Why might I require a revision after knee replacement surgery?

The most common reason for failure is loosening of the artificial surface from bone. The cause of this loosening is complicated, but this is a known problem with artificial joints and loosening is not usually a failure of the surgeon doing it. Wearing of the plastic bearing may also result in the need for a new bearing. Newer plastics for the bearing surface have improved the longevity of knee replacements and represent an exciting improvement in these implants used during your knee replacement surgery.
