TWO-STAGE REVISION KNEE ARTHROPLASTY FOR THE TREATMENT OF INFECTION AFTER TOTAL KNEE ARTHROPLASTY AT VIET DUC UNIVERSITY HOSPITAL
Main Article Content
Abstract
Objective: To review the indications and evaluate the outcomes of two-stage revision knee arthroplasty for infection following total knee arthroplasty at Viet Duc University Hospital. Materials and Methods: Patients who underwent two-stage revision for periprosthetic joint infection after total knee arthroplasty at Viet Duc University Hospital from 2022–2025 were included. Descriptive study. Results: Four patients with chronic infection were analyzed (3 females, 1 male); mean age 67.25 ± 13.84 years (range, 54–82). Microbiology: Staphylococcus aureus in 75% (MRSA 50%, MSSA 25%); 25% were culture-negative. The typical systemic antibiotic regimen was vancomycin combined with gentamicin and ciprofloxacin/levofloxacin for 4–8 weeks; one culture-negative case received prolonged therapy for 1 year. After placement of an antibiotic spacer, all 4/4 patients underwent reimplantation with a hinged knee prosthesis once infection control was achieved. The latest functional outcomes were favorable: ROM ≈ 100°, VAS 0–4, and one patient required a walking cane. Conclusion: Two-stage revision achieved reliable infection control and favorable functional outcomes in this series (ROM ≈ 100°, VAS 0–4). Outcomes were influenced by pathogen type (notably MRSA), local soft-tissue condition, inflammatory markers, interstage interval, and adherence to antibiotic therapy.
