This study aimed to define the PASS thresholds for generic and knee\u2010specific PROMs at 2 years after unicompartmental knee arthroplasty (UKA).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Prospectively collected data of 955 patients who underwent UKA for medial osteoarthritis at a single institution was reviewed. Patients were assessed preoperatively and 2 years postoperatively using the Knee Society Knee Score (KSKS), Function Score (KSFS), Oxford Knee Score (OKS), SF\u201036\u00a0Physical Component Score (PCS) and Mental Component Score (MCS). Responses to an anchor question assessing patients\u2019 overall rating of treatment results were dichotomized and used to determine if PASS was achieved. PASS thresholds for each PROM were selected based on the Youden index on a receiver operating characteristics (ROC) curve. Sensitivity analyses were performed for different subgroups (by age, gender, BMI), baseline score tertiles and an alternate definition of PASS.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In total, 92.7% reported their current state as acceptable. The areas under the curve (AUC) for ROCs were 0.72\u20130.83, except for the SF\u201036\u00a0PCS (AUC 0.64), indicating good discriminative accuracy of the other PROMs. PASS thresholds were 85.5 for KSKS, 77.5 for KSFS, 41.5 for OKS, 49.9 for SF\u201036\u00a0PCS and 54.6 for SF\u201036\u00a0MCS. Sensitivity analyses revealed that the thresholds were robust. Patients who attained a PASS were at least 4\u20135 times more likely to be satisfied and have expectations fulfilled.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>PASS thresholds can be used to define treatment success in future outcome studies. At the individual level, they provide clinically relevant benchmarks for surgeons when assessing postoperative recovery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of
