Implant – associated infections

The use of orthopedic implants has been increasing steadily in the last 50 years, but despite considerable technological advances including perioperative antimicrobial prophylaxis, implant-associated infections remain a serious complication. These infections are caused by bacteria in the biofilm on the implant surfaces.

Implant-associated infections such as periprosthetic joint infections or spinal implant-associated infections are a feared complication after orthopedic surgery. These infections are usually difficult to treat, because microorganisms persist in biofilms on the orthopedic implant surface. Therefore, it would be desirable to prevent these infections.

An improved prevention or – treatment an early diagnosis, is the main objective of this research area to reduce morbidity in implant-associated infections.
