Abstract :	[en] Objective To assess health-related quality of life (HRQOL) in a prospective study with 7 years of follow-up in 49 consecutive patients who underwent a total joint replacement because of osteoarthritis. Methods Generic HRQOL was assessed with the shortform 36 (SF-36) and specific HRQOL with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Results Out of the 39 subjects who have completed the 7 years of follow-up of this study, 22 (56.4 %) underwent a hip replacement surgery and the other 17 (43.6 %) a knee replacement. Six months after surgery, a significant improvement, compared to preoperative scores, was observed in two of the eight dimensions of the SF-36 (i.e. physical function and pain). The same dimensions, pain and physical function, at the same time, 6 months after surgery, measured by the WOMAC, showed a significant improvement as well, but there was no significant change in the stiffness score. From 6 months to the end of followup, changes in SF-36 scores showed a significant improvement in physical function (p = 0.008), role-physical (p = 0.004) and role-emotional (p = 0.01) while all scores of the WOMAC improved (p\0.001 for pain, p\0.001 for stiffness and p\0.01 for physical function). Conclusion The improvements observed in HRQOL at short term after surgery, are at least maintained over a 7-year follow-up period.
