and spine are reduced, and the most natural possible gait pattern is achieved even at various walking speeds.

Enhanced safety
Enhanced safety

The knee joint can be selectively flexed with no delay regardless of the situation, providing you with enhanced protection in risky conditions.

Walking on uneven terrain and slopes
Walking on uneven terrain and slopes

Comfortable and safe walking even on rough terrain and slopes – for a reduced risk of stumbling.

Relaxed sitting and kneeling
Relaxed sitting and kneeling

Enjoy more freedom of movement. This is particularly handy when you get into a car, want to kneel down or have to sit in a confined space – when travelling on an airplane or train, during events or at the theatre.

EBS-PRO-Knee Joint

How does the EBSpro work?The mechanical principle of the EBSpro is based on the proven 3R60 prosthetic joint.The polycentric prosthetic joint has five axes that are arranged to form a ring. The anterior axis chain is designed like a conventional four-axis joint, but the posterior linkage bar is interrupted by an additional pivot point (Fig. 1). The proven design thus allows for two different modes of operation: swing phase mode and stance phase flexion mode. Two specially configured miniature hydraulic units (Fig. 2, A+B) control the two modes. Outstanding performance during the stance phase is the key feature of the 3R60.The spring and hydraulics combination in stance phase flexion mode is individually adjustable and can be precisely adapted to suit the requirements of the prosthesis wearer. Thanks to the progressive nature of the EBS resistance – realised with an auto-adaptive EBS unit – the effect can adapt itself over a large range of walking speeds for the first time.The higher the walking speed, the greater the extent to which flexion is limited. The lower the walking speed, the less damping resistance takes effect. This ensures greater stance phase flexion (Fig. 3). In this way, this important function adapts to various everyday situations. For the prosthesis wearer, this means enhanced safety and comfort as well as a highly natural gait pattern.

Knee prosthetics-3R80
3R80Knee prosthetics

Knee joint, monocentric, with rotation hydraulics

As a prosthesis wearer, you want to be confident that your knee joint meets your daily requirements and supports changing walking speeds. Through continuous further development, our goal is to offer you a knee joint that makes you as independent as possible in everyday life.The 3R80 with its unique rotation hydraulics principle is now also approved for prosthesis wearers with a body weight of up to 150 kg. With the 3R80, both the stance and the swing phase are controlled by the hydraulics. For example, walking down stairs step-over-step and walking down inclines are effectively supported by closely approximating a physiological gait pattern, even at various walking speeds. The 3R80 is water-resistant to a depth of 3 metres and has a manual lock for even better safety, especially in wet areas.
