Knee-foot synergy
Easy adjustment of heel height
Simple and efficient hydraulic unit


  • 1P50-R Hydracadence knee is a single axis hydraulic knee whose specific feature is a unique functional coupling between the knee and the ankle joint during flexion and extension movements.
  • At heel strike, the knee is in extension and simultaneously brings the ankle and therefore the foot into plantiflexion. Then flat foot is rapidly achieved, providing a high level of safety in slopes and uneven grounds.
  • When knee flexion reaches 20° during swing phase, the foot is actively lifted up in dorsiflexion, then lowered in the course of the walking cycle.
  • This raise of the forefoot provides an easy walk with no risk of the forefoot hitting the ground.
  • Carbon fiber frame
