The presence of a positive blood culture should be regarded a risk factor for DAIR failure in cases of haematogenous total knee arthroplasty infection

Key Points

• To determine the significance of positive blood cultures as a risk factor for DAIR failure in patients with hematogenous total knee arthroplasty infection.
• Level III study design assessing cases of haematogenous total knee arthroplasty infections.
• Evaluation of blood culture results and DAIR outcomes.
• Statistical analysis of the relationship between blood culture positivity and DAIR failure.
• Positive blood cultures correlated with a higher rate of DAIR failure.
• Identified blood culture positivity as a significant risk factor for poor outcomes.
• Suggests the need for enhanced clinical vigilance in affected patients.
