Prosthetic joint infections (PJIs) generate significant clinical and socio-economic pressures on the health service. Recent advances in the diagnosis of PJIs, with biomarkers and sonification have aided delineation of PJIs from aseptic processes. However these investigations are not widely available and expensive. Interface membrane histology has been shown to be superior to pseudocapsule histology; we therefore sought to ascertain the diagnostic benefit of deep canal sample microbiology in conjunction with standard pseudocapsule sampling. We performed a prospective study over a 20-month period as part of new multi-disciplinary approach to the management of suspected PJIs. 22 patients underwent 26 procedures at our institution where intra-operative deep canal samples were obtained concurrent to conventional pseudocapsule samples. These samples were cultured and analysed following our standardised microbiological methodology.Introduction
