Why have knee replacement surgery?

Knee joint replacement can improve a patient’s quality of life by reducing knee pain and increasing mobility. As a result, mental health can also improve after surgery as you are able to get back to doing your favourite activities and live with less pain.

Underlying causes for knee replacement include:

  • Osteoarthritis
  • Rheumatoid arthritis
  • Traumatic arthritis
  • Injury
  • Joint deterioration due to age
  • Joint deterioration caused by weight
  • Genetic predisposition or family history of joint deterioration
  • Gout
  • Death of the knee bones
  • It’s a big decision to have knee surgery. This means you may be a good candidate for surgery if non-surgical methods are not managing your pain.

    Non-surgical pain-management methods include:
  • Painkillers and anti-inflammatory medication
  • Steroid injections
  • Weight loss
  • Regular exercise
  • Use of a mobility aid or walker

How is knee replacement surgery performed?

Knee joint replacement generally takes from 1 to 2 hours to perform.During surgery, damaged bone and cartilage from your knee joint. They will then replace the damaged parts with an artificial joint also called a prosthesis.

Types of Knee Replacement Incisions

Your surgeon will make a vertical cut on your knee.

The size of this incision depends on the type of replacement you have.

A total knee joint replacement involves a vertical incision down the entire front of the knee.

Partial knee joint replacement usually requires a smaller vertical incision that is on the side of the knee joint that will be replaced.

Types of Knee Replacement Techniques

To replace the knee joint, the surgeon removes the damaged bone and cartilage from the knee after making the incision.

They shape the bottom of the thigh bone called the femur and the top of the shin bone called the tibia to fit the implant. This implant can replace the entire joint for a total knee replacement, or only half of the joint for a partial knee replacement.

Your surgeon will tell you what kind of knee joint replacement you will have well before the day of your surgery.

Total Knee Replacement

As seen below, a total knee joint replacement involves implants on the femur and tibia, as well as a cushioning plastic between the two.


The backside of the kneecap can sometimes also be resurfaced or be replaced with an implant.

Partial Knee Replacement

The procedure for partial knee joint replacement is nearly identical to that for total knee replacement. The only difference is that only half of the joint is replaced as seen in this diagram:


After placing the prosthesis, the surgeon will test the fit of the artificial joint by moving your leg. They may make some final adjustments at this point.

When they are happy that the artificial knee joint fits nicely, they secure the prosthetics into place. Sometimes they do this with the aid of a medical-grade bone adhesive.

Once they are happy with the alignment, they will close the incisions and the surgery will end.

You will stay in the hospital to recuperate from surgery for up to 5 nights depending on how quickly you recover.

Every surgery comes with possible risks and complications. To reduce your risk of any risks or complications forming, it is important that you follow the exact recommendations given to you by your surgeon.

Some risks apply to surgeries of all kinds. These include, but are not limited to:

  • Blood clot formation
  • Anaesthetic complications
  • Nausea and vomiting
  • Post-operative pain

Risks and complications specifically associated with knee joint replacement surgery include:

  • Fractures of the tibia or femur
  • Loosening of the artificial joint
  • Wearing out of the artificial joint
  • Damage to arteries, nerves, or ligaments surrounding the knee
  • Excessive bleeding
  • Bruising
  • Infection
