WOMAC: 8–item WOMAC functional subscale; SF–12 PCS: SF–12 Physical component score; SF–12 MCS: SF–12 Mental component score; Patients’ fulfilment score: mean percentage of individual expectations that have been fulfilled; Rho = Pearson’s correlation coefficient; Co–morbidities were measured using the Charlson comorbidity index. *p<0.05.
