Abstract
Currently, the number of Total Knee Arthroplasty (TKA) in Japan is 70,000. Because it is easy to expect increasing the number due to super-aging society, the clinical outcome of TKA surgery has been important The surgery requires proper soft tissue balance to avoid shortening fatigue life of prosthesis. Thus, a measurement system of force concentration about contacting region between femur component and polyethylene insert contributes to prolong the prosthesis. This study examined the force concentration by using our developed measurement system. This study performed two experiment consists of physical and simulated experiment As a result, our developed system could localize the force concentration point A future work is to apply this measurement system to the cadaveric knee.
