3R92 - Knee prosthetics

Knee joint with friction brake, monocentric, with pneumatic swing phase control

Always on the ball!

The 3R92 knee joint with friction brake is suitable for users with a moderate activity level and ensures safety in the stance phase. For you as a user, this means that the integrated brake activates when weight is placed on the heel and thereby stabilises the prosthesis. This results in high stance phase stability. When the load shifts back to the front of your foot, the braking mechanism deactivates automatically so you can initiate the swing phase more easily. Elevating the hip is not necessary to initiate the swing phase. In addition, the plastic covers protect the mechanical components of the joints while also shielding a foam cover, if used.

3R78Knee prosthetics
The 3R78 knee joint is lightweight yet robust and offers high stance phase safety for users with moderate activity levels. The joint geometry effectively shortens the prosthesis when your leg swings through, giving you more ground clearance. A large flexion angle of 150° also provides greater freedom of movement. The knee joint also supports you when walking at various speeds and is approved for a body weight of up to 100 kilograms.
