Comparative Diagnostic Accuracy of Metagenomic Next-Generation Sequencing and Targeted Next-Generation Sequencing for Periprosthetic Joint Infection: A Systematic Review and Meta-Analysis

This meta-analysis indicates that mNGS demonstrates higher sensitivity and a numerically greater AUC than tNGS for diagnosing PJI, with acceptable specificity, although the difference in AUC was not statistically significant. Conversely, tNGS exhibits higher specificity and DOR, alongside acceptable sensitivity, making it valuable for confirming PJI. Overall, the diagnostic accuracy of both next-generation sequencing (NGS) methods is comparable, with each possessing distinct advantages and limitations.
