Abstract

The incidence of knee osteoarthritis has increased among the elderly in Japan. The Japanese lifestyle requires frequent joint flexion because Japanese regularly sit on the floor. The purpose of this study was to ascertain the association between quality of life (QOL) and living conditions of Japanese patients one year after total knee arthroplasty. Patients who underwent total knee arthroplasty at two hospitals in Japan were surveyed. The questionnaire included the EQ−5D quality of life instrument and the Oxford Knee Score (including knee pain and activity), and it asked about the difficulty of performing deep (such as sitting on the floor) and living conditions. The questionnaire also assessed the use of a bed, table, and chair before and one year after surgery. Subjects were 139 patients (24 males, 115 females; mean age: 73.9 years (SD ± 7.1). Although QOL improved one year after surgery, patients had substantial difficulty performing deep flexion, and they had low scores for “sitting on tatami mats or the floor” and “using a Japanese−style toilet.” Hence, postoperative lifestyle changes resulted in an increased use of a bed, table, or chair. In additional, patients who used a bed, table, or chair had substantial difficulty performing deep flexion. Nursing interventions are needed to reduce the difficulty of performing deep flexion after surgery. 人工膝関節置換術患者の1年後QOL 053
