Risk of infection in primary, elective total hip arthroplasty with direct anterior approach or lateral transgluteal approach: A prospective cohort study of 1104 hips

The direct anterior approach (DAA) is increasingly popular for hip replacement. However, the small incision and the location near to the groin might increase the risk of periprosthetic joint infection (PJI). We asked the questions (i) whether there is an increased risk of infection for this approach, and (ii) whether the spectrum of microorganisms differs between patients with DAA and those with lateral transgluteal approach (LAT).
