The most challenging complication after total joint replacement is the periprosthetic joint infection (PJI). Staphylococcus aureus is a commensal bacterium and a human pathogen. It is responsible for more than half of the PJI. We demonstrated that synovial fluid has antimicrobial properties against S. aureus and the iron restriction is one of the mechanisms used for the host to prevent bacterial growth, and is even able to increase killing of S. aureus. We have shown a clear role of transferrin as a restrictive factor in synovial fluid that functions by iron starving the bacteria and sensitizing them to killing …
