Polycentric prosthetic knee

Last crawled date: 1 year, 3 months ago

A polycentric prosthetic knee is a type of artificial knee joint used in prosthetics to replace a natural knee joint that has been lost or damaged. Unlike a simple hinge joint that only moves in one direction, a polycentric knee joint has multiple axes of rotation, allowing for a more natural range of motion.

The term "polycentric" refers to the fact that the joint has multiple centers of rotation, which allows it to mimic the complex movement of a natural knee joint. Polycentric knees typically use hydraulic or pneumatic components to control the movement of the joint and provide stability and support for the user.

Polycentric prosthetic knees are typically used for people with above-knee amputations or other conditions that require the replacement of the knee joint. They can improve mobility and stability, allowing users to walk more naturally and engage in a wider range of physical activities. However, they can be more expensive and require more maintenance than simpler hinge-style prosthetic knees.
