TI  - Meaningful values in the Short Form Health Survey-36 after total knee 
      arthroplasty - an alternative to the EuroQol five-dimension index as a measure 
      for health-related quality of life : minimal clinically important difference, 
      minimal important change, patient-acceptable symptom state thresholds, and 
      responsiveness.

AB  - AIMS: To identify the responsiveness, minimal clinically important difference 
      (MCID), minimal clinical important change (MIC), and patient-acceptable symptom 
      state (PASS) thresholds in the 36-item Short Form Health Survey questionnaire 
      (SF-36) (v2) for each of the eight dimensions and the total score following total 
      knee arthroplasty (TKA). METHODS: There were 3,321 patients undergoing primary 
      TKA with preoperative and one-year postoperative SF-36 scores. At one-year 
      patients were asked how satisfied they were and "How much did the knee 
      arthroplasty surgery improve the quality of your life?", which was graded as: 
      great, moderate, little (n = 277), none (n = 98), or worse. RESULTS: Physical 
      function, role limitations due to physical problems ('role physical'), bodily 
      pain, and the total score SF-36 scores demonstrated the greatest effect sizes (> 
      0.9). The MCID for each of SF-36 dimensions ranged from 1.7 for role emotional to 
      6.4 for bodily pain. The MICs for a cohort of patients ranged from -1.0 for 
      general health to 11.1 for bodily pain. The MICs for an individual patient were 
      marginally greater (one to two points) compared to those for a cohort, and 
      ranging from 0.0 for general and mental health to 13.5 for physical function. The 
      lowest PASS score threshold was associated with physical function (> 34 points) 
      whereas the greatest threshold (> 69 points) was associated with mental health. 
      CONCLUSION: The SF-36 is a responsive tool, and the estimates for MCID, MIC, and 
      PASS thresholds that can be used to power studies, assess whether there has been 
      a meaningful change in patients' health-related quality of life, and can be used 
      as a marker of achieving patient satisfaction following TKA. Cite this article:
