Total Knee Replacement

  • The main indication for a total knee replacement (TKR) is pain caused by arthritis
  • Arthritis can be caused by “wear and tear”, an inflammatory condition or a previous injury
  • A TKR is performed when non-operative measures have not been effective
  • The operation is usually performed under a spinal anaesthetic
  • The procedure involves removal of the worn cartilage from the bones in the knee (femur and tibia). This is replaced with metal components and a specialized plastic spacer
  • Special precautions are taken to minimize the risks of infection and blood clots (DVT or deep vein thrombosis)
  • It is usual to stay in hospital for a few days to ensure good pain control and for rehabilitation (physiotherapy)
