Prosthetic joint infection (PJI) is often diagnosed from the tapped synovial fluid or from the culture of biopsy taken during the surgical procedures. These methods are often not sensitive.
When prostheses or part of it are extracted, they can be sonicated. It is a method that use ultrawave to remove biofilm from a surface (you can also use sonicatoin to clear your glasses by the way).
Among the advantages of sonication are:
1. It has high sensitivity, especially when the patient uses antibiotics and when the infection is caused by slow growing bacteria such as P. acnes.
2. It is simple to perform and the instrument is cheap (around 2000 euro per unit, that you might be able to pay with your salary and you can use the sonicator to clean your glasses... this is a joke folks.....).
For more infornation you can see the video that I upload in Youtube (with thank to Medical Microbiology Departement of Lausanne University Hospital that performed this procedure).
