The Hip Disability and Osteoarthritis Outcome Scores (HOOS) was measured for Investigational Hard-on-Hard Total Hip Replacement Device only and included 40 items with five responses from five subcategories of Pain, Symptoms and Stiffness, Activities of Daily Living, Function in Sports and Recreational Activities, and Quality of Life to produce a total HOOS. The total HOOS scale ranged from 0 to 100, with 0 indicating the worst possible score and 100 indicating the best possible score.
