Investigating how gut bacteria affect knee osteoarthritis through epigenetic changes

Official title: Cartilage Microbial Products as Novel Drivers of Knee Osteoarthritis Epigenetic Dysregulation

Funded at Oklahoma City VA Medical Center · NIH-10975940 · Data updated 2026-11-12

This study is looking at how changes in the bacteria in our gut, which can happen as we get older or gain weight, might affect knee osteoarthritis, and it’s for people with knee OA who are having surgery to replace their knee.

Who could benefit from this research

Could help

Ideal candidates for this research are individuals aged 65 and older who are experiencing knee osteoarthritis.

Less likely to help

Patients who are younger than 65 or do not have knee osteoarthritis may not benefit from this research.

What this research studies

This research aims to explore the relationship between changes in the gut microbiome due to age and obesity and their impact on knee osteoarthritis (OA). By analyzing samples from patients with OA and healthy individuals, the study will examine how these microbiome changes are reflected in the knee cartilage and other joint areas. The researchers will focus on understanding the epigenetic alterations that may arise from microbial influences, potentially leading to new insights into OA development and treatment. Patients undergoing total knee replacement will provide paired samples for this investigation.

Why it matters

Potential benefit: If successful, this research could lead to new strategies for preventing or treating knee osteoarthritis by targeting the gut microbiome.

How similar studies have gone: Previous studies have shown promising results in understanding the gut microbiome's role in osteoarthritis, suggesting that this approach could yield valuable insights.
