Microprocessor Control System

Above the knee amputees require a knee joint and lower leg to ambulate. The knee joint and lower leg components attach to a socket. Custom sockets are created for each individual amputee and fit onto their residual limb using a number of systems and methods to stay in place.

The socket is created with a lock body at the bottom of the socket which attaches to a knee and or pylon (a metal tube) then down to the prosthetic foot. A below the knee amputee would have a pylon coming directly out of their socket which would then attach to their prosthetic foot. The completed device is known as a prosthetic or prosthesis. Every amputee is unique and they’re prosthetic should compliment their needs based on their activity level and ADL’s.

There are two general types of prosthetic knees: mechanical and microprocessor. The difference between a mechanical knee and a microprocessor knee lies in its functionality. Both devices have a hinge (and in some cases dual hinges) that replace the human anatomical knee joint. Mechanical knees operate using a hydraulic, pneumatic or friction-locking system, and the responsiveness of a given knee is often controlled by either air, oil, or friction, as well as the body-powered movements of the amputees themselves. By contrast, microprocessor knees are controlled by a computer system that actually learns an amputee’s walking patterns and can be programmed for specific types of use. Moreover, this system helps to physically push patients forward, offering a more stable and efficient gait that can help achieve a more natural walking pattern overall.

Microprocessor knees also feature software programs that enable professionals to easily set up the device and adjust the functionality to each user’s specific lifestyle requirements. In addition, these chargeable devices provide access to valuable activity reports and allow micro adjustments to ensure safety and stability. Because the microprocessor technology seamlessly detects your movements, it is especially helpful for traversing more difficult terrains, all while its adaptive capabilities help to prevent a stumble or fall. This device will respond to its surrounding environment in such a way that patients can more readily navigate slopes, stairs, tight spaces and more, maximizing the potential for users to continue on with their daily activities in a safe, efficient and dignified manner.
