Introduction:
Periprosthetic joint infection (PJI) is a major complication after total knee arthroscopy. Enterobacter is a rare cause of PJI.
Case Presentation:
We present a 65 year old Caucasian man who presented with acute right knee PJI with Carbapenem-resistant Enterobacteriaceae (CRE) two months after undergoing right knee intra-articular mass removal with endoprosthetic reconstruction. The periprosthetic joint infection (PJI) was treated with revision with 1-stage static spacer and IV meropenem.
Discussion:
CRE is an uncommon cause of PJI, but when it does occur, it commonly infects patients who are immunosuppressed or have specific risk factors. For an immunocompetent patient with CRE PJI, we suggest further workup for other systemic disease.
Conclusion:
This case demonstrates the importance of early diagnosis and treatment of CRE joint infections and the need for a multidisciplinary approach that includes aggressive surgical intervention and tailored antimicrobial therapy.
Insights
Carbapenem-resistant Enterobacteriaceae (CRE) can cause rare but serious periprosthetic joint infections (PJI) after knee surgery. Early diagnosis and a multidisciplinary approach are crucial for effective treatment of these challenging infections.
Area of Science:
- Orthopedic Surgery
- Infectious Diseases
- Microbiology
Background:
- Periprosthetic joint infection (PJI) is a significant complication following total knee arthroscopy.
- Enterobacter species are infrequent causes of PJI.
Observation:
- A 65-year-old immunocompetent male developed acute right knee PJI with Carbapenem-resistant Enterobacteriaceae (CRE) two months post-operatively after intra-articular mass removal and endoprosthetic reconstruction.
- The patient was treated with revision surgery involving a 1-stage static spacer and intravenous meropenem.
Findings:
- CRE is an uncommon etiology for PJI, typically affecting immunocompromised individuals or those with specific risk factors.
- This case highlights a CRE PJI in an immunocompetent host, suggesting the need for further systemic disease evaluation.
Implications:
- This case underscores the critical need for prompt diagnosis and management of CRE joint infections.
- A multidisciplinary strategy, incorporating aggressive surgical intervention and targeted antibiotic therapy, is essential for successful outcomes in CRE PJI.
