ZDF, a German public-service television broadcaster, has aired a report "Infected Artificial Joints" in its show "Volle Kanne" (in German).
Due to the aging population and the claim to be mobile even in old age, the number of joint replacement surgeries has been increasing steadily for years. When installing an artificial joint, however, bacteria can enter the body.
Surgeons estimate that around 24.000 artificial hip joints and 16.000 artificial knee joints require surgeons to operate or replace annually. For the affected patients then usually begins a long ordeal, because only a few clinics and doctors are prepared for such a complication.
ZDF Report "Infected Artificial Joints" (in German) is available here (available till January 15, 2019).
