MRSA infection of a Primary TKA following an infected IV cannula site complicated by Stevens-Johnson Syndrome- A Case Report
We present here a 63-year-old lady who had a primary total knee arthroplasty (TKA) for osteoarthritis of knee. She developed methicillin resistant staphylococcus aureus (MRSA) infection of the primary prosthesis following an intravenous (IV) cannula site infection with MRSA bacteremia. This was complicated by Stevens-Johnson syndrome following vancomycin therapy for the infection, which was confirmed by clinical features including typical skin rashes and skin biopsy. She was treated with alternative antibiotics and was referred to a specialist orthopaedic unit where she had a two- stage revision. In retrospect, the infection could have been avoided if the IV cannula was not left in for so long. She also unfortunately had an adverse reaction to the vancomycin which complicated the situation, making management difficult. A team consisting of orthopaedic surgeons, microbiologists, dermatologists and physiotherapists was essential for successful management of this difficult and complicated situation.
