Rare Occurrence of Prosthetic Knee Septic Arthritis Due to Streptococcus Viridans in the Background of a Dental Procedure
The American Academy of Oral Medicine, American Dental Association (ADA), in conjunction with the American Academy of Orthopedic Surgeons (AAOS) and the British Society for Antimicrobial Chemotherapy, advises against the universal use of antimicrobial prophylaxis prior to dental procedures for the prevention of prosthetic joint infection (PJI). Here, we discuss the case of a patient with PJI in the background of periodontal scaling, which was done a week prior to presentation to the hospital. The PJI occurred with Streptococcus (S.) viridans, a rare organism for PJI but a common oral commensal. As the number of prosthetic joint surgeries are increasing and more data become available, prophylactic antibiotics might be considered to prevent PJI, especially in high-risk patients.
