Prosthetic joint infection: recent developments in diagnosis and management

Abstract

Over the past years there has been a significant increase in the number of joint prosthesis replacements worldwide. The most serious complication of joint prosthesis is infection with an incidence of 1.5-2.5% for primary interventions and up to 20% for revision procedures. The mortality rate ranges between 1% and nearly 3%. The economic cost of this complication is up to $50,000 per patient and $250,000 million per year. A major issue in the management of prosthetic joint infection (PJI) is the relative difficulty in making a diagnosis so to cause a significant effect on the prognosis. Goals of the treatment are to eradicate infection, prevent its recurrence and preserve mechanical joint function. In this review we focus on the value of traditional and newer diagnostic tests and we discuss management and preventive strategies. European networks are needed to define the best diagnostic and treatment strategies in order to reduce future challenge posed by PJIs.
