This paper performed an analysis of education effect on physical rehabilitation in patients after total knee arthroplasty. The subjects of this paper were 142 patients who had visited two general hospitals located in Chungnam area. As a result of this study, for the change of arthroplasty status, the follow-up survey was estimated to be higher in the experimental group than control group, regardless of the time elapsed of 2 weeks after physical rehabilitation education. However, the physical activities were decreased by the education more rapidly with time elapsed of 8 weeks in the experimental group as compared to the control group. Therefore, the education for the improving physical rehabilitation in patients after total knee arthroplasty can be applied to any hospital.
