KNEE REPLACEMENT SURGERY
Knee joint replacement surgery may be total where both sides of the knee joint are replaced, or uni-compartmental where only one side of the knee joint is replaced. The procedure is performed by separating muscles and ligaments around the knee to expose the knee capsule, and then the inside of the joint.
 
Knee replacement is surgery for people with severe knee damage. Knee replacement can relieve pain and allow you to be more active. Your doctor may recommend it if you have knee pain and medicine and other treatments are not helping you anymore
 
Knee Joint Replacement Anaesthesia
Knee Joint Replacement surgery can be performed under either general or spinal anaesthesia. Modern anaesthesia is safe and effective, but it does have some risks. Rarely, side effects from an anaesthetic can be threatening. Ask your anaesthetist for more information. Give your anaesthetist a list of all the medications you are taking or have taken, and any allergies you may have
Your anaesthetist can provide you with more information about the anaesthesia best in your case.
 
 
Before Knee Joint Replacement Surgery

Your surgeon needs to know about your medical history, so it is important to disclose all your health problems and symptoms. Some health problems may interfere with surgery, anaesthesia, sedation and care after surgery. Tell your surgeon about:

  • Any allergy or bad reaction to medication, antibiotics, anaesthetic drugs or other medicines
  • Any allergy or bad reaction to surgical tapes or dressings
  • Your smoking history; smoking interferes with healing, so quit it at least 2 weeks before surgery
  • all medication you are taking including insulin, warfarin or other blood thinning agents such as aspirin
  • any health supplements especially aloe vera, gingko or arnica as they may lead to bleeding
  • prolonged bleeding disorder or excessive bruising when injured
  • previous problems with blood clots in the legs or lungs
  • gout
  • diabetes
  • recent illnesses, including recent infections
  • long-term illnesses and lung or heart conditions
  • keloid scars or poor healing of scars after surgery

For 10 days prior to surgery please do not take the following medications:

  • Anti-inflammatories such as Aspirin, Cartia, Brufen,Voltaren, Synflex, Naprosyn, Nurofen, Diclofenac acid
  • Any health supplements especially those containing aloe vera, gingko or arnica

For 5 days prior to surgery please do not take the following medications:

  • Warfarin needs to be stopped five days before surgery.
 
If required, paracetamol - based pain killers can be used. Continue to take your other medications unless your surgeon advises otherwise

Also, on the day of surgery, you need to fast ( nothing to eat, drink or smoke) for six hours before the operation. Your surgeon may give you additional instructions.

It is important not to have any infections at the time of surgery, including teeth problems, bladder or skin infections. We suggest that you have a dental check up within 6 months prior to surgery as it is important not to have any major dental work for 6 months after the surgery. Please let me know if you have any infections prior to surgery.
 
To assist diagnosis and plan the procedure, your surgeon may require X-Ray Examinations. If you have X-Ray Films of your hip, bring them to hospital with you.
