Patient-reported outcome measures were used to describe the clinical characteristics of the population at baseline.The Hip Disability and Osteoarthritis Outcome Score (HOOS)10, the KOOS11, and the Oxford Hip Score and the Oxford Knee Score12,13 were used to assess pain, symptoms, activity limitations-daily living, sport and recreation, function, and hip- or knee-related quality of life.
The Short Form-36 survey14, the EuroQol 5-dimensional questionnaire, and the EuroQol Visual Analogue Scale15 were used to assess general health related quality of life. From the Short Form-36 survey, 2 summary component scores for physical health and mental health were calculated.
