The updated 3R106 prosthetic knee is designed to support natural movement in a wide range of everyday situations. Building on trusted performance, the updated version is lighter and has a lower build height for a more compact fit.
With an increased knee flexion angle of 172°, it makes everyday activities such as kneeling, sitting on the floor, reaching into low cupboards, or playing with children and grandchildren easier and more comfortable. Designed for moderately active users (mobility grade 2–3, up to 100 kg), it provides the stability and reliability needed for daily life.
The 3R106 is a mechanical polycentric knee with pneumatic swing phase control and a dual-chamber pneumatic unit, designed to support a wider range of walking speeds. Separate adjustment of flexion and extension damping allows for more precise tuning to individual needs, helping to create a smooth and controlled swing phase. Combining the compact design of the 3R106 with key functional benefits inspired by the 3R106-PRO, the 3R106 offers greater adaptability and confidence in everyday movement.

For stability and reliability.
Whether you are travelling to your next destination by train, kneeling in the garden, or playing on the floor with your children or grandchildren, the high knee flexion angle of the 3R106 helps support comfortable and natural movement throughout the day.
With the 3R106 knee joint, everyday movement feels more natural and manageable – whether you’re moving through narrow supermarket aisles, putting dishes away in kitchen cupboards, or making your way through a busy market.
The polycentric design of the 3R106 provides reliable stability during the stance phase and naturally shortens during swing, helping to increase ground clearance. This can reduce the risk of the foot catching on the ground and supports a smoother, more confident walking pattern.
Whether you’re in a hurry and need to pick up the pace, or prefer a slower stroll in the countryside, the 3R106 adapts to your individual walking speed and provides reliable support throughout.
