title: Infection of a total knee joint prosthesis by peptostreptococcus micros and propionibacterium acnes in an elderly RA patient: implant salvage with longterm antibiotics and needle aspiration/irrigation.
abstract: We describe the favourable long-term outcome after late total knee joint prosthesis infection in an elderly RA patient. Peptostreptococcus micros and Propionibacterium acnes were cultured from the synovial fluid, and the finding of a coexistent abscess at the root of a wisdom tooth suggested a dental origin to the joint infection. Long-term antibiotics in conjunction with aspiration/irrigation resulted in salvage of the implant and an excellent functional outcome.
