  • Recommendation:
  • For trans-femoral amputees
  • With moderate functional levels
  • Moderate stance phase stability 
  • Moderate swing phase control 
  • Very suitable for longer stump lengths
  • Not Suitable for amputees with higher functional levels
  • Description:
  • The knee axis connects the upper and lower joint sections with bushings. Stance phase stability is achieved by placing the knee axis posterior to the weight-bearing line. Control of the swing phase is independently provided by the Extension Assist and by adjustment of the axis friction.
  • Technical Data: Knee flexion range: approx. 155 degrees, Height (knee centre- upper edge): mm
