AAHKS 2018 Annual Meeting press release; Dallas, November 3, 2018.
Press Release: A multi-institutional study examined the ability of next-generation sequencing (NGS) to identify the causative organism(s) in patients with PJI of the knee. Recent reports demonstrate that NGS facilitates pathogen identification in culture-negative PJI (CN-PJI); however, this signal has not been externally corroborated. From 13 academic institutions, samples from 102 TKA revisions were examined via NGS. NGS identified microbes in 9 of 10 culture-negative patient samples and 25 of 66 “aseptic” revisions; culture identified microbes in 4 of 66 samples. NGS was able to detect a pathogen in >90% of culture-negative cases and demonstrated a high rate of concordance with culture in culture-positive cases. The collaborative findings suggest NGS is a useful adjunct for identifying the causative organism in PJI, particularly in the setting of CN-PJI. Read Press Release
