Objective. To assess impact of the COVID-19 pandemic on the structure of pathogens causing periprosthetic joint infection (PJI) and the dynamics of their antibiotic resistance.
Materials and Methods. A retrospective analysis of 379 strains of microorganisms isolated from patients with PJI of the knee and hip joints who underwent surgical treatment at the Federal Center for Traumatology and Orthopedics from 2018 to 2024 was performed. The biological material for the study was synovial fluid samples, tissue biopsies, aspirates from removed implants after ultrasonic treatment.
