Summary

This study compared two types of surgical retractors used during hip replacement surgery to see if one caused fewer infections. 144 patients were randomly assigned to receive either a Charnley retractor or an Alexis O-Ring retractor. The researchers took tissue samples during surgery to check for contamination and followed patients for one month after surgery to track any infections or complications.
