Total knee replacement can last about 20 years and provide them with good mobility and little to no pain. This is the case for about 85-90% of patients who have had total knee replacement surgery.
For the other 10-15%, complications can arise over time, leading to the need to make adjustments to the prosthesis. Such adjustments are called Revision total knee replacement.
Most total knee replacement patients won’t need revision surgery. For others, revision surgery may be necessary if they experience loosening of the current prosthesis, instability, malalignment, or sepsis.
The implanted prosthesis may simply need an adjustment. In extreme cases, the entire mechanism is removed and replaced.
