AB  - PURPOSE: To perform a systematic review of reporting trends and quantification 
      methods for the minimal clinically important difference (MCID) within the hip 
      arthroscopy literature. METHODS: Cochrane, PubMed, and OVID/MEDLINE databases 
      were queried for hip arthroscopy articles that reported the MCID. Studies were 
      classified as (1) calculating new MCID values for their specific study-population 
      or (2) referencing previously established MCID values. Data pertaining to patient 
      demographics, study characteristics, outcome measures, method of MCID 
      quantification, MCID value, anchor questions, measurement error, and study from 
      which referenced MCID values were obtained were extracted. RESULTS: A total of 59 
      articles with 18,830 patients (19,867 hips) was included. A total of 19 unique 
      outcome measures was reported. A total of 33 (n = 55.9%) studies (follow-up range 
      6-60 months) used previously established MCID values to assess their study 
      population (MCID values established at a follow-up range 6-31 months). The 
      remaining 26 studies (44.1%) performed new MCID calculations. The MCID values 
      were inconsistent and varied widely (Hip Outcome Score-Activities of Daily 
      Living: 5.0-15.4; Hip Outcome Score-Sports Subscale: 6-25; modified Harris hip 
      score: 2.4-20.9). Among the 33 studies that used previously established MCID 
      values, 10 different studies were cited as the reference. Among the remaining 26 
      studies that calculated a new MCID value, the most common method was 0.5 standard 
      deviation method (n = 21, 80.8%). Only 3 of 26 (11.5%) studies reported a 
      measurement of error in conjunction with their MCID values. CONCLUSIONS: 
      Inconsistencies in MCID reporting and quantification methods led to a wide range 
      of MCID values for commonly administered outcome measures within the hip 
      arthroscopy literature-even for the same outcome measures. The majority of 
      studies referenced previously established MCID values with variable ranges of 
      follow-up and applied those values to assess their specific study population at 
      varying follow-ups. LEVEL OF EVIDENCE: IV, systematic review.
