Development of a novel robot-assisted orthopaedic system designed for total knee arthroplasty

Abstract

Recently, the number of robot-assisted orthopaedic system which supports surgeon has increased. As one of the background, it is considered the difference between plan and result of the bone cutting is varied because the technique to resect bone is based on the ability of individual surgeon. And authors developed a robot to resect bone which has 9 degree of freedom, and as the result, the accuracy of bone cutting improved. Moreover, we developed a total operation system including pre-operative planning system and intra-operative assist system. © Springer-Verlag Berlin Heidelberg 2004.
