Impact of Rehabilitation on Health Related Quality of Life in Patients with Hip Osteoarthritis

Hip osteoarthritis (OA) is a degenerative, progressive musculoskeletal system disease in adult individuals. Both genders demonstrate a similar prevalence at 11.5% for men and 11.6% for women. During the initial stage of hip OA, conservative treatments may significantly decrease pain, provide functional improvement and enhance health related quality of life (HRQoL).

The aims of the study were to evaluate the quality of life of patients with hip osteoarthritis and to estimate the impact of a comprehensive rehabilitation intervention on their HRQoL.

This was a prospective, observational study of 50 consecutive patients with hip osteoarthritis who were referred to an outpatient rehabilitation intervention. To assess their HRQoL before and after rehabilitation, we used the SF-36 and the Lequesne index for hip OA.

The mean age was 61.7±8.3 years, and 56% of the patients were women. After rehabilitation, the SF-36 RE and RP subscales and the Lequesne pain subscale showed the most significant improvement, although all of the SF-36 and Lequesne domains showed significant improvement. Before rehabilitation, the Lequesne ADL subscale was most correlated with the SF-36 PF subscale (rho=−0.908). After rehabilitation, the total Lequesne score was highly correlated with the SF-36 PF subscale (rho=−0.895). Age, education and the duration of disease were significantly correlated with all of the Lequesne subscales before and after rehabilitation.

This study showed that patients with hip osteoarthritis had a substantially low HRQoL, but all health dimensions showed statistically significant improvements after outpatient rehabilitation intervention.
