Abstract

Insights

The gut microbiota influences bone health and infection risk after joint replacement surgery. Modulating gut bacteria may offer new strategies to prevent complications like aseptic loosening and periprosthetic joint infection.

Area of Science:

  • Orthopedic surgery
  • Microbiome research
  • Immunology

Background:

  • Revision surgery rates for aseptic loosening and periprosthetic joint infection (PJI) after hip and knee arthroplasty are increasing.
  • Novel strategies are needed to prevent revision surgery, reduce healthcare costs, and improve patient outcomes.
  • Modulating the gut microbiota is an emerging area of research for influencing bone health and systemic inflammation.

Purpose of the Study:

  • To review the role of the gut microbiota in bone health and PJI following total joint arthroplasty.
  • To explore the potential of gut microbiota modulation as a therapeutic strategy.

Main Methods:

  • A literature review of preclinical and clinical studies was conducted.
  • Articles focused on the gut microbiota's impact on bone health and PJI were analyzed.

Main Results:

  • The gut microbiota affects bone mineral density, influencing osseointegration, osteolysis, aseptic loosening, and fractures.
  • Gut microbiota impacts gut permeability and bacterial translocation, increasing PJI susceptibility.

Conclusions:

  • Emerging evidence links gut microbiota to aseptic loosening and PJI after total joint arthroplasty.
  • Microbial therapies like probiotics and fecal microbiota transplantation show potential for risk moderation.
  • Further research is necessary to validate these findings and therapeutic approaches.
