Modulating Micrococcal Nuclease-Triggered Antibiotic Releases for One-Stage Revisions of <i>Staphylococcus aureus</i> -Infected Prostheses

at the time of uncoated primary intramedullary pin insertion, could not be resolved after one-stage revision without a proper pin coating, consistent with clinically observed challenges. However, bacterial burdens were significantly reduced following a one-stage revision with intramedullary pins coated with ampicillin-releasing coatings, with the combination of rapid and more sustained releases proving the most effective. When the combination coating was augmented with a single systemic vancomycin injection at the time of revision, infection was eradicated, outperforming local or systemic treatment alone and achieving unprecedented revision outcomes.
