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

4R57Adapter
After a leg amputation, patients want to ensure that they can resume their usual everyday activities under the best possible conditions even with a prosthesis. This primarily requires the ability to perform turning and rotation movements of the knee joint. Ottobock has developed a rotation adapter for this purpose which makes everyday life easier for you in a number of ways. Next to sitting in comfort, activities such as putting on socks and shoes or driving a car are more convenient as well. For example, you can swing your prosthesis out of the way while driving, which not only provides more space in the footwell but also prevents the prosthetic foot from getting caught in the area of the pedals. Furthermore, the rotation adapter allows you to cross your legs and even sit cross-legged.The 4R57 rotation adapter is approved for a body weight of up to 150 kilograms and is now also available in a waterproof version. Your orthopaedics specialist will be happy to advise you regarding your specific requirements.

3R60-PROKnee prosthetics
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.
