Short summary
Sinus tracts communicating with the prosthesis demonstrated high specificity and support their use as a confirmatory criterion for periprosthetic joint infection (PJI).

Both findings were associated with distinct microbiological patterns and less favourable outcomes, highlighting their clinical relevance.
