title: Preoperative diagnosis of periprosthetic joint infection: role of aspiration.
abstract: OBJECTIVE
  The purpose of this article is to illustrate how total knee arthroplasty (TKA) and total hip arthroplasty (THA) aspiration by the radiologist can assist the health care team in determining the presence or absence of periprosthetic joint infection.
  
  
  CONCLUSIONS
  The increasing incidence of periprosthetic TKA and THA infection, as well as the changing role of aspiration for diagnosing periprosthetic joint infection, will likely increase demand for this important procedure in the future.
