Abstract
We describe a case of a 19-year-old male who presented to the South West Health Service with a septic knee, secondary to haematogenous spread from an iliacus abscess. Thus far, there have been no reported cases of haematogenous spread of infection from an iliacus abscess to an ACL reconstructed knee, let alone in a healthy young person with no risk factors. The patient has had several washouts of the knee along with the drainage of the abscess. The ACL graft was saved with the patient making a complete recovery.
Highlights
We describe a case of a 19-year-old male presenting with a septic knee, secondary to haematogenous spread from an iliacus abscess
Mr P. underwent ACL reconstruction with the use of an autologous hamstring graft, which has been found to have a lower infection rate compared to its synthetic counterparts
Addressing only the septic knee would have led to recurrent infections and incomplete resolution of the infection
Summary
We describe a case of a 19-year-old male presenting with a septic knee, secondary to haematogenous spread from an iliacus abscess. Mr P. first presented via his GP to Busselton Hospital (rural centre) complaining of feeling unwell He described an 8-day history of pain commencing in his lower back region and eventually involving the left knee. Microscopy on the aspirate showed large quantities of leukocytes and abundant growth of Staphylococcus aureus sensitive to flucloxacillin. His clinical picture worsened, and he was referred to orthopaedics at Bunbury Regional Hospital with rigors and spiking temperatures. Besides recent knee surgery (4 months after ACL reconstruction), Mr P. had no other risk factors for septic arthritis He is a social smoker and consumes fewer than 2 standard drinks of alcohol per week. A CT guided 14-French pig-tail catheter was placed via single pass into the left iliacus collection and
