Peri-prosthetic joint infections (PJIs) following total joint arthroplasty (TJA) are associated with higher treatment costs, longer hospital admissions and increased morbidity and mortality. Colonization with Staphylococcus aureus is an independent and modifiable risk factor for PJIs and carriers of S. aureus are ten times more likely than non-carriers for post-operative infections. Screening and targeted decolonization, vs universal decolonization without screening, remains a controversial topic. We recommend a tailored approach, based on local epidemiological patterns, resource availability and logistical capacity. Universal decolonization is associated with lower rates of SSI and may reduce treatment costs.
