Patient-reported outcome measures (PROMs) are frequently used and recommended to support clinical decision-making, health policies, and reimbursement processes. The are many hip-specific PROMs to choose from, and clinicians should be aware of them and select the one(s) that best suit their purpose and patient hip pathology. This chapter will describe each hip-specific PROMs and detail their psychometric properties and intended use. In the context of athletes with hip musculoskeletal injuries, the HAGOS and iHOT tools seem to be the most adequate and suitable PROMs. The NAHS and HOS may be other useful hip-generic PROMs to assess patients with non-arthritic hip pathologies. In the setting of patients with hip osteoarthritis, the clinician may opt from several tools, but we recommend the HOOS or mHHS instruments. Finally, where applicable, the clinician may also apply a health-related quality of life PROM, such as the SF-36 or the EQ-5D to assess the psychological and emotional status of the patient.
