Risk-stratified association between dilute povidone-iodine lavage and SSI/PJI after primary total hip arthroplasty

Introduction

Unresolved issue remains regarding which patient populations benefit from diluted povidone-iodine (PI) irrigation for preventing surgical-site infection (SSI)/periprosthetic joint infection (PJI) after primary total hip arthroplasty (THA). We aimed to clarify the clinical effect of diluted PI lavage on SSI/PJI incidence in risk-stratified patients undergoing primary THA.
