Superoxide solution irrigation for septic arthritis: a prospective clinical study of efficacy and a widened therapeutic window
Abstract
Background: Septic arthritis is an orthopedic emergency, with the knee being the most commonly affected joint. Standard irrigation with normal saline does not provide biofilm-disrupting efficacy, a key factor in treatment failure, especially against virulent organisms such as Staphylococcus aureus and Pseudomonas aeruginosa. This study evaluates the use of Hydrocyn, a superoxidized solution with known antibiofilm properties, as an intraoperative joint irrigant.
Methods: A prospective case series was conducted on 17 adults with native knee septic arthritis from 1 February 2024 to 31 December 2024. All patients underwent standard arthrotomy or arthroscopic washout with joint irrigation using Hydrocyn. Primary outcomes included serial measurement of inflammatory markers, including C-reactive protein (CRP) levels and white blood cell count (WBC), as well as knee range of motion (ROM) at baseline, 1, 2, and 6 weeks; ROM was further assessed up to 12 weeks postoperatively.
Results: Pathogens were identified in 94.1% of cases, including methicillin-resistant Staphylococcus aureus (MRSA) (17.6%) and P. aeruginosa (11.8%). Significant improvements were observed in CRP levels (p p = 0.001), and knee ROM (p < 0.001) at 6 weeks. The reoperation rate due to reinfection was 5.8%. Patients undergoing irrigation more than 24 h after admission demonstrated improvements in outcomes equivalent to those treated within 24 h, with no statistical difference between the groups.

How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health. Reported size: 17 participants or records.
