ABSTRACT

Total knee arthroplasty is an increasingly common orthopedic surgical procedure, and infection is one of the most feared complications as it is the main cause of revision surgery. Its treatment is very difficult, prolonged and involves multiple specialties. The best prevention method is to identify the risk factors of the patient, the hospital environment and the surgical technique. The identification of the causal germ by means of a culture is crucial for effective diagnosis and treatment as the antimicrobial resistance associated with the biofilm makes treatment more complex. The main symptoms are pain, joint effusion, local heat, erythema, loss of range of motion, leakage of blood or pus from the surgical wound. The duration of symptoms is used to classify the infection, but the definition today is based on the criteria set by the Musculoskeletal Infection Society (MSIS). In addition to cultures, serological tests and imaging studies are used to diagnose and follow up during the treatment of periprosthetic infections. Treatment includes the use of intravenous antibiotics followed by oral therapy for several weeks, surgical cleaning and debridement, prosthetic replacement in one or two stages. Currently, two-stage revision surgery continues to be more successful in the treatment of total infected knee arthroplasty. Life-saving surgeries such as arthrodesis or amputation will always be the last option.
