Preoperative psychological distress has been reported to predict poor outcome and patient dissatisfaction after total hip replacement (THR). We investigated this relationship in a prospective multi-centre study between January 1999 and January 2002. We recorded the Oxford Hip Score (OHS) and SF36 score preoperatively and up to five years after surgery and a global satisfaction questionnaire at five year follow up for 1039 patients. We dichotomised the patients into the mentally distressed (Mental Health Scale score - MHS <50) and the not mentally distressed (MHS (50) groups based on their pre-operative MHS of the SF36. 776 (677 not distressed and 99 distressed) out of 1039 patients were followed up at 5 years.Introduction
