A knee that dictates when you can walk, sleep, work or enjoy time with family can make the decision to have surgery feel both hopeful and daunting. Preparing for robotic knee replacement is not simply about packing a hospital bag. It is an opportunity to understand your care, strengthen your body where possible, organise the right support and make decisions with confidence.
Robotic-assisted knee replacement uses computer-guided technology to help your surgeon plan and carry out the procedure with a high degree of precision. The robot does not perform surgery independently. Your orthopaedic surgeon remains in control throughout, using the technology as an additional tool to support personalised planning, bone preparation and implant positioning.
The preparation process will differ between patients. Your age, general health, home environment, work demands, the severity of arthritis and the support available after surgery all matter. A careful plan should reflect your circumstances, not a generic checklist.
Understand what robotic knee replacement involves
A total knee replacement involves removing damaged joint surfaces and replacing them with carefully selected metal and high-grade plastic components. In robotic-assisted surgery, detailed imaging and computer planning may be used to build a three-dimensional map of your knee. During the operation, the system helps your surgeon work within the planned parameters while balancing the soft tissues around the joint.
For suitable patients, this technology may assist with accuracy and individualised implant positioning. However, it is not a substitute for sound surgical judgement, rehabilitation or realistic expectations. Not every patient needs robotic assistance, and not every knee problem requires a replacement. Your surgeon should explain why a particular approach is being recommended and discuss reasonable alternatives, including non-operative treatment where appropriate.
Useful questions for your consultation include what is causing your knee pain, whether a partial or total knee replacement is appropriate, what the expected recovery milestones are, and what risks apply in your situation. A transparent discussion is particularly valuable if you have had prior knee surgery, significant deformity, inflammatory arthritis or complex medical conditions.
Preparing for robotic knee replacement before admission
Your surgeon and hospital team will provide instructions tailored to your operation. Follow these closely, particularly where medications, fasting and admission times are concerned. If anything is unclear, ask early rather than making assumptions in the days before surgery.
Review your health and medications
A pre-operative assessment helps identify issues that could affect anaesthesia, healing or recovery. Depending on your health history, this may include blood tests, imaging, an ECG or review by an anaesthetist. Tell your care team about all prescription medicines, pharmacy products, vitamins and supplements, including herbal remedies.
Blood-thinning medication, diabetes medicines and some anti-inflammatory drugs may need to be adjusted before surgery. Never stop a prescribed medicine without specific advice from your surgeon, anaesthetist or usual doctor. Bring an accurate medication list to appointments and include any medication allergies or previous reactions to anaesthesia.
If you have dental pain, a skin infection, a wound, a urinary infection, fever or a new illness close to your surgery date, contact the practice or hospital promptly. Proceeding with an elective joint replacement while an infection is present may increase risk, and postponing surgery can occasionally be the safest decision.
Build strength without aggravating the knee
Better general conditioning can make the early stages of rehabilitation more manageable. A physiotherapist may prescribe exercises to improve thigh strength, knee movement, balance and walking confidence before surgery. This is often called prehabilitation.
The goal is not to push through severe pain. Gentle, consistent work is usually more useful than a sudden burst of strenuous exercise. Stationary cycling, pool-based exercise and targeted strengthening may be suitable for some people, while others will need a more cautious plan. If your knee swells or pain remains significantly worse after activity, discuss this with your physiotherapist or surgeon.
Nutrition also deserves attention. Aim for regular meals with sufficient protein, fibre and fluids, particularly if reduced mobility has affected your appetite or routine. If you have diabetes, maintaining good blood glucose control before and after surgery is a meaningful part of reducing complications and supporting wound healing. Smoking and vaping can impair healing and increase surgical risks, so stopping as early as possible is strongly encouraged. Your GP can help with a cessation plan.
Prepare your home for the first weeks
Most patients begin walking with a frame or crutches soon after surgery, guided by their physiotherapist. Before admission, make the route from your bedroom to the bathroom and kitchen as clear as possible. Remove loose mats, electrical cords and other trip hazards, and ensure there is adequate lighting for night-time trips to the bathroom.
Consider where you will sit, rest and manage everyday tasks. A stable chair with arms and a higher seat is often easier to use than a low, soft lounge. Keep commonly used items within reach and arrange a small supply of simple meals. If stairs are unavoidable, your hospital physiotherapist will usually practise safe stair technique with you before discharge.
You may benefit from equipment such as a raised toilet seat, shower chair or long-handled aids, but requirements vary. Ask your physiotherapist or occupational therapist for advice rather than purchasing equipment that may not suit your home or needs.
Plan for hospital discharge and recovery support
Knee replacement is a major operation, even when modern techniques and robotic technology are used. You will need practical support, especially during the first several days at home. Arrange for a responsible adult to take you home and, where possible, stay with you or check in regularly.
You may need help with meals, shopping, pets, laundry and transport. Plan this before surgery, particularly if you live alone or live in regional Victoria and need to travel for appointments. It is sensible to ask a family member or friend to attend a pre-operative appointment if you would value another person hearing the plan and taking notes.
Driving is not simply a question of time since surgery. You must be able to safely control the vehicle, perform an emergency stop, be off sedating pain medicines and meet insurer requirements. Your surgeon will advise when driving may be appropriate, but the timing differs depending on the operated leg, your recovery and the type of vehicle you drive.
If your work is physically demanding, discuss return-to-work expectations well before surgery. Desk-based duties may be possible sooner than roles involving prolonged standing, ladders, kneeling, heavy lifting or travel. A staged return or modified duties can be helpful, but should be based on function rather than a fixed date.
Know what recovery asks of you
Pain control, movement and wound care are all connected. Take medicines exactly as prescribed and discuss side effects such as nausea, constipation, dizziness or poor sleep. Do not wait until pain becomes overwhelming before raising concerns. Effective pain management supports participation in physiotherapy, but medication is only one part of recovery.
Swelling, bruising, stiffness and tiredness are common after knee replacement. Elevation, icing as advised, short regular walks and prescribed exercises can help. Recovery is rarely a straight line: one day may feel encouraging, while the next is harder because of swelling or fatigue. Progress is better judged across weeks, not hour by hour.
Your rehabilitation programme will focus on restoring knee movement, strength, walking pattern and confidence with daily activities. Attend appointments, complete the exercises you have been given and let your team know if pain is preventing you from progressing. Forcing the knee beyond what has been advised is not always beneficial, but avoiding movement because of understandable fear can also delay recovery. Your physiotherapist can help find the appropriate balance.
Contact your surgeon or hospital urgently if you develop increasing redness, warmth or discharge from the wound, a persistent fever, worsening calf pain or swelling, chest pain, sudden shortness of breath, or pain that is not controlled by your prescribed plan. These symptoms do not always indicate a serious complication, but they require timely assessment.
Bring your questions to the decision
The best preparation begins with an honest conversation. Ask about the surgeon’s experience with knee replacement and robotic technology, the expected hospital stay, the rehabilitation pathway, out-of-pocket costs and what support is available if questions arise after discharge. If you are considering surgery through a no-gap programme, confirm eligibility and understand what is and is not included.
Mr Viral Shah’s approach to joint replacement centres on evidence-based care, careful surgical planning and enough consultation time to discuss the details that matter to each patient. Technology can support precision, but dignity, clear communication and a shared understanding of the plan remain central to good care.
Give yourself permission to prepare steadily rather than perfectly. A safe home, a realistic support plan and a trusted surgical team can make the path from painful limitation to renewed movement feel far more manageable.
