Streptococcus gordonii prosthetic joint infection in the setting of vigorous dental flossing.
A 65-year-old woman with osteoarthritis, who underwent knee replacement 5 years prior, developed sudden onset knee pain and swelling. She had voluntarily starting a vigorous dental flossing regimen prior to the onset of symptoms. The patient underwent right knee arthrotomy, irrigation and debridement of right total knee arthroplasty and exchange of polyethylene with retention of the prosthesis. Intraoperative cultures grew Streptococcus gordonii. She was treated with 6 weeks of ceftriaxone and was later placed on oral antibiotic suppression.
