Robotic knee surgery may offer a precise and individualised approach to joint replacement, but a smooth recovery starts well before the day of the procedure. This robotic knee surgery preparation involves getting your body and mind ready well before the procedure, helping improve your hospital experience, reduce surgical risks, and help you feel more in control of the journey ahead.
This guide walks you through key steps to take in the weeks prior, including medical appointments, lifestyle adjustments, and emotional preparation. While each person’s situation is unique, the checklist below provides a general overview of what you can expect during the preoperative phase. Always follow the advice of your knee orthopaedic surgeon and care team.
Medical Tests and Appointments: What You’ll Likely Need
In the lead-up to robotic knee replacement surgery, your healthcare team will organise a series of medical assessments to ensure you’re fit for the procedure and to help plan your care.
Pre-surgical investigations
Most patients will undergo a combination of the following tests:
- Blood tests: These assess your haemoglobin, white cell count, kidney function, and blood clotting profile. Abnormalities may need to be managed before surgery.
- Electrocardiogram (ECG): Particularly important for patients over 60 or with a history of heart disease, an ECG checks your heart rhythm and looks for any underlying issues.
- Imaging: While imaging such as X-rays, CT scans, or MRIs may already be done during the diagnostic stage, your surgical team may request updated images to support robotic planning and navigation.
These investigations aren’t just routine. They form the foundation of your surgical safety plan. Your surgeon will use the imaging data to create a precise, computer-assisted surgical map tailored to your anatomy. Blood results help the team anticipate how your body might respond to anaesthesia and identify any hidden risks, such as anaemia or clotting concerns.
If any unexpected findings arise, your surgery may be rescheduled to allow time for further treatment or stabilisation. Following through on testing instructions (such as fasting or pausing supplements) ensures results are as accurate as possible.
Key Consults: GP and Anaesthetist Appointments
GP preoperative clearance
Your general practitioner may be asked to conduct a preoperative medical assessment and provide a clearance letter. This step is important for patients with multiple health conditions, or those taking long-term medications. Your GP may also support lifestyle preparation, including smoking cessation, managing blood glucose levels, and reinforcing healthy habits in the lead-up to surgery.
GPs play an important coordinating role, particularly if you see other specialists such as a cardiologist, endocrinologist, or respiratory physician. They can streamline communication between providers and flag issues early. This is also an ideal time to review and update your My Health Record, advance care directive, and emergency contacts, especially if you haven’t had surgery in some time. Your GP can also check your vaccination status (including influenza and COVID-19 boosters), which may reduce the risk of post-operative infection or complications.
As part of this preparation, it can also be helpful to understand robotic knee surgery costs and access in Australia. Knowing how technology, hospital setting, and insurance coverage interact within the healthcare system may help you plan your surgery timeline and discussions with your care team.
Anaesthetist consultation
Meeting with the anaesthetist is a standard step in preparing for robotic-assisted knee surgery. During this appointment, they’ll review your medical history, discuss the type of anaesthesia planned, and explain any associated risks. They may also provide fasting instructions, guidance on which medications to take (or withhold) on the day, and outline how post-operative pain will be managed.
Be prepared to discuss past experiences with anaesthesia, including any nausea, allergic reactions, or difficulties waking. If you have been diagnosed with sleep apnoea, use a CPAP machine, or use oxygen at home, these must be declared. Your anaesthetist may adjust your plan accordingly. They may also assess your airway and neck mobility, especially if there’s a possibility of difficult intubation.
For some patients, particularly those with heart or lung disease, additional pre-anaesthetic testing (such as a chest X-ray or lung function test) may be required. Understanding these factors in advance helps reduce complications during surgery.
Lifestyle Modifications to Support Surgery
Taking active steps to improve your health in the weeks before surgery can help reduce the risk of complications and support your recovery.
Smoking cessation
Quitting smoking is strongly recommended. Smoking increases the risk of slow wound healing, infections, and breathing problems during and after anaesthesia. Ideally, cessation should occur at least 6–8 weeks before surgery to allow your body time to adjust. Your GP or pharmacist can offer nicotine replacement therapies or a referral to Quitline services.
Stopping smoking also improves circulation and oxygen delivery to healing tissues, which is particularly important in the first few weeks after surgery. If quitting entirely feels overwhelming, reducing your intake is still a positive step. Many hospitals also offer inpatient nicotine patches during your stay to support comfort. Be honest with your care team about your smoking history, as it allows them to tailor care and monitor for known risks like chest infections or blood pressure changes under anaesthetic.
Weight management
If you live with obesity or carry significant extra weight, your surgeon may discuss targeted weight loss goals before proceeding with surgery. Even a modest reduction can decrease joint stress and lower anaesthetic risks. A dietitian or physiologist may be able to support this process.
Weight loss prior to surgery is not about appearance. It’s about function, safety, and recovery potential. Reducing central body fat, in particular, may lower the risk of pressure injuries and surgical site infections. It can also improve your body’s ability to mobilise after surgery, easing the transition to physiotherapy. However, any weight loss effort should be gradual and medically supervised. Crash diets or rapid fluid loss can weaken your immune system or impact medication absorption, which may delay recovery.
