Short summary
This study performed an external validation of the so-called JS-BACH classification from 2021, which aims to help predict the outcome of periprosthetic joint infections using three groups of increasing severity. Using data from 249 patients, we found that higher severity scores were strongly linked to an increased failure rate. This simple tool could guide doctors in tailoring treatments and improving results for patients with these challenging infections.
