Abstract
As techniques in hip arthroscopy are rapidly advancing, patient-reported outcome (PRO)
measures are becoming an integral part of measuring treatment effectiveness. The movement
toward developing valid and reproducible outcome measurement tools has shifted from
the traditional physician-derived data to patient-centered scores. As a result, the
current standard for measuring the effectiveness of any surgical treatment is to use
an outcome that reflects the patient's perspective. This review highlights the quality
of the questionnaire properties and their application to the patient undergoing hip
arthroscopy. Although the Modified Harris Hip Score (mHHS) has historically been used
as the traditional outcome measure for hip surgery, new PRO tools in the field have
been developed. The Nonarthritic Hip Score (NAHS) was intended for the younger, active
patient to assess hip pain and function without radiographic findings. The Copenhagen
Hip and Groing Outcome Score (HAGOS) and Hip Disability and Osteoarthritis Outcome
Score (HOOS) both incorporated hip related quality of life measures. The Hip Outcome
Score (HOS) was developed to assess the treatment outcomes of hip arthroscopy in young-to-middle-aged
individuals. Finally, the International Hip Outcome Tool-33 (iHOT-33) addresses the
outcomes of treatment in young active patients with hip disorders, in conjuction with
the multicenter arthroscopy of the hip outcomes research network. Among the available
literature comparing PROs in this patient population, the iHOT-33, HOS, and HOOS remain
reliable, valid, and consistent available PRO tools for hip arthroscopy surgery.
