Patient-acceptable symptom state for the Oxford Hip Score and Forgotten Joint Score at 3 months 1 year and 2 years following total hip arthroplasty: a registry-based study of 597 cases

摘要

Background and purpose — Patient-acceptable symptom states (PASS) represent the level on a patient-reported outcome measure (PROM) at which patients are satisfied with postoperative outcomes. We defined the PASS for the Oxford Hip Score (OHS) and Forgotten Joint Score (FJS-12) at 3-month, 1-year, and 2-year intervals after primary total hip arthroplasty (THA).
