… a 61-year-old woman had a total knee replacement. She went to her dentist’s office the following year for a teeth cleaning. According to the American Dental Association, patients with total joint replacements should be premedicated with antibiotics during the first two years. Although the dentist was aware of the knee replacement, he failed to premedicate her with antibiotics. After the cleaning, an infection set into her artificial knee causing its removal. She was without a knee for several months until she could have a second knee replacement. The dentist’s insurance company eventually settled with the woman after several depositions were taken.
