Blood markers may predict joint infection treatment success
NCT ID NCT07358455
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study will check if certain blood markers (like NLR and PLR) can predict how well people recover after surgery for a joint infection. Researchers will follow 200 adults who need a two-stage joint replacement revision. The goal is to find cheap, easy tests that help doctors plan better care and reduce the risk of infection coming back.
