Although there is no universally accepted definition of prosthetic joint infection, criteria listed have been applied in a number of studies and have been recently summarized in the references publication. The criteria include the presence of at least one of the following:

  • Acute inflammation on histopathological examination of periprosthetic tissue, or
  • Sinus tract communicating with the prosthesis, or
  • Gross purulence in the joint space, or
  • Isolation of the same microorganism from multiple cultures of joint aspirates or intraoperative periprosthetic tissue specimens and/or in significant amounts from prosthesis sonicate.
