Is There a Threshold Value of Hemoglobin A1c That Predicts Risk of Infection Following Primary Total Hip Arthroplasty?

The risk of infection in patients with DM increases as the perioperative HbA1c increases. However, in the present study, the HbA1c threshold level calculated demonstrated low discrimination based on our AUC value, suggesting the HbA1c test is poorly predictive of periprosthetic joint infection following THA in patients with DM.
