#67 – Nixing the Nidus: Managing Retained Sources in Prosthetic Joint Infections

Dr. Laura Certain (@laura_certain) and Dr. Nico Cortes-Penfield (@Cortes_Penfield) join Dr. Julie Ann Justo (@julie_justo) to discuss all things related to prosthetic joint infections. Tune in to learn about what comprises a bacterial biofilm, how it develops, and ways to combat it using the latest evidence-based antibiotic regimens. We also take a look at what’s on the horizon for the field of orthopedic infectious diseases.
