If you’re preparing for knee surgery, whether it’s a total knee replacement, partial replacement, ligament reconstruction, or arthroscopy, one of the most valuable steps you can take before the operation is prehabilitation. Prehabilitation means actively preparing your body and mind in the weeks before surgery so you can start recovery from a stronger foundation.
As a specialist knee surgeon in Sydney, Dr Jonathan Negus works with patients who choose prehabilitation to focus on three key areas: improving strength, building a positive mindset, and setting the stage for better recovery outcomes. Each plays a unique role in how smoothly the surgical journey unfolds.
This article will explore each area in detail, so you can see how they fit together, and why they’re best addressed individually under the guidance of your care team.
Boosting Strength Before Knee Surgery
Boosting strength before knee surgery is one of the most recognised parts of prehabilitation. Stronger muscles and joints can better support you in the immediate post-operative period.
Targeting key muscle groups
Before surgery, it’s important to focus on the muscle groups that stabilise and protect the knee. The quadriceps help straighten the leg, the hamstrings control bending and provide dynamic support, the gluteal muscles aid hip stability, and the calf muscles help with push-off when walking. Strength in the hip stabilisers also contributes to better leg alignment.
Functional strength-building exercises
Low-impact, targeted exercises can build this foundation without overloading the joint. Examples include sit-to-stand from a stable chair, wall slides, straight leg raises, step-ups onto a low platform, and calf raises. These are best introduced with a physiotherapist’s guidance so they’re tailored to your mobility and pain levels.
Enhancing joint mobility and flexibility
Even before surgery, maintaining a healthy range of motion can make post-operative movement less challenging. Gentle stretches for the hamstrings, quadriceps, calves, and hips help reduce stiffness. Mobility work should be done within a pain-free range to avoid irritation.
Core stability and balance work
While it might not seem directly connected to the knee, strong core muscles and good balance can make a big difference when walking with crutches or a walker. Exercises like gentle bridging, seated balance practice, and supported single-leg stance can help you maintain stability after surgery.
Cardiovascular conditioning without joint overload
Low-impact cardiovascular exercise, such as stationary cycling, pool walking, or gentle elliptical work, can improve circulation and endurance. Incorporating water-based activities, and even familiarising yourself with approaches like using water therapy for post-surgery recovery ahead of time, may help you plan for a smoother transition into rehabilitation. Good cardiovascular health supports your ability to tolerate surgery and begin early post-operative rehabilitation.
Boosting Mindset Before Knee Surgery
Boosting mindset before knee surgery is just as important as physical preparation. A confident, informed mindset can help you manage the lead-up to surgery and approach recovery with greater resilience.
Understanding the surgical journey
Knowing what will happen on surgery day, from admission through to discharge, can ease uncertainty. Your care team can walk you through each step, from anaesthetic preparation to initial physiotherapy sessions in hospital. Reviewing a robotic knee surgery checklist can also help you feel more organised and confident about the process, particularly if you’re having a technology-assisted procedure.
Managing pre-surgery anxiety
Many people feel some apprehension before surgery. Strategies like deep breathing, guided relaxation, or listening to calming audio can help lower stress levels. It’s also wise to limit exposure to unverified or alarming online information.
Building a supportive network
Having friends, family, or community contacts who can offer emotional reassurance before and after surgery can make the process less isolating. Even short daily check-ins can boost morale.
Developing recovery self-efficacy
Self-efficacy is the belief in your ability to follow through with your recovery plan. This can be built by setting small, achievable goals before surgery, such as completing your prescribed prehab routine each day.
Maintaining motivation in the lead-up
Consistent engagement with your preparation plan can be supported by tracking your exercises, keeping a simple progress log, or rewarding yourself with enjoyable non-physical activities once you’ve met your daily goals.
If your procedure involves robotic assistance, mentally preparing for robotic knee surgery can help you feel more comfortable with the technology, understand its role in your operation, and focus on the aspects of recovery you can directly influence.
A strong mindset can be just as important as physical strength in shaping your recovery journey. If you’d like to discuss your concerns and gain tailored advice, you can book a consultation with Dr Jonathan Negus.
How Prehabilitation Influences Recovery Outcomes
Prehabilitation for knee surgery’s ultimate value lies in how it sets the stage for a smoother, more confident recovery. But these outcomes are a result of the preparation work you’ve already done.
Faster functional milestones post-surgery
Patients who enter surgery with better baseline strength and mobility often reach early milestones, such as walking short distances, getting in and out of bed independently, or using stairs, more quickly.
Lower complication risks
Improved circulation and muscle conditioning may reduce the likelihood of stiffness or delayed wound healing. While no preparation can remove all risks, it can help support a more stable recovery environment.
Improved surgical tolerance
Good physical conditioning can assist your body in coping with the demands of anaesthesia and the initial physical stress of surgery. This may contribute to a smoother immediate post-operative phase.
Shorter hospital stays
Meeting discharge criteria, like walking safely with an aid and managing basic daily movements, may happen sooner for those who have completed a tailored prehabilitation program.
Better long-term return to activities
When you’ve built a foundation before surgery, the process of resuming your chosen activities, whether it’s gardening, golf, walking, or work tasks, can feel more achievable once your surgeon and physiotherapist clear you to do so.
Your Pathway To A Stronger Recovery
Prehabilitation before knee surgery works best when each area, including strength, mindset, and recovery outcomes, is addressed in its own right. Focusing on just one may help, but a balanced approach gives you the best preparation for the surgical journey ahead.

Frequently Asked Questions (FAQs)
1. How long before knee surgery should I start prehabilitation?
Most people benefit from starting 4–6 weeks before surgery, but even a shorter period can still help. The ideal timing depends on your current mobility, overall health, and the surgery date set by your surgeon.
2. Can prehabilitation be done at home, or do I need supervised sessions?
A combination works well. Many people start with a physiotherapist to learn the correct techniques, then continue the exercises at home. Supervision is particularly important at the start to avoid strain or unsafe movements.
3. Is prehabilitation suitable for older adults or people with other health conditions?
Yes, but the program should be adapted to your fitness level and any existing medical conditions. Your GP, surgeon, or physiotherapist can help ensure your plan is both safe and effective.
4. What if I have significant pain before surgery? Can I still do prehabilitation?
Prehabilitation can usually be modified to work within your comfort range. Low-impact, gentle exercises and mobility work can often be done without worsening pain. If you’re under the care of a knee specialist such as Dr Negus, they can guide your physiotherapist on what’s safe for your specific condition.
5. Will my hospital or surgeon provide a prehabilitation plan?
Some hospitals and surgeons offer structured prehab programs or can refer you to a trusted physiotherapist. In Sydney, Dr Negus works closely with allied health professionals to ensure patients have a tailored plan that matches their surgery type and recovery goals.
