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.
