Functional outcome of two-stage reimplantation in patients with periprosthetic joint infection after primary total knee arthroplasty.

Introduction: Two-stage reimplantation in patients with chronic periprosthetic joint infection (PJI) after total knee arthroplasty (TKA) with the use of either articulating or static antibiotic-loaded spacers during the first step is considered to be the golden standard in orthopaedics.

The Aim Of The Study: The aim of the study was to evaluate the correlation of spacer type with the infection elimination rate as well as functional outcomes after two-staged revision TKA in patients with PJI.

Materials And Methods: The cohort comprised 161 patients who were treated for PJI after TKA during a period from January 2007 to December 2015.
