Predictive Factors for Differentiating Between Septic Arthritis and Lyme Disease of the Knee in Children

Conclusions: Although septic arthritis of the knee and Lyme monoarthritis share common features that can make them difficult to distinguish clinically, the presence of pain with short arc motion, C-reactive protein of >4.0 mg/L, patient-reported history of fever, and age younger than 2 years were independent predictive factors of septic arthritis in pediatric patients. The more factors that are present, the higher the risk of having septic arthritis. Level of Evidence: Diagnostic Level III.
