DifferentialDiagnosisofmonoarticulararthritis

• SepticArthritis– GramPositivecocci– GramNegativeRods– Lymedisease– Tb/Fungal

• CrystalArthritis– Gout– Pseudogout

• Spondyloarthritis(e.g.Reactive Arthritis)

• Vasculitis• PalindromicRheumatism

• Trauma• Exacerbationof

Osteoarthritis

1-5%ofpatientswithcrystalarthritiswillalsohavesepticarthritisofthesamejoint(Papanicolas etal,JRheumatol 2012;ShahK,etal,JEmerg Med2007)

Summary

• In patients presenting with monoarticular arthritis, infection is the primary concern

• Recognize signs of acute gout • Gout can cause severe arthritis but can easily be

managed (although often it is not).• Acute calcium pyrophosphate disease (CPPD) is

a strong mimicker of septic arthritis in the elderly.
