      KSS and SF-12 scores after open-wedge high tibial osteotomy.

AB  - PURPOSE: Defining a Minimal Clinically Important Difference (MCID) value for 
      Patient-Reported Outcome Measures (PROMs) is crucial for determining the 
      effectiveness of a procedure and calculating the sample size for trial planning. 
      The purpose of this study was to determine the MCID of several PROMs (Knee injury 
      and Osteoarthritis Outcome Score (KOOS), Knee Society Score (KSS) and the SF-12) 
      in patients who underwent medial opening-wedge High-Tibial Osteotomy (owHTO) with 
      Patient-Specific Cutting Guides (PSCGs), using anchor-based methods. METHODS: 
      Patients undergoing isolated medial owHTO with PSCGs between January 2013 and 
      January 2017 were enrolled in this single-center, prospective, observational 
      study. Three outcome scores were collected pre-operatively and at the 2 years 
      follow-up evaluation: KOOS, KSS and SF-12. The MCIDs were calculated using 
      anchor-based method: at 2 years postoperatively: "Compared with before surgery, 
      how would you rate operated joint now?" The responses were recorded using a 
      five-point scale. Patients who answered "about the same" or "somewhat worse" were 
      classified into the no change group, while those who answered "somewhat better" 
      were classified into the minimal change group. A receiver operating 
      characteristic (ROC) curve was used to define the cutoff point that best 
      discriminated between the minimal change and no change groups for each PROMs 
      RESULTS: 196 patients were included, 75 (somewhat better) and 24 patients (about 
      the same and somewhat worse) were, respectively, assigned to the "no change" and 
      "minimal change" groups. There was no significant difference between the two 
      groups in terms of baseline characteristics and postoperative complications. At 
      24 months follow-up all the PROMs (KOOS, KSS and SF-12) were significantly better 
      for the "minimal change" group compared to the "no change" group. MCID was 15.4 
      for KOOS pain, 15.1 for KOOS symptoms, 17 for KOOS ADL, 11.2 for KOOS 
      sports/recreation, 16.5 for KOOS QQL, 3 for KSS symptoms, 5.6 for KSS activity, 
      7.2 for SF-12 physical component and 6.3 for PCS mental component. CONCLUSION: 
      This study determined the MCIDs of common used PROMs in patients undergoing 
      owHTO. LEVEL OF EVIDENCE: Prospective Cohort Study, Level II.
