OSTEOARTHRITIS
Patient demographic information was obtained from the hospital’s database. Patients also completed the Short-Form 12 (SF-12), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and University of California Los Angeles (UCLA) Activity Score questionnaires preoperatively, and at 3 months, and 1 and 2 years postoperatively. Clinicians also completed the Harris Hip Score (HHS) evaluation for each patient at these visits.
