[ 5 ] - Staphylococcus aureus Colonization in Patients Undergoing Total Hip or Knee Arthroplasty and Costeffectiveness of Decolonization Programme
Background: Periprosthetic joint infection is a devastating complication of total joint arthroplasty. It seems that thepatient’s skin, nose, throat, and urine are important sites for microbial colonization. Colonization with staphylococcusaureus, especially methicillin resistant increases the risk of periprosthetic joint infection. The aim of this study was toassess the prevalence of staphyloco...
