    BackgroundPatient-reported outcome measures (PROMs) are important aspects of evaluating clinical outcomes after total knee arthroplasty (TKA). The patient-satisfaction score in the 2011 Knee Society Score (KSS) is one of the most frequently used questionnaires; however, patient satisfaction is a subjective assessment and is affected by multiple factors. Therefore, we evaluated correlations between the patient-satisfaction score in the 2011 KSS and that of other categories of the 2011 KSS as well as other PROMs. Furthermore, the ceiling effects of each PROMS were also investigated.MethodsWe enrolled 85 patients aged ≥65 years who underwent cruciate retaining TKA. Patients completed various questionnaires, including the 2011 KSS, Forgotten Joint Score-12 (FJS-12), EuroQol 5 Dimension (EQ-5D), and Geriatric Locomotive Function Scale (GLFS-25), one year after TKA. Simple linear regression analysis was used to evaluate correlations between each PROM and the patient-satisfaction score in the 2011 KSS. Ceiling effects of the patient-satisfaction score in the 2011 KSS, FJS-12, EQ-5D and GLFS-25 were evaluated by comparing the number of patients categorized into the top 10% with each PROM.ResultsAll scores were significantly correlated (p < 0.001) with the patient-satisfaction score in the 2011 KSS (symptoms: r = 0.69, functional activities: r = 0.69, patient expectations: r = 0.73, FJS-12: r = 0.72, EQ-5D: r = 0.67, GLFS-25: r = -0.74). The patient-satisfaction score in the 2011 KSS and GLFS-25 showed a ceiling effect. On the other hand, this effect was not observed in the results of the FJS-12 and EQ-5D.ConclusionsThe patient-satisfaction score in the 2011 KSS correlated with other PROMs, and the indicated level of satisfaction was consistent. The results of the FJS-12 and EQ-5D had good positive correlation to patient satisfaction without ceiling effect.Copyright © 2021 The Japanese Orthopaedic Association. Published by Elsevier B.V.
