Comparison of synovial D-lactate with leukocyte count and polymorphonuclear neutrophil percentage. A and C The ROC curves of synovial biomarkers for the diagnosis of PJI. The AUC of synovial D-lactate, SF WBC count and SF PMN%. 0.87, 0.80 and 0.88, respectively. B The distributions (median and IQR) of synovial D-lactate, SF WBC count and SF PMN% in PJI and aseptic group. Dotted lines represent the optimal. Threshold based on the current study. D Sensitivity and specificity of synovial D-lactate, SF WBC count and SF PMN%. E PPV and NPV of synovial D-lactate, SF WBC count and SF PMN%
