Knee prosthetics

The waterproof, monocentric Aqua knee is compact, lightweight and equipped with miniature hydraulics and an integrated lock. Since safety is the top priority, mechanisms for standing securely are particularly important in wet areas. The 3WR95 Aqua knee is easy and straightforward to lock for activities in and around the water using the integrated locking mechanism.

The patented principle of rotation hydraulics already familiar from the 3R80 prosthetic knee joint is also used in a modified form in the 3S80 Sport. The rotation hydraulics in the 3S80=1 product variant contain oil with a lower viscosity than the standard 3S80 product variant. Due to its lower oil viscosity, the 3S80=1 is particularly well suited for applications demanding maximum ease of movement in the swing phase, for example sport prostheses for children or prostheses used for sprinting.

The 3R93 is a monocentric knee joint with a load-dependent brake mechanism and an optional locking function. An integrated, adjustable extension assist spring controls the swing phase.

The 3R92 monocentric knee joint with friction brake and pneumatic swing phase control has the same brake mechanism as the 3R90. The lower joint section is constructed as a pneumatic cylinder. To control the swing phase, the flexion and extension damping of the progressively acting dual-chamber pneumatics can be adjusted individually.

The Dynion was developed for active users who keep pace with life on their own terms and want a reliable partner in their everyday lives, for any situation.

The monocentric knee joint and its unique principle of rotation hydraulics allow users to closely approximate a physiological gait pattern, descend stairs step-over-step and walk down slopes. The 3R80 is a waterproof design for wet areas and is approved for a body weight of up to 150 kg.

The development of the 3R78 focused on a robust, dust-resistant design that is durable and resistant against environmental impacts. This polycentric prosthetic knee joint with pneumatic swing phase control offers reliable stance phase security for prosthesis wearers with moderate activity levels. In addition to the existing variant with proximal pyramid, other connection variants are now offered as well for users with a long residual limb (threaded connector) or knee disarticulation (lamination anchor, only included in the scope of delivery with the 3R78=KD). This allows an even larger group of patients to benefit from the advantages of this knee joint.

A rotation unit integrated into the lower joint section permits rotation of the prosthetic foot with automatic repositioning when the load is removed. Combined with the large flexion angle of about 179°, this makes a favourable kneeling position possible as well as crouching with the foot turned out.

The 3R60 Pro is a polycentric knee joint for users with a moderate activity level, featuring a relatively low net weight. The 3R60 and 3R60 Pro variants were respectively expanded with the EBS function (Ergonomically Balanced Stride), which enables controlled knee flexion at heel strike and provides high-performance hydraulic swing phase control. This ensures a wide range of walking speeds modelled after nature. The joint is available in four different connection variants.

The 3R41 is based on cutting-edge plastics technology and is suitable for users with a high need for safety. It is moisture-resistant, lightweight and especially low-wearing. You also benefit from the easy handling of the innovative release mechanism, which can even be operated under partial load.

The 3R39 is a monocentric modular knee joint with lock for children. The integrated locking mechanism secures the joint in the extended position. A lock cable protruding from the upper joint section is used to unlock the locking mechanism and permit flexion.
