Hydraulic Motion Control Knee

Product Information

The Hydraulic Motion Control Knee (MCK) features hydraulic stance and swing control with smooth, automatic activation during normal walking. Its intelligent hydraulic yielding system engages when the knee is in a posterior-leaning position, providing controlled support even while clearing obstacles during swing. As the knee transitions into an anterior-leaning position during pre-swing, the yielding function disengages to allow for a smooth, natural swing phase. Once activated, hydraulic yielding remains engaged during activities such as descending stairs or walking downhill, offering controlled knee flexion for increased stability.
