3R31 - Knee prosthetics

Prosedo monocentric locking knee joint, with hydraulic sitting assist


Users with lower mobility appreciate our Prosedo knee joint for deliberately supporting their efforts to sit down.
Featuring a hydraulic sitting assist function our mechanical locking knee Prosedo 3R31 is best suited for older users. An individually adaptable (according to body weight) hydraulic sitting assist makes it easier for them to sit down on a bed or chair. After releasing the manual lock, the flexion resistance deliberately supports the sitting down procedure. The user may then shift his/her weight equally on both legs – the prosthetic leg and the sound leg. This not only leads to an improved balance, but also reduces the strain on the unaffected side.

CPO explains that the Prosedo knee supports safe sitting-down through a high resistance
High degree of safety

The Prosedo is the worlds’s first semi-automatic locking knee 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 lower mobility, the Prosedo provides secure and comfortable wearing.

Elisabeth is talking to the CPO about the Prosedo.
Confidence due to more balance

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 prosthetic limb – when unlocking the knee joint to sit down.

The knee enables Elisabeth to distribute her body weight equally on the sound and the amputated side.
Stability thanks to individually adjustable hydraulic

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.

Elisabeth is talking to the CPO, wearing the Prosedo locking knee.
Meeting the patients’ 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, the small and lightweight design and two connector versions make the knee joint suitable for many amputees, including those with long residual limbs.
