Brucellar prosthetic arthritis in a total knee replacement
Summary
Brucella septic arthritis is a rare complication of prosthetic joint infections. Conservative three-drug antibiotic therapy successfully treated a total knee replacement infection in a 60-year-old man.
Area of Science:
- Infectious Diseases
- Orthopedic Surgery
- Microbiology
Background:
- Prosthetic joint infections (PJIs) are typically caused by staphylococci, streptococci, and gram-negative rods.
- Brucella spp. are an uncommon cause of PJIs, with few cases reported in medical literature.
- Standard treatment for PJIs involves antibiotics and surgical management, often including component removal or retention.
Observation:
- A 60-year-old male patient presented with septic arthritis in his right knee total knee replacement.
- The infection was diagnosed as Brucella septic arthritis, a rare presentation in prosthetic joints.
- The patient had a history of total knee replacement surgery.
Findings:
- Conservative management with a three-drug antibiotic regimen was implemented for the Brucella PJI.
- The patient experienced excellent clinical outcomes following the conservative treatment approach.
- No surgical intervention for component removal or retention was required.
Implications:
- This case highlights the possibility of Brucella spp. causing prosthetic joint infections.
- Conservative antibiotic therapy can be a viable and effective treatment for rare PJIs like Brucellosis.
- Further research may explore optimal antibiotic strategies for Brucella prosthetic joint infections.
