Microprocessor Knees

Intelligent microprocessor (computerised) knees are more complex knee joints that are designed to help amputees walk with a much more stable and efficient gait that more closely resembles a natural walking pattern.

Benefits of Microprocessor (Computer-Controlled) Prosthetic Knees

The lack of trust in today's basic prosthetic limb often means that the user will shift their weight onto the non-amputated limb. This has a detrimental effect on other joints.

Microprocessor-controlled knees provide the amputee with more stability on all kinds of terrains, slopes and steps. Microprocessor-controlled knees, such as the Orion3, adapt hydraulic resistance in real time, providing the wearer with support whether they are standing still or moving.

Prevention of falls is just one aspect – reducing the chances of acute injuries – but effective stabilization can also cut down on medical problems often experienced by amputees with conventional prosthesis and joints, such as lower-back pain, arthritis and hip replacements.

Orion3 Microprocessor Knee

Orion3 is a water-resistant (IP-55) and intelligent microprocessor knee that uses Performance Response Technology to offer a very natural experience. It was built to offer the amputee stumble recovery technology; ensuring that the knee remains stable should the user falter. This, in turn:

    • Reduces the risk of amputees falling or injuring themselves when walking or changing environments
    • Provides users with the confidence and stability needed to move without fear
    • Reduces the lifelong care needs of amputees
    • Water-resistant (IP-55 rated)
