Abstract
[Purpose] The aim of this study was to clarify the factors affecting the health-related quality of life (QOL) of knee osteoarthritis patients. [Subjects and Methods] The subjects were 115 knee osteoarthritis patients. Health-related QOL, JOA scores, subjective severity, and satisfaction with the surrounding environment, hobby activities, and family relationships, as well as economic condition, optimism index, age, gender, and the presence or absence of other joint diseases were surveyed in interviews. [Results] The four variables determined to be significant in multiple regression analysis of the SF-8 score were the JOA score, subjective severity, satisfaction with the surrounding environment and hobby activities. [Conclusion] The results suggest that when the objective and subjective severity of elderly knee osteoarthritis patients is low, and their satisfaction with the surrounding environment and hobby activities is high, their health-related QOL is also high.
