title: Total hip arthroplasty: differences in outcome measures between men and women.
abstract: BACKGROUND
  Patient-related factors impact the long-term survival of hip arthroplasty. This study evaluated whether there were differences in outcome measures between men and women undergoing total hip arthroplasty.
  
  
  METHODS
  A retrospective study of prospectively collected data on 75 primary total hip arthroplasties in 72 patients was conducted. Medical history, physical examination, Harris Hip scores, and Quality of Life forms (SF-36) were obtained for each patient preoperatively and postoperatively. Preoperative radiographs were assessed using the Kellgren and Lawrence scoring system. Only patients with a minimum follow-up of 2 years were included.
  
  
  RESULTS
  Preoperatively, women and men had comparable Kellgren and Lawrence scores and Harris Hip scores. Of the 8 subscores for the SF-36, only the Physical Functioning subscore was significantly different preoperatively. Similar results were noted postoperatively; again, only the Physical Functioning subscores were significantly different between men and women.
  
  
  CONCLUSIONS
  Physician assessments were not significantly different preoperatively and postoperatively for men or women. The results for the SF-36 were similar except for a significant difference in the Physical Functioning subscore preoperatively and postoperatively. According to the Medical Outcomes Trust, the SF-36 Physical Functioning score has been shown to be the best all-around measure of physical health.
