[Review] Role of gut microbiota disruption in prosthetic joint infection: a scoping review

Prosthetic joint infection (PJI) is a serious complication of joint replacement surgery. Emerging evidence suggests that gut dysbiosis (characterised by reduced microbial diversity, altered immune responses, and increased intestinal permeability) could facilitate bacterial translocation from the gut to prosthetic joints and contribute to the development of PJI. In this scoping review, we analysed eight studies (three preclinical and five clinical) that investigated the potential link between gut microbiota alteration (dysbiosis) and PJIs.
