  1. MCID Minimal Clinically Important Differences, HHS Harris Hip Score, OHS Oxford Hip Score, VAS Visual Analog Scale
  2. aHHS scores are categorized as >90 excellent; 80-89 good; 79-79 fair and <70 bad [16, 29]. We defined a clinically relevant improvement as one category improvement
  3. bOHS scores are categorized as > 41 excellent, 34 -41 good, 27-33 fair, <27 bad [30, 31]. We defined a clinically relevant improvement as one category improvement
  4. cWe used a difference of 20 mm or more as clinically relevant improvement [34]
  5. dPrimary hip: HHS: 0.7% excluded because of ceiling. OHS: 1.5% excluded because of ceiling. VAS pain rest: 37.2% were excluded because of ceiling. VAS pain exercise: 4.5% were excluded because of ceiling
  6. eRevision hip: HHS: 4.9% excluded because of ceiling. OHS: 5.6% excluded because of ceiling. VAS pain rest: 28.2% were excluded because of ceiling. 10.9% were excluded because of ceiling
