Changes in the Management of Periprosthetic Joint Infection Over the Past 50 Years

Vollständiger Abstract

Worum geht es in dieser Arbeit?

➢ Periprosthetic joint infection (PJI) remains a major complication of joint arthroplasty, associated with morbidity and health-care burden. Although room for progress remains, the management of PJI has evolved over the past 50 years from empiric, procedure-centered approaches to structured, evidence-based, and biologically informed strategies. ➢ This article summarizes key developments in the prevention, diagnosis, and treatment of PJI, driven by advances across multiple clinical and scientific subspecialties. ➢ Diagnostic approaches have advanced from reliance on clinical findings and culture to a multimodal framework integrating validated criteria, serological and synovial biomarkers, and molecular techniques. Surgical management has similarly evolved toward individualized strategies, including debridement with implant retention, 1-stage or 2-stage revision, and salvage surgery tailored to host, pathogen, and disease characteristics. ➢ Advances in microbiology, particularly the recognition of biofilm and the emerging role of the human microbiome, have further reshaped the understanding of PJI. Overall, this article examines how developments in prevention, diagnosis, surgical treatment, and microbiology have driven a transition toward precision-based, biology-informed, and individualized management of PJI.
