INFECTION OF A TOTAL KNEE-JOINT PROSTHESIS BY PEPTOSTREPTOCOCCUS-MICROS AND PROPIONIBACTERIUM-ACNES IN AN ELDERLY RA PATIENT - IMPLANT SALVAGE WITH LONG-TERM ANTIBIOTICS AND NEEDLE ASPIRATION IRRIGATION/

We describe the favourable long-term outcome after late total knee joi nt prosthesis infection in an elderly RA patient. Peptostreptococcus m icros and Propionibacterium acnes were cultured from the synovial flui d, and the finding of a coexistent abscess at the root of a wisdom too th suggested a dental origin to the joint infection. Long-term antibio tics in conjunction with aspiration/irrigation resulted in salvage of the implant and an excellent functional outcome.
