AB  - AIMS: The aim of this study was to identify the minimal clinically important 
      difference (MCID), minimal important change (MIC), minimal detectable change 
      (MDC), and patient-acceptable symptom state (PASS) threshold in the Forgotten 
      Joint Score (FJS) according to patient satisfaction six months following total 
      knee arthroplasty (TKA). METHODS: During a one-year period 484 patients underwent 
      a primary TKA and completed preoperative and six-month FJS and OKS. At six months 
      patients were asked, "How satisfied are you with your operated knee?" Their 
      response was recorded as: very satisfied, satisfied, neutral, dissatisfied, or 
      very dissatisfied. The difference between patients recording neutral (n = 44) and 
      satisfied (n = 153) was used to define the MCID. MIC for a cohort was defined as 
      the change in the FJS for those patients declaring their outcome as satisfied, 
      whereas receiver operating characteristic curve analysis was used to determine 
      the MIC for an individual and the PASS threshold. Distribution-based methodology 
      was used to calculate the MDC. RESULTS: Using satisfaction as the anchor 
      question, the MCID for the FJS was 16.6 (95% confidence interval (CIs) 8.9 to 
      24.3; p < 0.001) and when adjusting for confounding this decreased to 13.7 points 
      (95% CI 4.8 to 22.5; p < 0.001). The MIC for the FJS for a cohort of patients was 
      17.7 points and for an individual patient was 10 points. The MDC90 for the FGS 
      was 12 points; where 90% of patients scoring more than this will have experienced 
      a real change that is beyond measurement error. The PASS was defined as 22 points 
      or more in the postoperative FJS. CONCLUSION: The estimates for MCID and MIC can 
      be used to assess whether there is clinical difference between two groups and 
      whether a cohort/patient has had a meaningful change in their FJS, respectively. 
      The MDC90 of 12 points suggests a value lower than this may fall within 
      measurement error. A postoperative FJS of 22 or more was predictive of achieving 
      PASS. Cite this article: Bone Joint J 2021;103-B(5):846-854.
