Higher baseline expectations for TJR improved health-related quality of life, satisfaction
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.
Study results showed larger improvements in HRQoL at 12 months among patients who had higher pain relief or ability to walk expectations. WOMAC and SF-12 physical component summary domains also improved more among patients with high expectations regarding the ability to walk, interact with other and psychological wellbeing expectations, according to the researchers.
Patients with very high expectations on the SF-12 physical component summary regarding their ability to walk and with high or very high pain relief expectations on SF-12 mental component summary experienced better improvement compared with patients with low expectations, the researchers found.
The researchers also found patients who had high or very high daily activities expectations were more likely to be satisfied.
