Partial Knee Replacement

Osteoarthritis of the knee frequently affects only isolated areas of the knee. In these circumstances it may be possible to perform a partial rather than a total knee replacement. This is also known as unicompartmental knee replacement.


A partial knee replacement can be performed through a minimally invasive  operation which usually allows a much quicker recovery than total knee replacement. A partial knee replacement also allows the surgeon to preserve the natural ligaments of the knee. This allows excellent range of motion and leads to a more "normal" feeling knee for the patient. A disadvantage of partial knee replacement is that if the unreplaced parts of the knee develop arthritis, further surgery my be required to convert the partial to a total knee replacement. Although the risk of complications is lower than that of total knee replacement, problems may still occur.


A detailed explanation of the advantages and disadvantages of partial knee replacement can be seen by clicking on the partial knee replacement booklet link on this page.
