If your knee is injured, through either trauma or arthritis, performing everyday activities such as walking, climbing stairs, and even lying down, may cause some pain. If you have tried and exhausted all conservative treatment options such as medications, walking aids and physical therapy, then you may need to consider knee replacement surgery.

This type of surgery is a safe and effective reconstructive procedure that will enable you to resume activities that you are no longer able to.  If you are looking to get back to your daily routine as quickly as possible, you may want to consider a knee replacement. Coffs Harbour residents can contact the team at Mid North Coast Hip & Knee Clinic today for more information.

What causes the need for a knee replacement?

A knee replacement, may be recommended if the knee joint is worn, damaged, or stiff, and prevents you from carrying out your typical daily activities. If you have any of the following, then a knee replacement surgery may be of benefit to you:

  • Osteoarthritis with severe pain and stiffness
  • Deformity of the knee joint and instability
  • Chronic rheumatoid arthritis and pain
  • Previous traumatic knee injury

The difference
between a partial
knee replacement
and a total knee replacement

The severity of your condition will determine whether you require a partial or total knee replacement:

Partial Knee Replacement

If your condition has been diagnosed early and the arthritic damage to your knee is not too severe, you may be eligible for a partial knee replacement. In this instance the disease has not progressed to all 3 compartments of the arthritic knee, allowing the surgeon to replace fewer parts.

Total Knee Replacement

If you are suffering from severe arthritic knee pain or chronic knee inflammation, it is likely you may need a total knee replacement. All 3 major compartments of the knee may need to be replaced. Knee replacement prostheses are most commonly made of metal alloys, usually, titanium or cobalt-chromium based. Some implants are made of ceramics or ceramic/metal mixtures.

What is a knee replacement made of and how is it fixed in place?

Total knee replacement prostheses are most commonly made of metal alloys, usually titanium or cobalt-chromium based. Some implants are made of ceramics or ceramic/metal mixtures. The spacer between the femoral and tibial component, and patella resurfacing component, is made of ultra-high molecular weight polyethylene. The components may be fixed to the femur and tibia with or without bone cement. Cement fixation, particularly on the tibial side of the joint, is known to have a reduced rate of revision.

How is total knee replacement surgery carried out?

Our team of experts will guide you through your surgery from your initial consultation, all the way through to your post-operative care:


During your consultation, we will discuss your medical history, inspect your knee and your X-rays and may take some blood tests. We will talk you through the procedure and give you the opportunity to ask any questions you may have.


A total knee replacement involves replacing the main joint surfaces at the end of your thigh bone (femur) and shin bone (tibia). It may also involve resurfacing the kneecap (patella) with a plastic dome. The main steps of a knee replacement are:

  1. Damaged cartilage and bone are removed to prepare the joint for replacement.
  2. Once removed, the cartilage and damaged bone are replaced with a prosthetic. These parts are used to recreate the surface of the joint and are either cemented or fixed in place.
  3. If the patella is damaged, the undersurface will be replaced with a plastic dome.
  4. A spacer is then inserted between the new components to allow for smooth gliding.


Whilst every patient has a different starting point prior to knee replacement, patients recover better when they are well informed and have undergone a period of physiotherapy with strength and conditioning prior to surgery. Patients are encouraged to walk almost immediately following surgery under the supervision of a physiotherapist. It takes approximately 2 weeks for the skin wound to be well healed and it may be wet after that.

Most knee replacement patients will have returned to driving a car within 6 weeks. There will be a steady improvement over the first 3 to 4 months but it’s not unusual to still require some simple pain relief during this time. The knee replacement may remain swollen and warmer than the other side for up to 12 months after surgery but this is normal. Overall recovery for a total knee replacement can be up to 18 months.

Benefits of knee replacement surgery

There are a number of significant benefits of having knee replacement surgery:

  • Relieve pain
  • Correct leg deformity
  • Restore knee movement
  • Improved mobility
  • Resume your regular everyday activities

Severe inflammatory disorders are one of
the main causes of having a knee replacement.

Are there any risks associated with a knee replacement?

Any surgical procedure carries risks, but when carried out by a highly experienced professional like Dr Broadhead, it’s considered a safe and effective procedure. Unlikely risks associated with a knee replacement include:

How much does a knee replacement cost?

The cost of knee replacement in Australia varies widely, depending on whether treatment occurs in a public or private hospital and the level of cover provided by private health insurance. Treatment at a public hospital is fully covered by Medicare. For treatment at a private hospital, our staff will be able to provide you with a quotation, taking into account your level of health insurance coverage.

If you do not have private health insurance but still wish to be treated in a private hospital, you will be provided with a full fee estimate, including fees for the surgeon, surgical assistant, anaesthetist, the private hospital and any required surgical implants or prostheses.

If you’ve had previous knee surgery, it won’t stop you from having a knee replacement. However, the choice of prosthesis used by your surgeon may vary.

Here are several tips to help you ready your home for your recovery:

  • Clean and remove all clutter and tripping hazards
  • Install fall-prevention equipment
  • Prepare a rehabilitation and physio area
  • Sleep downstairs until you can walk upstairs comfortably

On average the knee implants used for a knee replacement last about 15 to 20 years. However, age is a major factor in determining how long a total knee replacement will last. Males also have a higher rate of revision than females.

Most knee replacement patients are between 50 to 70 years. However, patients over the age of 70 can also benefit from the procedure.

A knee replacement is a major operation and is only recommended if other treatment options haven’t helped to relieve pain or improve mobility.

As the surgery is carried out using anaesthesia, you won’t feel any pain during the operation. However as with any surgery, after the procedure, you’ll feel some discomfort but this is normal.
