Boldfaced values are statistically significant (P < 0.05). HOS-ADL, Hip Outcome Score–Activities of Daily Living subscale; HOS-SS, Hip Outcome Score–Sports subscale; iHOT-12, international Hip Outcome Tool–12; MCID, minimal clinically important difference; PASS, patient acceptable symptomatic state.
