Whilst most knee replacements do perform very well and 90% of them are still functioning 20 years after insertion, some knee replacements fail prematurely. The reasons for premature failure can include infection, fracture, loosening or excessive wear.
Whatever the reason, a revision knee replacement is a major undertaking.
The surgery is more difficult than the primary replacement, requires special skill on the part of the Orthopaedic Surgeon and special ancillary support within the hospital environment.
The rehabilitation procedure is usually longer and more difficult. The outcome is usually less certain than the primary knee replacement surgery.
Whilst revision knee replacement is not to be sought after or revered, it is sometimes unavoidable. This is an issue that your Orthopaedic Surgeon will discuss with you very carefully.
