Influence of environmental temperature and heatwaves on surgical site infection after hip and knee arthroplasty: a nationwide study.

Background: Previous studies reported higher incidence of surgical site infection (SSI) after procedures performed in summer or with high temperatures. However, no study used detailed climate data to assess this risk after hip and knee arthroplasty, and no study specifically investigated the role of heatwaves.

Aim: To assess the impact of higher environmental temperatures and heatwaves on SSI rates after hip and knee arthroplasty.
