{Abstract}: <B>OBJECTIVE: </B>To calculate unstratified and patient-specific meaningful improvement (MI) and patient acceptable symptom states (PASS) for the WOMAC total score in patients after total hip (THR) or total knee replacement (TKR).<BR><B>METHODS: </B>A retrospective observational cohort study. Anchor-based receiver operator characteristics curves were used to estimate MI and PASS thresholds.<BR><B>RESULTS: </B>Recovery paths were specific to individual characteristics of patients. An unstratified 12-months MI threshold of 28.1 (PASS: 13.3) and 17.8 (PASS: 15.8) for patients after THR and TKR, respectively, would unfairly detect critical recovery paths.<BR><B>CONCLUSIONS: </B>Thresholds for treatment success need to be as patient-specific as possible.
