Preoperative gait metrics, age, sex, body mass index (BMI), and exercise participation were analyzed via multivariate stepwise linear regression for a relationship with 1-year postoperative patient-reported outcomes (PROs), including Hip Outcome Scale-Activities of Daily Living (HOS-ADL); HOS-Sports Subscale (HOS-SS), and 12-item international Hip Outcome Tool (iHOT-12).
