Local Antibiotic Infusion in Periprosthetic Joint Infection Following Total Hip Arthroplasty.

Local antibiotic infusion has emerged as a promising adjunctive therapy, delivering high concentrations of antibiotics directly to the infection site. This approach aims to enhance eradication of pathogens while minimizing systemic side effects associated with prolonged antibiotic use. This narrative review encompassed 10 articles focused on all three procedures of surgical intervention for periprosthetic joint injection (PJI) following total hip arthroplasty (THA): debridement, antibiotics, and implant retention (DAIR), single-stage revision arthroplasty, and two-stage revision arthroplasty. Recent studies report success rates ranging from 90 to 100% in patients undergoing DAIR, 82 to 100% in single-stage revision arthroplasty, and 80% in two-stage revision arthroplasty. The adjunctive use of local antibiotic infusion alongside surgical treatment for PJI following THA provides high success rates and is associated with low systemic complications, such as renal toxicity. Further research, particularly high-quality randomized controlled trials (RCTs), is warranted to validate and refine treatment protocols, ensuring consistent efficacy and safety.
