AB  - PURPOSE: The aim of this article was to highlight various terminologies and 
      methods of calculation of minimal clinically important difference (MCID) and 
      summarize MCID values of frequently used patient-reported outcome measures 
      (PROMs) evaluating total knee arthroplasty (TKA). MATERIALS AND METHODS: PubMed 
      and EMBASE databases were searched through May 2019. Of 71 articles identified, 
      18 articles matched and underwent a comprehensive analysis for terminologies used 
      to indicate clinical significance, method of calculation, and reported MCID 
      values. RESULTS: MCID was the most common terminology (67% studies) and 
      anchor-based methods were most commonly employed (67% studies) to calculate it. 
      The analytical methods used to calculate and the estimated values of MCID for 
      clinical use are highly variable. MCID values reported for WOMAC scores are 20.5 
      to 36.0, 17.6 to 33.0 and 12.9 to 25.0 for pain, function and stiffness 
      sub-scales, respectively, and 4.7 to 10.0 for OKS. CONCLUSION: There was lack of 
      standardization in the methodology employed to calculate MCID in the available 
      studies. MCID values reported in this review could be used for patients 
      undergoing TKA, although caution is advised in their interpretation and 
      application.
