Hip pain and hip function are measured with the Hip<br /><br>disability Osteoarthritis Outcome Score (HOOS). Direct costs are measured with<br /><br>the modified Trimbos/iMTA Questionnaire for costs (TiC-P) questionnaire.<br /><br>Productivity costs are measured with the Productivity and Disability (PRODISQ)<br /><br>questionnaire. All scores are obtained at baseline and at 6 weeks, 3, 6, 9, 2<br /><br>months follow-up.</p><br>