This makes managing weight before knee surgery a valuable part of preoperative planning, as it may help reduce surgical risks and support post-operative recovery in suitable candidates.
Prehabilitation (prehab)
“Prehab” refers to physical preparation before surgery. A physiotherapist may provide you with a tailored program to improve knee strength, flexibility, and mobility. While this doesn’t reverse joint damage, it may help you enter surgery in better condition, preserve muscle tone, and ease your transition to post-operative rehabilitation.
Prehabilitation for knee surgery may involve gentle strength exercises for the quadriceps and hamstrings, gentle stretches, and low-impact cardio activities such as stationary cycling or hydrotherapy. If mobility is limited, even small activities like ankle pumps or sit-to-stand drills can help maintain circulation. Strengthening your upper body may also assist with using mobility aids, such as crutches or walkers, after surgery. Starting a program early allows you to build consistency and confidence, and gives your physiotherapist time to adapt exercises around any flare-ups or pain.
Alcohol reduction
Limiting or avoiding alcohol in the weeks before surgery can reduce the risk of bleeding, liver-related complications, and interactions with anaesthetic drugs. Chronic alcohol use may also impair the immune system and delay wound healing. Your anaesthetist or GP may ask about your typical intake, and suggest a reduction plan if needed. If you’re drinking more than 2–3 standard drinks per day, it’s worth discussing strategies to taper safely.
Improving sleep and stress management
Poor sleep in the lead-up to surgery can affect your immune system, mood, and pain threshold. Establishing a sleep routine, such as winding down earlier, limiting screens at night, or cutting back on caffeine, can help your body prepare for healing. Similarly, managing stress through breathing exercises, gentle movement, or counselling support may help reduce pre-surgery anxiety and improve overall resilience.
Nutritional support and protein intake
While weight loss may be a goal for some, it’s also important to nourish your body in preparation for tissue healing. Eating a balanced diet rich in protein (like lean meats, dairy, legumes, or tofu), iron, and vitamins (especially vitamin C and D) can help prepare your immune system and support muscle recovery post-surgery. If you have dietary restrictions, a referral to a dietitian can help ensure you’re getting the nutrients you need without compromising your health.
Screening for Infections and COVID-19
Infections can delay or cancel surgery, so your team will likely conduct screening before your admission.
Nasal or skin swabs
Some hospitals routinely test for Staphylococcus aureus colonisation (including MRSA) using a nasal swab. If positive, you may be prescribed topical treatments or antibiotics to reduce the risk of surgical site infection.
These organisms often live harmlessly on the skin or in the nose, but can become problematic when surgery is involved. Treatment usually involves a five-day course of nasal ointment and antiseptic body wash, which you’ll be asked to use before hospital admission. If you have a history of resistant infections, previous wound complications, or work in a high-risk environment (such as aged care), let your team know. This may influence your screening or treatment plan.
COVID-19 testing
Depending on your hospital’s policy and current public health guidelines, you may be asked to undergo a rapid antigen test (RAT) or PCR test in the days before surgery. If you start feeling unwell with symptoms like a fever, cough, or shortness of breath, notify your healthcare team promptly, as surgery may need to be postponed for safety.
In some hospitals, you may also be asked to limit social contact in the 3–5 days prior to surgery to reduce exposure. This might include avoiding large indoor gatherings, using a mask in public spaces, or arranging home delivery for groceries.
If someone in your household has recently had a positive COVID-19 result, inform the hospital as soon as possible. They may provide further instructions or postpone the procedure. Keeping lines of communication open helps protect you, the care team, and other patients.
Dental clearance (for some patients)
If you have poor dental health or untreated gum disease, your team may recommend a dental check before surgery. That’s because bacteria from the mouth can enter the bloodstream and increase the risk of joint infection after implant surgery. This is particularly important if you’ve had past infections or a history of joint complications. If dental work is needed, it should be completed well in advance, usually a few weeks before the procedure.
Urinary tract infection (UTI) screening
If you’ve had frequent UTIs or symptoms like burning, urgency, or cloudy urine in the weeks leading up to surgery, your GP or surgeon might request a urine test. Undetected UTIs can increase the risk of post-operative complications, especially in older patients. For men with enlarged prostate symptoms or women with prior catheter use, this might be checked proactively.
What to Pack for Hospital
Most patients stay in the hospital for a few days after robotic knee surgery. Following a hospital checklist for knee replacement can help you feel more prepared and supported during your stay.
