Abstract

Symptoms and signs of septic arthritis are an important medical emergency, with high morbidity and mortality. We review the changing epidemiology of septic arthritis of native joints in adults, encompassing the increasing frequency of the disorder and its evolving antibiotic resistance. We discuss various risk factors for development of septic arthritis and examine host factors (tumour necrosis factor alpha, interleukins 1 and 10) and bacterial proteins, toxins, and enzymes reported to be important determinants of pathogenesis in mouse models. Diagnosis of disease is largely clinical, guided by investigations and the opinion of skilled clinicians. We emphasise the need for timely medical and surgical intervention-most importantly, through diagnostic aspiration of relevant joints, choice of suitable antibiotic, and appropriate supportive measures. Management is growing in complexity with the advent of novel and antibiotic-resistant causative microorganisms and within the current climate of increased immunosuppression. Findings from animal models and patients are shedding light on disease pathogenesis and the possibility of novel adjunctive treatments, including systemic corticosteroids, cytokines and anticytokines, and bisphosphonates.
