Knee Replacement

Knee replacement or knee arthroplasty is a surgical procedure done to restore the normal functioning of the knee. The surgery is suggested to those who are suffering from severe knee damage and knee pain. Knee replacement is usually, recommended only if all the other treatments fail to achieve good results. As the knee is the weight bearing surface of the body, knee replacement surgery is considered important. As the name suggests, the knee is replaced during the surgery. Mainly, knee replacement surgery is of two types:

  • Partial knee replacement and
  • Total knee replacement

n partial knee replacement surgery, any one of the joints is replaced. Whereas in total replacement surgery, both the knee joint sides will be replaced.

There is no age limit to consider the surgery. Usually, surgery is suggested during the 60s and 80s in most of the cases.

he surgery is to be done very carefully. The patient will be given any sedative to make her/him comfortable throughout the procedure. The patient will be kept in a bent position to get complete exposure of the joint surface. An incision of 6 to 10 inches will be made in the area, through which the surgeon moves the knee cap aside and cuts away the damaged part. After that, an artificial joint is attached to the surface. The doctor closes the incision after testing and ensuring the functioning of the artificial joint. In most cases, the whole surgery takes around 2 hours to complete.


Knee replacement surgery does not require extra time for recovery. The patient will be able to resume to normal physical activities after a few days. Any surgery will have some complications and risks associated with it. The most possible risks of knee replacement surgery include:
