Septic Arthritis

Introduction

Septic Arthritis refers to a bacterial infection of a joint.  Children may develop this spontaneously from a hematogenous (or blood borne) source.  Certain pediatric joints are prone to developing these infections because of the structure of its growth plates (with the hip and knee being most common).  It is difficult for the body to fight off an infection inside a joint, so once septic arthritis is suspected, urgent surgery is necessary to clean out the joint.
