A case report of total knee arthroplasty infected by Pasteurella multocida
Clinical Orthopaedics and Related Research
|May 1, 1978
Abstract:
A 72-year-old woman with a total knee prosthesis was infected with Pasteurella multocida organisms from a cat bite. The joint was successfully salvaged by surgical debridement, closed tube irrigation utilizing .25% acetic acid and appropriate antibiotics.
Insights
A cat bite led to Pasteurella multocida infection in a woman with a knee prosthesis. Prompt surgical debridement, irrigation with acetic acid, and antibiotics successfully saved the joint.
Area of Science:
- Infectious Disease
- Orthopedic Surgery
- Microbiology
Background:
- Pasteurella multocida is a common zoonotic pathogen, often associated with animal bites.
- Joint infections following animal bites, especially in patients with prosthetic devices, pose significant clinical challenges.
Observation:
- A 72-year-old female patient presented with a Pasteurella multocida infection of her total knee prosthesis.
- The infection was a direct consequence of a cat bite injury.
Findings:
- Successful joint salvage was achieved through a multi-modal treatment approach.
- Key interventions included surgical debridement, closed-tube irrigation with 0.25% acetic acid, and targeted antibiotic therapy.
Implications:
- This case highlights the importance of considering Pasteurella multocida in joint infections after animal exposure.
- Aggressive surgical management combined with antimicrobial therapy can preserve native joint function in complex prosthetic joint infections.
