Short summary
We examined whether the way hip replacement is performed affects the types of bacteria that can cause early infection. By reviewing records of 187 patients who needed follow-up surgery due to infection, the researchers found that the surgical technique did not influence which bacteria were present. They also found that body weight had no effect. These results suggest that newer, less invasive surgical methods as the direct anterior approach do not increase infection risks from specific bacteria.
