Abstract

It has been reported that oestrogen receptor alpha (ER-α)polymorphisms are associated with knee osteoarthritis (OA).In this study, we assessed whether there was any association between the codon 594 (G>A) polymorphism in ER-α and radiographic features of OA or patient function. Radiographs, WOMAC score and patient reported time of symptom onset were assessed in 194 patients presenting for total knee replacement at Ramathibodi hospital over a one year period. ESR-1 genotyping was assessed. There were107 (55.15%) patients with common homozygote (GG), 78(40.20%) patients with heterozygote (GA) and nine (4.65%)patients with rare homozygote (AA). There was poor correlation (r =
