Overview
Septic arthritis is a very much important consideration in adults presenting with acute monoarticular arthritis.
Defintion
Historical perspective
Pathophysiology
Hematogenous spread: Septic arthritis most commonly develop as a result of hematogenous spreading bacteria into the vascular synovial membrane.[1]
Direct inoculation: Direct inoculation of microorganisms may occur during joint surgery, particularly in association with knee and hip arthroplasties.
Contiguous spread: Bone infection can spread by breaking through its outer cortex and then into the intracapsular region that lead to joint infection. This kind of spread is more common in children as the small capillaries can cross the epiphyseal growth plate and permit extension of infection into the epiphysis and joint space.[2][3]
Risk Factors
Recent history of joint aspiration or local corticosteroid joint injection.[4][1]
