CORRInsights®: Sonication of Arthroplasty Implants Improves Accuracy of Periprosthetic Joint Infection Cultures
There are a number of established diagnostic options for detecting the causative organisms in PJI, but preoperative arthrocentesis and intraoperative tissue cultures are the mainstays of diagnosis . In recent years, biofilm-dislodging technologies like sonication  or chemical dislodging using dithiothreitol  are gaining more-widespread use.
In their study, Rothenberg and colleagues examined the accuracy of sonication cultures during revision THA and TKA, and compared the results from preoperative arthrocentesis and intraoperative tissue cultures. The authors concluded that implant sonication cultures in arthroplasty revisions improves the detection of bacteria in both clinical and occult infections.
