Analysis of Pharmacological Aspects Regarding Infection Free Survival After Surgical Treatment of a Periprosthetic Hip Infection: a Microdialysis Study
This study aims to use the technique of microdialysis to analyse the intraarticular space of the hip joint after removal of a periprosthetic joint infection affected endoprosthesis and implantation of an antibiotic-containing cement spacer over the entire period of the first hospitalization (usually 14 days) to closely monitor pharmacological and immunological aspects. In detail, antibiotic concentrations in the joint cavity and systemic circulation will be assessed according to reinfection rates, infection-free survival and fucntional outcome over a 12-month folluw-up period.

Inclusion Criteria:
* clinical indication for two-stage revision of hip PJI
* approval for surgery by the orthopedic and anesthesiologic department
* being over 18 years of age
* written, informed consent after detailed patient information about the study protocol and possible study dependent risks
Exclusion Criteria:
* \- known allergies to antibiotics gentamicin and vancomycin used within the spacer
Primary outcome measure(s)
Intraarticular concentrations of local antibiotics — Pre-Surgery (prothesis removal), during 14 days of hospitalization as well as pre-surgery of the reimplantation (approx. six weeks after the first surgery) Microdialysis will help to generate intraarticular hip joint samples after removal of an infectes prosthesis and spacer implantation. These samples will be analysed for spacer eluted antibiotics.
