Trauma-Induced Clostridium cadaveris Septic Arthritis of the Knee in an Immunocompetent Young Patient: A Case Report

Abstract

Objective:Rare disease Background:Clostridium cadaveris is a motile, anaerobic, gram-positive, spore-forming bacillus usually found in soil. However, rare cases of opportunistic infections have been documented in immunosuppressed individuals. This report details the case of an immunocompetent young patient who developed septic arthritis of the knee after a traumatic injury involving a rusty nail. The aim of this paper is to provide a comprehensive literature review, shed light on the potential occurrence of Clostridium cadaveris septic arthritis, and explore its management. Case Report:A young patient with no medical history presented a traumatic inoculation leading to septic arthritis on a native knee by Clostridium cadaveris. The patient underwent 2 surgical debridements after an initial bad evolution under probabilistic antibiotic therapy. Bacteriological long-growing cultures and antibiotic testing were employed to guide antibiotic therapy selection. The patient had a favorable clinical outcome with no residual knee complications, with laboratory results showed good evolution. A review of the literature showed that Clostridium cadaveris septic arthritis in immunocompetent patients is very rare. The management and subsequent results emphasize the potential impact of the initial emergency room treatment on patient outcomes, especially concerning seemingly benign traumas. Conclusions:This case report highlights the necessity of rapid diagnosis of the cause of septic arthritis, particularly in children, to prevent joint and tissue damage, and the rare diagnosis of knee arthritis with Clostridium cadaveris. This report expands understanding of osteoarticular infections and enhances the need for rapid diagnosis and early treatment, when managing cases with atypical presentations.
