Summary
This study on deep joint replacement infections found that synovectomy and closed irrigation successfully eradicated infection in most patients without component removal. Long-term oral antibiotics prevented recurrence, offering a viable treatment for deep joint infections.
Area of Science:
- Orthopedic Surgery
- Infectious Disease Management
Background:
- Deep infection following total joint replacement presents a significant challenge in orthopedic surgery.
- Management often involves component removal, leading to prolonged recovery and potential complications.
Observation:
- Ten patients (twelve joints) with deep infections post-total joint replacement were analyzed.
- Surgical intervention included synovectomy and closed irrigation in seven patients, preceding culture results.
Findings:
- Successful eradication of infection without component removal was achieved in six of seven patients treated with synovectomy and irrigation.
- Long-term oral antibiotics (two years) were administered, resulting in no recurrence.
- Component removal was necessary in four patients; one required arthrodesis due to failed irrigation, and three showed radiographic loosening.
Implications:
- Synovectomy and closed irrigation represent a potentially effective conservative approach for managing deep periprosthetic joint infections.
- Early intervention with this method may help preserve joint components and improve patient outcomes.
- Further research is warranted to optimize antibiotic regimens and patient selection for this procedure.
