About the Polycentric Knee

The Circleg Polycentric Knee is designed to support users across a broad range of mobility levels, from basic household ambulation to active community walking. Its polycentric architecture provides enhanced stance-phase stability at heel strike while increasing ground clearance during swing phase, contributing to a safe and efficient gait pattern. An integrated extension-assist spring and flexion damper support smooth gait dynamics and predictable swing control. The knee allows flexion up to 150°, facilitating everyday activities such as sitting and navigating varied environments. A protective knee cap shields the mechanism from dust and dirt while providing a natural appearance in both standing and seated positions.
