Revizyon Yapılan Enfekte Kalça Artroplastilerinde İntraoperatif Hipokloröz Asit Kullanımı

Aim: Arthroplasty infections are serious and difficult to treat complications. Hypochlorous acid (HOCl) is an oxidant produced endogenously in the body as a physiological part of the inflammatory process, with the aim of eliminating pathogens activated by neutrophils. The aim of this study was to evaluate the positive and negative effects on clinical results of HOCl used as an irrigation solution during surgical treatment. Material and Methods: The study included 37 patients who underwent single- or two-stage revision surgery at the University of Health Sciences Şişli Hamidiye Etfal Training and Research Hospital Orthopedics and Traumatology Clinic between January 2017 and December 2021. Treatment was applied according to our standard protocol of irrigation with 450 cc HOCl following implant removal and an additional 50 cc HOCl to the subcutaneous tissue after closing the fascia. The patients were evaluated during follow-up in respect of infections. Results: While single-stage revision surgery applied to 20 patients, two-stage revision surgery applied to 17 patients. 17 (45.9%) of the patients were male and 20 (54.1%) were female with a mean age of 72.8±11.1 years. The mean follow-up period was 25.8±14.1 months. Revision surgery was performed on one patient in each of the single and two-stage surgery groups. A success rate of 94.6% (n=37) was obtained when all patients were evaluated. Conclusion: The HOCl solution can be considered to make a positive contribution to the eradication of infections in revision hip arthroplasty and can be an effective and safe alternative to other irrigation solutions.
