Higher baseline expectations for TJR improved health-related quality of life, satisfaction

August 27, 2014

Health-related quality of life and satisfaction improved among patients who had higher expectations for total joint replacement at baseline compared with patients who had lower expectations, according to study results.

Researchers recruited 892 patients preparing for total joint replacement (TJR) of the knee or hip due to primary osteoarthritis. Before surgery and for 12 months afterward, patients completed questionnaires with five questions about expectations before surgery; an item to measure satisfaction; WOMAC and SF-12; and questions about sociodemographic information. The researchers performed general linear models and logistic regression analysis to determine the association of patients’ expectations at baseline with satisfaction and changes in health-related quality of life (HRQoL) 12 months after surgery.
