title: The "Oxford Heup Score": the translation and validation of a questionnaire into Dutch to evaluate the results of total hip arthroplasty.
abstract: BACKGROUND
  The evaluation of a total hip prosthesis would be most complete if the opinion of the patient, surgeon and the radiographs are combined. Disease specific patient outcome questionnaires are scarce, especially in Dutch.
  
  
  METHODS
  The disease-specific 12-item questionnaire on the perception of patients with total hip replacement was translated into Dutch. We also investigated the extra value of two specific hip items, "the need for walking aids" and "sexual problems because of the hip", four general items on overall satisfaction and one question about patient classification. The 14 hip-specific items were each scored from 1 (least difficulties) to 5 (most difficulties). The Dutch translation, the "Oxford Heup Score" (OHS) was tested on psychometric quality in a multicenter prospective study.
  
  
  RESULTS
  The psychometric results of the OHS proved to be adequate. In the first postoperative year the score was very sensitive to changes, whereas in the second year it did not change significantly. The two added hip-specific questions were both filled out positively by more than 50% of the patients and thus fit perfectly into a hip-specific patient outcome questionnaire such as the OHS.
  
  
  CONCLUSIONS
  The OHS proves to be an appropriate instrument for assessment of the outcome of total hip replacement from the patient's perspective. Together with the judgement of the surgeon, it provides useful insights into the question of whether this operation has been a success or not.
