Pneumatic, Polycentric, 5-Bar Knee Joint on Bearings KK-S953 — a premium component for prosthetic-orthotic systems from the manufacturer KEN DALL. This polycentric knee joint (ID: 43808) is designed to provide natural and safe biomechanics during walking, combining a complex five-bar construction with pneumatic actuation for precise movement regulation.

Description and Purpose

The pneumatic polycentric joint KK-S953 is developed as part of medical equipment and prosthetic-orthotic components and is suitable for complex custom knee prostheses where smooth shock absorption, reliable extension support, and fine-tuning of flexion and extension parameters are required. Thanks to the polycentric design, movements acquire a maximally natural trajectory profile, which increases user comfort and safety under load.

Key Features and Benefits

• Bearing-based construction — ensures durability, smooth movement, and reduced mechanism wear.
• Effective heel shock absorption — reduces impact load transfer to the prosthesis and residual limb, enhancing walking comfort.
• Independently adjustable pneumatic flexion and extension control — allows fine-tuning of the joint's behavior to the patient's individual needs.
• Stance stability adjustment — an option to increase safety during standing and the stance phase of walking.
• Extension support — guarantees reliable fixation in the extended position under load, reducing the risk of unexpected flexion.

This joint is ideal for use in prostheses for users with medium to high activity levels, where controlled damping, adaptability to various walking speeds, and component durability are important. The manufacturer KEN DALL ensures a high level of material quality and mechanical precision, making the KK-S953 a reliable choice for clinics, prosthetic workshops, and individual prosthetists.

Usage Recommendations

For optimal performance of the pneumatic joint, regular maintenance and checking of the pneumatic circuit's integrity are recommended. Pneumatic adjustments should be performed by a qualified specialist according to the user's weight and activity level to ensure a balance between walking comfort and stance stability.
