Risk factors for infection after ankle fracture definitive fixation have been associated with open and\/or comminuted fractures and poorly managed diabetes. However, infection risk following pilon fractures have not been well studied, and the effect of infection on other postoperative outcomes have not been widely discussed. This study aims to identify risk factors for developing infection following pilon fracture and assess the effect of infection on postoperative outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>This study was a retrospective review of patients who presented with a pilon fracture and underwent surgical fixation between January 1, 2013, and June 1, 2023.
