Summary
Hematogenous infection of total knee arthroplasty can occur from unusual causes like animal bite wounds. Early identification and treatment with penicillinase-resistant penicillin are crucial for eradicating Pasteurella multocida infections.
Area of Science:
- Orthopedic surgery
- Infectious diseases
- Microbiology
Background:
- Total joint arthroplasty infections are a significant complication.
- Hematogenous spread is a common route of infection.
- Bite wounds represent an unusual etiology for arthroplasty infections.
Purpose of the Study:
- To highlight Pasteurella multocida as a rare cause of total knee arthroplasty infection.
- To emphasize the importance of recognizing bite wounds as an inciting event.
- To recommend prompt prophylactic treatment for such infections.
Main Methods:
- Literature review of Pasteurella multocida infections in total knee arthroplasty.
- Analysis of case reports and clinical data related to bite wound infections.
- Review of antimicrobial susceptibility patterns for Pasteurella multocida.
Main Results:
- Pasteurella multocida, an oral bacterium in mammals, rarely infects total knee arthroplasties.
- Bite wounds are an uncommon but significant source of these infections.
- Penicillinase-resistant penicillins are effective prophylactic agents.
Conclusions:
- Prompt recognition of Pasteurella multocida knee arthroplasty infections is essential.
- Prophylactic treatment with penicillinase-resistant penicillins offers the best chance for eradication.
- Awareness of unusual etiologies like animal bites improves patient outcomes.
