The First Stage of Knee Revision Arthroplasty in Periprosthetic Infection with Replacement of a Large Defect Double Cementing Method: A Case Report

AIM: Large bone defects in patients with chronic deep periprosthetic knee infection is a major problem. It is widely accepted that bone defects filling with polymethylmethacrylate (PMMA) cement could be used only in selected cases of small bone defects (up to 5 mm) and less than 50% of articular surface due to multiple reasons: risk of thermal bone damage, inadequate cement pressurization and bone cement shrinkage, etc. Staged cementing for preventing bone heating and over negative effects of cementing on a thick layer of bone cement has limited support in the literature. CASE PRESENTATION: We present the case of 4.5 years follow up after temporary-permanent spacer implantation in a 63-year-old male with chronic deep knee PJI and tibial AORI type 3 bone defect reconstructed via double cementing method. RESULTS: Method of double (staged) cementing used for reconstruction of epiphyseal tibial bone defect in a patient with fistula form of knee PJI shows excellent clinical results at 4.5 years follow up.
