Clinical studies on knees 


In order of most recent publication first:


Sutherland, J., Sutherland, D., Kaufman, K. and Teel, M. Case Study Forum: Gait Comparison of Two Prosthetic Knee Units. J Prosth Orthot, 9, 168-173, 1997. 


Synopsis: The Total Knee demonstrated a slight initial knee flexion during stance, similar to non amputees. Walking velocity and stride length were improved with the knee and overall the gait parameters were more favorable with the Total Knee.


Johansson, S., Christiansson, B. and Karlsson, D. Gait analysis when comparing two polycentric kneejoint for amputees. Biomechanic Seminars, 7, 152-156, 1993. 


Synopsis: A comparison between Total Knee and OB 3R46. Downhill walking were performed with a higher speed for the Total Knee and the joint were considered to be more stable than the OB 3R46. Total Knee seemed to be the easiest knee to control.


Whitesides, T. E., Jr. and Volatile, T. B. Mauch S.N.S. hydraulic knee units in above-knee amputees. A long-term follow-up study. Clin Orthop, 264-8, 1985. 


Synopsis: 60 transfemoral amputees were fitted with the Mauch SNS hydraulic knee with a success rate of 93%. 47 patients were available for direct surbey and the clinical evidence have shown that the knee unit is superior to single axis device. The Mauch knee units are recommended for use in the active transfemoral amputees.


Volatile, T. B., Roberson, J. R. and Whitesides, T. E., Jr. The Mauch hydraulic knee unit for above knee amputation. Orthopaedics, 8, 229-30, 1985.


 Synopsis: The hydraulic Mauch knee were fitted to sixty one transfemoral amputees and only one rejected the knee for another device. A significant majority of the amputees stated that the Mauch knee unit gave them a smoother gait, ability to change cadence together with increased activity level and stability.
