SUMMARY — THE REDUCTIONReview of pediatric knee septic arthritis: S. aureus predominates, diagnosis rests on exam, labs and arthrocentesis, empiric anti-staphylococcal antibiotics are standard, and debridement with lavage usually clears infection without further surgery.
Abstract, as published

» Septic arthritis of the knee is the most common type of septic arthritis in children, and it may result in irreversible joint damage. » Staphylococcus aureus is the most common pathogen associated with septic arthritis, but other causative pathogens are possible in children with certain risk factors. » The diagnosis of septic arthritis of the knee is based on history and physical examination, blood tests, and arthrocentesis. » Empiric treatment with anti-staphylococcal penicillin or a first-generation cephalosporin is usually recommended but may be tailored according to local resistance patterns and clinical culture data. » Open or arthroscopic surgical debridement including extensive lavage is effective in eradicating infection, and most patients do not require additional surgical intervention.
