HIPPO artificial intelligence: Correlating automated radiographic femoroacetabular measurements with patient-reported outcomes in developmental hip dysplasia

Table 1 Patient-reported outcome measures surveys

Survey	Description
HHS	The HHS is a joint-specific 10-question survey evaluating hip function. The survey parameters include- ability to climb stairs, take public transport, and put on shoes and socks. The test has been shown to have strong construct validity, and thus would be appropriate as a comprehensive assessment of the affected joint’s impact on the patient[16]
SF-12	The SF-12 survey, which was adapted from the SF-36 survey, assesses the patient’s view of their own health and how it relates to their lifestyle. It includes questions, such as asking the patient if they achieved as much as they have liked and whether they have felt calm and peaceful. Thus, the SF-12 can provide insight into the psychological aspect of the patient’s condition[20]
IHOT-12	The iHOT-12 is a 12-question survey adapted from the 33-question survey. The survey evaluates quality of life changes[21]
EQ-VAS	EQ-VAS is a scale from 0 (worst health) to 100 (best health) that allows the patient to indicate their overall perspective of their health state[22]

IHOT: International hip outcome tool; EQ-VAS: Visual Analogue Scale of the European Quality of Life Group; HHS: Harris hip score; SF: Short form.
