AB  - BACKGROUND: Despite the innovations in total knee arthroplasty (TKA), there is 
      still a subset of patients who do not acquire significant relief or expected 
      satisfaction after primary TKA. However, this subgroup of patients still gains 
      improvements more or less in terms of objective or quantified assessments after 
      the procedure. The purpose of our study is to explore the factors that correlate 
      with patients' satisfaction and identify minimal clinically important difference 
      (MCID) and minimum important change (MIC) in clinical parameters. METHODS: We 
      conducted a retrospective study of 161 patients diagnosed with osteoarthritis who 
      underwent unilateral total knee arthroplasty from January 2017 to December 2017. 
      We collected the following parameters: body mass index (BMI), duration of 
      disease, education level, depression state, preoperative flexion contracture 
      angle of knee, HSS scores, 11-point NRS scores, and radiological parameters 
      (preoperative minimal joint space width and varus angle of knee). The 
      satisfaction was graded by self-reported scores in percentage (0-100). RESULTS: 
      We revealed that 80.8% of patients were satisfied 3 years overall after primary 
      TKA. HSS score change, NRS-Walking score change, age, and pre-mJSW showed 
      significant difference between satisfied and dissatisfied group. The varus angle 
      change revealed statistical significance according to the levels of satisfaction. 
      Simple linear regression identified the MCID for HSS score to be 5.41 and for the 
      NRS-Walking to be 1.24. The receiver operating characteristics (ROC) curve 
      identified the MIC for HSS score to be 25.5 and for the NRS-Walking score to be 
      6.5. CONCLUSIONS: In summary, we identified several factors that correlated with 
      patients' satisfaction independently after TKA in a long term. In addition, we 
      revealed the minimal clinically important difference (MCID) and minimum important 
      change (MIC) for HSS and NRS score in these patients.
