ABSTRACT
<p><b>OBJECTIVE</b>To explore the value of detecting bacterial 16S rRNA with 23S rRNA in the diagnosis of periprosthetic joint infection (PJI).</p><p><b>METHODS</b>A prospective study was conducted among 67 patients with previous total hip arthroplasty (THA) undergoing a reoperation for infection (23 patients) or aseptic loosening (44 patients). Bacterial 16S rRNA and 23S rRNA in the interface membrane were detected by real-time PCR and their value in diagnosis of PJI was assessed.</p><p><b>RESULTS</b>The 16S rRNA and 23S rRNA showed no significant difference in their power in the diagnosis of PJI. The detection of 16S rRNA/23S rRNA showed a higher sensitivity and a greater negative predictive value in PJI diagnosis than the detection of 16S rRNA+23S rRNA (95.7% vs 52.2%, P<0.01; 97.6% vs 79.6%, P=0.01). The specificity, positive predictive value, and accuracy of the 4 diagnostic strategies were not significantly different.</p><p><b>CONCLUSIONS</b>The diagnostic power of 16S rRNA and 23S rRNA was similar in detecting PJI. Compared with the diagnostic strategy with 16S rRNA+23S rRNA, 16S rRNA/23S rRNA is more sensitive in detecting PJI.</p>
