Knee Replacement
Knee replacement may be considered when advanced arthritis causes ongoing pain and disability despite appropriate non-operative care. The decision is individual and follows a careful assessment of expected benefits, risks and alternatives.
What knee replacement involves
Knee replacement resurfaces damaged parts of the joint with metal components separated by a specialised plastic bearing. The aim is to reduce arthritic pain and improve useful movement and function.
A total knee replacement treats the main joint surfaces. A partial knee replacement preserves unaffected areas and may suit selected patients whose arthritis is limited to one compartment.
A knee replacement pathway includes decision-making, preparation, surgery, rehabilitation and follow-up—not the procedure alone.
Preparation and recovery are part of the plan.

02 / What to know
Is it the right time?
Surgery is generally considered when pain, stiffness and restricted mobility are having a substantial effect on daily life and appropriate non-operative treatment no longer provides adequate relief.
Dr Fraser will consider your symptoms, examination, imaging, health, expectations and personal priorities. Choosing not to proceed immediately is also part of shared decision-making, and alternatives will be discussed.
How the hip is assessed
If surgery is planned, preparation may include a medical review, medication instructions, pre-admission testing and strategies to improve general health. Tell the team about all medicines, allergies, dental or skin infections and changes in your health.
Planning transport, home support and a safe recovery space before admission can make the early recovery period easier.
Hospital and rehabilitation
After surgery, the hospital team will manage pain, monitor the wound and help you begin moving safely. Walking aids are commonly used at first, and exercises are progressed with guidance from the physiotherapy team.
Hospital stay and recovery time vary. Your return to driving, work, sport and other activities should follow advice specific to your operation and progress.
When hip replacement may be considered
Complications are uncommon but can include infection, blood clots, stiffness, ongoing pain, wound problems, injury to nerves or blood vessels, and issues with the implant. Individual risks will be discussed before consent.
Knee replacement aims to improve pain and function, but it does not recreate a natural knee and results vary. Rehabilitation and follow-up are important parts of the treatment pathway.
Discuss your symptoms and treatment options.

Knee Replacement FAQs
Helpful starting points before your consultation. Advice and recovery plans are always tailored to the individual.
What is the difference between partial and total knee replacement?
A partial replacement treats only the affected compartment of the knee, while a total replacement resurfaces the main joint surfaces. Suitability depends on the location and extent of arthritis, knee stability and other individual factors.
When might knee replacement be considered?
It may be considered for advanced arthritis causing substantial pain and disability when appropriate non-operative treatment has not provided adequate relief.
What should I expect during recovery?
Recovery is gradual and differs between patients. It commonly includes walking support and a rehabilitation or exercise program, with activity progressing under guidance from the treating team.
What should I bring to my appointment?
Please bring your referral, Medicare details, relevant X-rays or scans, a current medication list and any useful reports from previous treatment or surgery. Contact the practice before your visit if you are unsure what is required.
