Brief Summary

Study Type

Prospective, single-arm, open-label, multicenter (3 to 5 sites), interventional trial.

Primary Study Objective

The objective of the study is to determine the safety profile of local antibiotic irrigation for the treatment of PJI.

Primary Outcome Measure

The overall safety profile is characterized by assessing the incidence of adverse events (AEs), serious adverse events (SAEs), suspected adverse reactions, adverse reactions, and unexpected adverse reactions.

Follow-up

Patients will be assessed for all measures at 3 weeks, 6 weeks, 12 weeks, and 12 months from initial surgery.

Eligibility Criteria

Inclusion Criteria

• Patients in whom negative pressure wound therapy is contraindicated
• Patients infected with pathogens that are not considered susceptible to vancomycin HCl or tobramycin sulfate, as per the Investigator's opinion
• Breastfeeding at screening visit
