About the score:

Originally published in 2003 in BMC Musculoskeletal Disorders, the Hip Disability and Osteoarthritis Outcome Score (HOOS) assesses patient pain (10 items), satisfaction including stiffness and range of motion (5 items), activity limitations-daily living (17 items), sports and recreation function (4 items), and hip related quality of life (4 items). Scores range from 0 to 100 with a score of 0 indicating the worst possible hip symptoms and 100 indicating no hip symptoms. This is a patient reported joint-specific score, which may be useful for assessing changes in hip pathology over time, with or without treatment.
