A cat bite led to a rare Pasteurella multocida knee arthroplasty infection. Prompt antibiotic treatment is crucial for patients with prosthetic joints and pets, especially after bites.
Area of Science:
- Orthopedics
- Infectious Diseases
- Microbiology
Background:
- Pasteurella multocida infections are exceptionally rare in patients with joint arthroplasty.
- Domestic animal bites, particularly from cats, can introduce pathogens into prosthetic joints.
Observation:
- A patient with a knee arthroplasty developed a severe infection following a domestic cat bite.
- Clinical presentation included a putrid joint effusion, necessitating prosthesis removal.
Findings:
- Infection was confirmed to be caused by Pasteurella multocida.
- A two-stage revision surgery combined with intravenous antibiotic therapy was performed.
Implications:
- Prosthetic joint infections from pet-associated bites require increased clinical awareness.
- Patients with domestic pets and arthroplasty should be educated about potential infection risks.
- Prompt and thorough antibiotic treatment is vital following animal bites in this patient population.
