Periprosthetic Joint Infection as a Socio-Economic Problem of Modern Orthopedics

Periprosthetic joint infection is the main social and economic problem of modern orthopedics with a recurrence rate of chronic forms of up to 23.2–31.5%. The aim of this review is to inform various specialties doctors about the features of pathogenesis, etiology and treatment of periprosthetic joint infection, which significantly differ it from of other surgical site infections. The severity of infectious complications is due to the suppression of the patient’s immune system and microbial biofilms. Surgical treatment of periprosthetic joint infection involves debridement with preservation or removal of the implants, resection arthroplasty and arthrodesis. Today, in the treatment of more than 80% of cases of chronic infection, a two-stage approach is used, which allows to restore joint function after an average of 1.0–1.5 years. An integral part of the treatment of patients is high-dose, long-term and combined antibiotic therapy, which allows you to effectively deal with the leading pathogens of periprosthetic infection Staphylococcus aureus and S. epidermidis, the share of which is 46.5–57.5%. In the conditions of growing resistance of bacteria to antibiotics, the interest of researchers in the possibilities of using bacteriophages in the complex therapy of infections of bones and joints has increased. The cost of treatment exceeds the cost of “aseptic” joint replacement by 2–24 times and is characterized by a high level of disability and mortality of patients. Taking into account the numerous factors affecting the course and effectiveness of complex treatment of patients with periprosthetic infection, a multidisciplinary approach is currently considered the main component of success. The medical and social significance and high financial costs of treating patients with periprosthetic infection indicate the need for further research and the active implementation of effective scientific developments in the practical healthcare system.
