Facing knee replacement surgery can feel daunting, but the right preparation can make all the difference. Whether it’s due to arthritis, injury, or years of wear and tear, this life-changing procedure is your first step toward less pain and more freedom.
In this guide, we’ll break down exactly what you need to know before surgery day, from prepping your body and home to managing expectations and recovery tips.
Step 1: Understanding Knee Replacement Surgery and what to expect
Knee replacement surgery is a common procedure designed to relieve pain and restore function in severely damaged knee joints. There are two main types: partial and total knee replacement. A partial replacement targets only the damaged section of the knee, preserving more of the natural joint and often allowing for a quicker recovery. A total knee replacement, on the other hand, involves replacing the entire joint with artificial components and is typically recommended when damage is widespread.
The surgery itself usually takes one to two hours and is performed under general or spinal anaesthesia. During the procedure, the surgeon removes damaged cartilage and bone, then fits the joint with metal and plastic implants that mimic the knee’s natural movement.
Recovery timelines vary: patients undergoing partial replacements may resume light activities within a few weeks, while those with total replacements often need several months of rehabilitation to regain full strength and mobility.
Setting realistic expectations is crucial. Recovery isn’t instant; it’s a gradual process that requires patience, commitment, and consistent physiotherapy. Swelling, stiffness, and fatigue are normal in the early stages, but with the right mindset and support, most people regain independence and enjoy a significant improvement in quality of life.
Step 2: Optimise Your Health Before Knee Replacement Surgery
Good overall health is one of the most important factors in ensuring a smooth surgery and a strong recovery. Taking time to prepare your body can reduce the risk of complications and help you heal faster. This means addressing any existing health issues and making positive lifestyle changes in the weeks or months leading up to your operation.
To give yourself the best chance of success:
- Manage chronic conditions like diabetes or high blood pressure with the help of your GP.
- Eat a balanced, nutritious diet rich in protein, vitamins, and minerals to support healing.
- Stop smoking to help improve circulation and wound healing.
- Reduce alcohol intake to support your immune system and liver function.
- Aim for a healthy weight, if possible, to reduce pressure on your new joint and lower surgical risks.
You might also consider rehabilitation, a tailored exercise programme led by a physiotherapist. Strengthening the muscles around your knee before surgery can improve mobility, reduce pain, and make post-op rehab more effective.
Step 3: Prepare Your Home for a Safe Recovery
Recovering from knee replacement surgery is much easier when your home is set up to support your healing. In the first few weeks, mobility may be limited, and everyday tasks can feel more challenging. Making a few simple adjustments before surgery can help you stay safe, reduce stress, and focus on your recovery.
To create a recovery-friendly environment:
- Remove trip hazards like loose rugs, clutter, or trailing cables.
- Set up a sleeping space on the ground floor if stairs will be difficult to manage.
- Install assistive devices such as grab rails in the bathroom, a raised toilet seat, or a walker for extra stability.
- Stock up on essentials. Fill your freezer with ready meals, and make sure you have enough groceries, toiletries, and medications to last at least a couple of weeks.
It’s also a good idea to organise help with daily tasks. Whether it’s a partner, family member, friend, or neighbour, having someone available to assist with cooking, cleaning, or errands can make a big difference in those early days. Planning ahead means you can focus on healing without worrying about the little things.
Step 4: Plan Ahead for Time Off and Support
Planning ahead for your time off and support network is just as important as preparing your body and home. After knee replacement surgery, your mobility will be limited, especially in the first few weeks, so it’s essential to give yourself enough time to rest and recover.
Most people need between six to twelve weeks off work, depending on the type of surgery and the physical demands of their job. To make the transition smoother:
- Arrange transport to and from the hospital, as you won’t be able to drive for several weeks after a total knee replacement
- Identify a recovery support ‘buddy’ who can help with errands, meals, and emotional support during the early stages.
- Plan for reduced independence in the first few weeks, especially when it comes to tasks like shopping, cooking, or getting to appointments.
Recovery is different for everyone, but most people start walking with aids within a few days, gradually building strength and confidence over several weeks. While some milestones, like driving or returning to work, have general timelines, it’s important to listen to your body and follow your healthcare team’s advice. Healing isn’t a race, and giving yourself the time and support you need will lead to better long-term results.
Step 5 : Prepare Mentally & Emotionally
Facing knee replacement surgery can stir up a mix of emotions: nervousness, uncertainty, and even fear. It’s completely normal to feel overwhelmed, especially when you're anticipating pain, time off work, or a long recovery.
Acknowledging these feelings is the first step toward managing them. Mental and emotional preparation is just as important as physical readiness, and it can make a big difference in how you experience the journey.
If you’re feeling anxious, there are several ways to find support:
- Mindfulness techniques like deep breathing, meditation, or gentle yoga can help calm your mind and reduce stress.
- Talking to a counsellor can provide a safe space to explore your concerns and build coping strategies.
- Joining a support group, either in person or online, can connect you with others who’ve been through the same experience and offer reassurance and practical advice.
Step 6: Follow Pre-Op Instructions Carefully
In the final days before your knee replacement surgery, it’s essential to follow all pre-operative instructions provided by your hospital or surgical team. These guidelines are designed to reduce the risk of complications and ensure everything goes smoothly on the day of your operation. Even small steps, like adjusting medications, can have a big impact on your safety and recovery.
Be sure to:
- Review your medications with your healthcare provider. Some may need to be paused or adjusted before surgery.
- Follow fasting instructions carefully, usually meaning no food or drink for a set number of hours before your procedure.
- Use any pre-op kits provided, such as antibacterial soap or wipes, to reduce the risk of infection.
It’s also important to let your surgical team know if you feel unwell in the days leading up to your operation. Even mild symptoms like a cough, cold, or fever could delay your surgery to protect your health. Being honest and proactive helps ensure the best possible outcome.
