Satisfaction, OKS

Age, sex, BMI, Primary diagnosis, ASA score, Index of Multiple Deprivation, OKS, EQ. 5D

Strongest determinants of outcome: pain/function (less severe preop disease obtain best outcomes); diagnosis in relation to pain outcome (RA > OA); deprivation (poorer areas = worse outcomes); anxiety/depression (=worse pain)

WOMAC
