Septic arthritis is an infection of the joint space caused by bacteria, fungi, mycobacteria, and viruses. Septic arthritis typically involves large joints such as the knee, hip, and shoulder, though any joint can be affected. The knee is most commonly affected in adults, while the hip is most commonly affected in children. The bacteria responsible for septic arthritis vary by the age of the patient, though Staphylococcus aureus is a common pathogen across all age groups. Septic arthritis can lead to permanent joint damage unless treated expeditiously with joint irrigation and appropriate antibiotic treatment.Full Article - https://www.orthopaedia.com/septic-arthritis-2/
