The world’s first mechanical semi-automatic knee lock with hydraulic sitting assist
The 3R31 Prosedo knee joint allows low mobility amputees to regain their ability to stand and walk short distances. The joint provides targeted support for sitting down with the added benefits of security and comfort. When you disengage the lock, a high resistance is initiated.
You feel more balanced, more confident and the pressure on your sound limb is reduced.

What you need to know
Advantages for you
The 3R31 Prosedo is the world’s first semi-automatic knee lock with an adjustable hydraulic cylinder. This hydraulic cylinder supports safe sitting-down through a high resistance once the lock is disengaged. Suitable for amputees with reduced mobility, the Prosedo provides secure and comfortable wearing.
When walking, the Prosedo knee joint is locked in extension, however for sitting down the lock is able to be disengaged via the lock release cable. Unlocking is possible under partial load, resulting in more balance and safety. An even weight distribution can be maintained on both the sound and amputated limbs when unlocking the knee joint to sit down.
Integrated Hydraulic Unit
The integrated hydraulic unit stabilises wearers when the lock is disengaged and actively supports them in the process of sitting down. When sitting down, the knee enables the wearer to distribute their body weight equally on the sound and amputated side, providing relief and security. The resistance is individually adjustable, according to the wearer’s weight and needs.
The Prosedo knee is able to be fitted to transfemoral, knee disarticulation and hip disarticulation patients. Prosedo’s high maximum weight level of 125kg, small and lightweight design and two connector versions make the knee joint suitable for many amputees, including those with long residual limbs.
