Post-surgical Pyoderma Gangrenosum after Total Knee Arthroplasty: A Rare Case Report and Literature Review

Abstract

Introduction: Pyoderma gangrenosum (PG) following a primary total knee arthroplasty (TKA) surgery is extremely rare, with very few cases reported in the literature. Case Report: We report our clinical experience of a 65-year-old female who developed PG following a primary TKA surgery. Corticosteroids and local wound care with vacuum-assisted closure dressing helped achieve rapid improvement in the wound condition. Conclusion: Post-surgical PG in TKA can be challenging with limited evidence for its definitive treatment. A high degree of suspicion and a multidisciplinary management approach will help in the timely diagnosis and optimization of treatment for this condition.
