title: Translation and cultural adaptation of the oxford hip score for Iranian population.
abstract: BACKGROUND
  In recent years, outcome assessment related to orthopedic surgeries has increasingly focused on patient-reported questionnaires. The Oxford Hip Score (OHS), self-administered questionnaire, is a reliable, valid, and responsive instrument for assessing hip in patients undergoing Arthroplasty.
  
  
  METHODS
  The study involved 105 adult Persian-speaking patients admitted for primary Total Hip Arthroplasty in two hospitals in Isfahan in Iran from September 2009 until April 2011. All of them filled out their scales (Persian OHS, WOMAC, and SF12) in preoperative examination.
  
  
  RESULTS
  Mean scores of OHS in first administrations was 42.7 ± 12.7. The Persian OHS overall score demonstrated high reproducibility (ICC,0.93, P < 0.001) and internal consistency (CA, 0.94). PersianOHS had high correlations with WOMAC total score (r = 0.86), function score (r = 0.86), and pain score (r = 0.79), the relationship between the Persian OHS and the WOMAC stiffness subscale was somewhat lower (r = 0.69). The correlation coefficient between the Persian OHS and the PCS of the SF-12 in our study was moderate (r = 0.58). Persian OHS had low correlation with MCS of the SF-12 (r = 0.40).
  
  
  CONCLUSIONS
  Persian OHS had high correlations with WOMAC total score, function score, and pain score. It had moderate correlation with PCS of the SF-12 and low correlation with MCS of the SF-12.
  
  
  CONCLUSIONS
  Our study demonstrated the trans-cultural adaptation and validation of the Persian OHS is a reliable and practicable instrument for assessment of function and pain in Iranian patients with hip osteoarthritis.
