4 BAR LINKAGE KNEE

4 BAR LINKAGE KNEE

A305

A 4-bar linkage knee with manual lock designed for low to moderate activity amputees.

PRODUCT FEATURES

Design & Hardware:

    • Constructed from lightweight aluminum to minimize the overall weight of the prosthesis.

    • Features a removable manual lock, allowing you to convert the joint from a locked stance knee to a free-swinging knee as the patient’s stability improves.

Indications & Fitting:

    • Offers a versatile choice of proximal adapters, making it suitable for both above-knee (transfemoral) and through-knee (knee disarticulation) amputation levels.

Swing Phase Control:

    • Utilizes adjustable axis friction to control the speed and resistance of the knee during the swing phase.

    • Equipped with an extension assist mechanism to help safely kick the lower leg forward into full extension before heel strike.
