# The hidden connection between gut microbiota and periprosthetic joint infections: a scoping review

## TL;DR

This paper explores the possible link between gut microbiota and joint infections after surgery, suggesting that gut health might influence infection risk.

## Contribution

The paper synthesizes existing literature to propose a novel connection between gut microbiome disruption and periprosthetic joint infections.

## Key findings

- There is emerging evidence suggesting a link between gut microbiome disruption and periprosthetic joint infections.
- Further research is needed to confirm the connection and understand its implications for prevention.
- The gut microbiome may influence pre-surgical risks and infection development.

## Abstract

Background: Periprosthetic joint infections (PJIs) pose a significant challenge in orthopedic surgery, and emerging evidence suggests that the gut microbiome may play a crucial role in their development and management. Despite the rarity of these infections, the continuous increase in prosthetic joint arthroplasties has made understanding how to prevent them more pressing. A stronger comprehension of the disruption of the gut microbiome and how this can lead to more of these infections and other pre-surgical risks may be crucial in preventing them. Objective: This article aims to provide a stronger understanding of the topic through the analysis of different pieces of already existing literature to help draw new conclusions and raise potential questions that need answering. Methods: A comprehensive search strategy without filters was employed, and multiple papers were thoroughly analyzed, understood, and compiled into this paper. Conclusions: Despite the limitations of some of the analyzed studies and finite evidence, this paper suggests that there could be a connection between periprosthetic joint infections and a compromised gut microbiome. However, further research is required to draw a definitive conclusion.
