title: Hip Squeaking after Ceramic-on-ceramic Total Hip Arthroplasty.
abstract: OBJECTIVE
  The present study aimed to review the characteristics and influencing factors of squeaking after ceramic-on-ceramic (CoC) total hip arthroplasty (THA) and to analyze the possible mechanisms of the audible noise.
  
  
  METHODS
  The data analyzed in this review were based on articles from PubMed and Web of Science.
  
  
  METHODS
  The articles selected for review were original articles and reviews found based on the following search terms: "total hip arthroplasty", "ceramic-on-ceramic", "hip squeaking", and "hip noise."
  
  
  RESULTS
  The mechanism of the squeaking remains unknown. The possible explanations included stripe wear, edge loading, a third body, fracture of the ceramic liner, and resonance of the prosthesis components. Squeaking occurrence is influenced by patient, surgical, and implant factors.
  
  
  CONCLUSIONS
  Most studies indicated that squeaking after CoC THA was the consequence of increasing wear or impingement, caused by prosthesis design, patient characteristics, or surgical factors. However, as conflicts exist among different articles, the major reasons for the squeaking remain to be identified.
