Nocardia nova septic arthritis following total knee replacement: a case report.
We describe a case of Nocardia nova septic arthritis following a total knee replacement. A 55-year-old obese woman was admitted to hospital 5 months after knee surgery with a 3-week history of pain, swelling, and restricted mobility in her left knee but no preceding trauma/injury. 30 ml of cloudy joint fluid was aspirated and an arthroscopic examination showed extensive fibrin formation and synovitis. An arthroscopic washout was carried out using 16 litres of saline, followed by total synovectomy and intensive antibiotic therapy (clarithromycin 500 mg twice daily and co-trimoxazole [sulphamethoxazole 400 mg and trimethoprim 80 mg] once daily and augmentin duo forte 875 mg twice daily). At 2.5 years, the patient had recovered completely with no prosthetic loosening.
