Perioperative Testing for Persistent Sepsis following Resection Arthroplasty of the Hip for Periprosthetic Infection

Despite the widespread use of a 2-stage exchange protocol for treatment of an infected total hip arthroplasty (THA), there is a paucity of information available to assist the surgeon in the identification of persistent infection prior to proposed reimplantation. The purpose of this study was to evaluate the use of the erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), synovial fluid white blood (WBC) count and differential prior to prosthetic reimplantation to identify persistent infection.
