AB  - In this article, a new hydraulic semi-active knee (HSAK) prosthesis is proposed. 
      Compared with knee prostheses driven by hydraulic-mechanical coupling or 
      electromechanical systems, we novelly combine independent active and passive 
      hydraulic subsystems to solve the incompatibility between low passive friction 
      and high transmission ratio of current semi-active knees. The HSAK not only has 
      the low friction to follow the intentions of users, but also performs adequate 
      torque output. Moreover, the rotary damping valve is meticulously designed to 
      effectively control motion damping. The experimental results demonstrate the HSAK 
      combines the advantages of both passive and active prostheses, including the 
      flexibility of passive prostheses, as well as the stability and the sufficient 
      active torque of active prostheses. The maximum flexion angle in level walking is 
      about 60 degrees , and the peak output torque in stair ascent is greater than 60Nm. 
      Relative to the daily use of prosthetics, the HSAK improves gait symmetry on the 
      affected side and contributes to the amputees better maintain daily activities.
