Should intraoperative purulence be considered as a definitive sign of a periprosthetic joint infection (PJI)?

Authors: Javad Mortazavi, Erik Hansen

RECOMMENDATION: Intraoperative purulence should not be considered a defi nitive sign of a PJI. The defi nition of purulence is subjective and is neither a sensitive, nor specific, diagnostic marker of a PJI. A validated, objective definition for purulence due to infection is required to set
purulence as a diagnostic criterion for PJIs.

LEVEL OF EVIDENCE: Moderate
