Materials and Methods

105 knees of 80 cases were tested after TKA surgery. 18 knees of 14 cases were men and 87 knees of 66 cases were women. The average age at the time of surgery was 71.5 years, and the average postoperative observation period was 25.5 months. All patients were with osteoarthritis of the knee. The use models were Hi-tech Knee II (Nakashima Medical, Okayama, Japan) CR type 99 knees and PS type 6 knees. The rate of return to work after surgery and employment rate of before and after surgery were examined for all cases. In addition,[1]age at surgery [2]ROM [3]JKOM score(Akai 2006) [4]Knee Society score (KSS Insall 1989) were examined in each case, and found the factors influenced on employment rate after TKA. The occupation was classified using major group of the International Standard Classification of Occupations (ISCO-08) defined by International Labour Organization (ILO) on 2007.