Suggested items:
- Comfortable, loose-fitting clothes (e.g. T-shirts, shorts, or tracksuit pants)
- Non-slip, supportive shoes or slippers
- Toiletries: toothbrush, toothpaste, soap, deodorant, moisturiser
- Any mobility aids you currently use (e.g. walking stick, brace)
- Bring a complete list of your regular medications, including names and dosages
- Medicare and private health insurance details
- Your phone, charger, and a small notebook or pen if you’d like to track information or reminders
Avoid bringing:
- Valuables or large amounts of cash
- Scented products (some hospitals request fragrance-free items)
Additional helpful items include lip balm, earplugs, or an eye mask for better rest, especially in shared rooms. If you wear glasses, hearing aids, or dentures, bring their cases and label them clearly. Consider packing clothes that are easy to put on over a swollen knee, such as shorts or wide-legged pants. If you’re unsure what to pack, call your hospital or surgical coordinator. They often provide a personalised list depending on your length of stay and mobility needs.
Preparing Mentally and Emotionally
While physical readiness is essential, preparing your emotional readiness for knee surgery can also make a big difference to how you experience surgery and recovery.
Managing pre-surgery anxiety
Feeling nervous is completely normal. If you’re feeling particularly anxious or have had mental health challenges in the past, it’s a good idea to speak with your GP or clinical team ahead of time. They may suggest practical strategies, refer you to a psychologist, or offer short-term support options to help manage distress.
Hospital social workers or perioperative nurses can also offer emotional support, especially if you’re feeling overwhelmed by the process. Some people find it helpful to attend hospital tours, information sessions, or pre-admission clinics to feel more familiar with the setting. Writing down your concerns and questions before your appointments can ensure you get the information you need. You might also ask your surgeon or physiotherapist about what to expect in the first 48 hours after surgery, so you’re not caught off guard.
Setting realistic expectations
Robotic knee surgery is a major procedure that requires planning, patience, and commitment to rehabilitation afterwards. While it’s natural to hope for a positive outcome, every patient’s recovery timeline is different. Preparing for gradual progress, potential setbacks, and changes to your daily routine can help you approach the experience with more resilience and flexibility.
Discussing expectations with your care team can also help clarify what’s typical versus what might need medical attention. Understanding that some discomfort, swelling, or temporary fatigue is normal can reduce anxiety later. You might also consider journaling your progress before and after surgery. It can help you reflect on small wins and give your team helpful insights during follow-ups.
Assembling your support network
Speak with family or friends about your upcoming surgery so you have help organised in advance. Support may include transport to the hospital, someone to take care of meals or pets, or just a friendly check-in while you’re adjusting. If you live alone, your care team may recommend short-term in-home support services.
Let your support person know about the hospital’s visiting policy, parking arrangements, and who to contact in case of updates. It’s also wise to nominate a primary point of contact who can relay information to others, which can reduce stress during your stay. If no personal support is available, discuss options early. Your hospital may have links to community services, transitional care programs, or rehabilitation facilities that can assist during the early days at home.
Clarifying your personal goals for surgery
While your surgeon’s clinical goals focus on joint alignment and mobility, it can be helpful to define your personal goals, such as being able to walk unassisted, play with your grandchildren, or return to gardening. Writing these down can keep you focused and motivated during the recovery journey. It also helps shift your mindset from “I’m having surgery” to “I’m preparing for my life after surgery.” Just keep expectations flexible. Progress takes time, and your team will help guide the next steps.
Planning for the temporary loss of independence
Even if you’re emotionally prepared, it can still feel confronting to need help with basic tasks like dressing or showering. Acknowledging this ahead of time, and viewing it as temporary rather than permanent, can reduce frustration. Discuss with your support team how you’d like to be assisted, whether that’s hands-on help, check-in messages, or quiet encouragement. Feeling in control of how you receive support can make a big difference.
Creating a pre-surgery routine or ritual
Some people find it helpful to establish a simple daily routine in the week leading up to surgery, something calming and purposeful, such as journaling, listening to a playlist, or taking a short morning walk. It signals to your brain that you’re preparing for something important, and gives structure to the wait. You might even pack a small keepsake or calming object (like a photo or affirmation card) in your hospital bag as a quiet source of comfort.
Final Reminders Before Admission
Here’s a quick recap of key steps to check off before surgery:
✅ Complete all requested bloods, scans, and ECGs
✅ Review your medications with your GP or pharmacist
✅ Finalise your GP and anaesthetist clearances
✅ Prepare your hospital bag early
✅ Follow infection screening instructions
✅ Organise transport and post-surgery support
✅ Prioritise rest and healthy routines in the final days
Try to keep your final 48 hours low-stress. Limit heavy lifting, ensure your home is ready for your return, and avoid alcohol or last-minute travel. Getting quality sleep and staying well hydrated can also support your body ahead of surgery. If you feel unwell or uncertain before your robotic knee procedure, contact your GP or surgical coordinator promptly.
Once your pre-surgery checklist is complete, it may also help to know what to expect on the day of robotic knee surgery. Understanding how admission, anaesthesia, and recovery are managed can give you a clearer picture of the hospital process and help you feel more confident as the procedure approaches.
Preparing for robotic knee surgery isn’t about having everything perfectly under control. It’s about giving yourself the time, support, and information you need to feel confident and ready. By preparing for knee surgery in advance, you can walk into the hospital feeling informed, empowered, and well-prepared for recovery.
