About the score:

Originally published in 1969 in the Journal of Bone and Joint Surgery, the Harris Hip Score (HHS) was designed to be a standardized assessment of patients following total hip arthroplasty. Since that time, it has also been used for evaluating patients following hip fractures and the diagnosis of osteoarthritis.

The HHS is a physician-completed instrument that consists of subscales for pain severity (1 item, 0-44 points), function (7 items, 0-47 points), absence of deformity (1 item, 0-4 points), and range of motion (2 items, 0-5 points). Scores range from 0 (worse disability) to 100 (less disability).
