Official Title: Early Diagnostics of Septic Arthritis and Periprosthetic Joint Infections With Calorimetry and Polymerase Chain Reaction (PCR) of Synovial Aspirate Fluid
Brief Summary: The purpose of this study is to analyze pre- and intra-operative joint aspirates of native joints and joints with suspicion of periprosthetic joint infection (PJI) of the hip, knee and shoulder acquired in clinical routine. Joint aspirates are then analyzed with new diagnostic methods (microcalorimetry, PCR, alpha-defensin, etc.). Diagnostic speed and accuracy of these methods is compared to standard diagnostic methods in clinical routine, such as blood cultures of joint aspirates, cell count/differential, intra-operative tissue culture and histology and sonication.
