Infected endoprosthesis in patients with rheumatism

Abstract

Infections are a severe complication after an artificial joint replacement. The clinical symptoms are highly variable, particularly in patients with inflammatory rheumatic diseases, which often makes the diagnosis difficult. In addition to clinical and laboratory findings, joint puncture is an essential component of the diagnostics and enables the identification of pathogens. Treatment of periprosthetic infections in patients with rheumatism should be an interdisciplinary cooperation between surgeons, rheumatologists and specialists for infectious diseases. The two essential pillars of treatment are surgical intervention and antibiotics. For acute joint infections an attempt at preservation of the artificial joint can be carried out, whereas for chronic infection situations only replacement of the prosthesis is possible as a curative treatment. In order to reduce the probability of occurrence of a joint infection, modifiable risk factors should be preoperatively identified and specifically treated.
