Smith & Nephew recalled the cementless versions of the Profix II and Oxinium Genesis II knee implants. The company recalled these defective knee replacements voluntarily after they failed to bond properly. Some patients who received these implants required revision surgery. Patients who received the Profix II or Oxinium Genesis II knee replacements have a higher risk of re-infection and further joint and muscular damage.
Approximately 200,000 to 300,000 knee replacements occur annually in the United States. People undergo this procedure when medication and physical therapy fail to help the pain.
