[A prosthetic joint infection caused by Streptococcus pneumoniae: a case report and review of the literature].
We report a case of hematogenous streptococcus pneumoniae infection of a total knee arthroplasty observed in an 82-year-old woman who initially presented a lung infection. The therapeutic approach was largely dictated by the patient's precarious general status. Arthroscopic washings were associated with adapted antibiotics followed by removal of the prosthesis and replacement with a spacer. The patient declined further intervention so the prosthesis was not reimplanted. Hematogenous infections of joint prostheses are rarely caused by such streptococcal species. Since this is a well known germ, it would be logical to apply the usual rules for treatment of infected prostheses caused by sensitive germs. However, the analysis of the present case and a review of the literature shows that various therapeutic approaches have been used. These infections appear to be more common in seriously ill patients which could explain this variability. Mortality is high. The number of reported cases is too small to propose a specific treatment.
