Link found between gut bacteria, successful joint replacement
A study by researchers at Cornell's College of Engineering and the Hospital for Special Surgery (HSS) shows gut microbiome health influences the risk of infection.The work was published recently in the journal Clinical Orthopaedics and Related Research, according to a university article.
“This research is in early stages, but if it pans out in humans, it's possible we could change or fix the patient's gut microbiome before they go in for hip or knee replacement and that could further reduce the risk of infection,” Christopher Hernandez, associate professor in the Sibley School of Mechanical and Aerospace Engineering and the Meinig School of Biomedical Engineering, said in the article.
Hernandez is the paper's first author and he is a BMES member.
Infections following joint replacement surgeries are rare, affecting only 1% of patients who have procedures, according to the article. However, infections are the No. 1 reason for replacing an artificial knee and the No. 3 cause for replacing an artificial hip.
In the study, the researchers used mice fitted with tiny artificial knees.
