Modern High Flexion Knee Replacement- Introduction
 

The following information about Modern High Flexion Knee Replacement will help you understand more about the surgery and might provide you with the solution to the symptoms you may have. If you still have questions, ask your doctor for more information.

Why would I need a knee replacement?
A Knee replacement is one solution for severe knee arthritis: when the gristle (articular cartilage) on the ends of the bones wears away exposing the underlying bone. The bones then rub directly against each other leading to pain and stiffness.

What is a Knee Replacement?
Knee replacement surgery recoats the bone ends, straightens the bowing of your leg and allows pain free movement.

 

Knee replacement surgery will:

  • Allow you to live your life without knee pain
  • Allow you to walk better and further
  • Improve your quality of life
  • Take away your night pain

Knee replacements have improved over the last 15 years, with the results now as good as hip replacements. There is however considerable variation between surgeons. Accuracy of surgical implantation is key to a good outcome as is meticulous technique to minimise complications.
Although it is called a knee replacement, it is more of a knee resurfacing with 9-11mm (about 3/8 inch) of the worn surface removed and a new surface or 'coating' applied.
The original knee replacements were large hinged components.
The operation involved putting in a new "working segment" and was a true knee replacement. Modern designs would be better termed knee resurfacing, preserving as much bone as possible and all bar one of the ligaments. However the old name "replacement" has stuck.
The operation takes between an hour and 1¼ hours.
