title: Haemophilus influenza infection complicating a total knee arthroplasty.
abstract: Haemophilus influenza is rarely a cause of septic arthritis in adults. It has not been reported as a cause of infection in total knee arthroplasties. Haemophilus influenza septic arthritis is a late stage, hematogenous infection. A 43-year-old woman with a history of rheumatoid arthritis was found to have Haemophilus influenza infection 3 years after the index total knee arthroplasty. The patient was treated with debridement and systemic antibiotics. At the 5-year followup, the patient was comfortable and free of clinical signs of infection. This approach was successful at eradicating infection and salvaging the total knee arthroplasty.
