Synovial osteochondromatosis mimicking septic arthritis

Abstract

Synovial osteochondromatosis is an uncommon benign condition with rare malignant potential. We describe an unusual case of synovial osteochondromatosis in a very elderly lady, who presented with an acute painful swollen knee, mimicking septic arthritis. This required knee replacement for long-term symptom control.
