Patient Guide to Knee Replacement Recovery

Recovery is one of the first things that Adelaide patients want to understand when planning for knee replacement surgery, from their knee itself to how long they may need off work, when they can drive, how to manage stairs and how soon they can get back to activities.

Recovery takes time, but knowing what to expect in the first days, weeks and months can help you plan around work, home support and rehabilitation.

Dr David Kitchen, Adelaide Orthopaedic Specialist, provides total, partial, robotic-assisted and patient-specific knee replacement with treatment planning shaped around your knee anatomy, lifestyle and goals.

How long does knee replacement recovery take?

Knee replacement recovery is gradual. Most people are standing and walking short distances with support early after surgery. The first few weeks involve swelling control, pain management, wound care, gentle movement and physiotherapy.

Noticeable progress can happen across the first 6 to 12 weeks, but recovery continues for months. Full recovery may take up to 12 months, with progress shaped by your general health, fitness before surgery, the type of knee replacement, support at home and your rehabilitation program.

The following guide explains what you may experience at each stage. Your treating team will provide instructions based on your procedure and recovery.

Week 1 after knee replacement

The first few days are about getting you moving safely and preparing you to return home.

You will usually spend a short period in hospital, where the team will monitor your pain, wound and mobility. With support, you will begin walking using a frame or crutches, practising gentle exercises and learning how to manage everyday movements.

Once home, you may notice tiredness, swelling, bruising and discomfort. Simple tasks can feel slow and even going to the bathroom or preparing a meal may take more effort than usual. During this stage, the main goals are:

Taking medication as directed
Keeping the wound clean and dry
Elevating the leg to help manage swelling
Completing gentle exercises from your care team
Walking short, regular distances with your walking aid

Arrange help with meals, shopping, cleaning, transport and pets before surgery. Having support at home can make those first few days easier to manage.

Weeks 2 to 3: Getting back into a home routine

By weeks 2 to 3, home routines usually start to feel more manageable. You may still need a walking aid and regular rest. Swelling can also remain quite noticeable, especially later in the day.

Physiotherapy is an important part of your recovery. The goal at this stage is to keep the knee moving, support muscle activation and reduce stiffness. It can be frustrating when one day feels better than the next, but progress after knee replacement is not a straight line.

You will be working on bending and straightening your knee, improving your walking pattern and gentle strengthening exercises. Activities such as getting out of a chair or managing stairs may still require extra care. Also, sleep can still be interrupted, so plan your day around manageable periods of activity followed by rest.

Weeks 4 to 6: Building independence

Weeks 4 to 6 are often when patients start to feel more independent. You may be walking further, moving around the house more easily and needing less pain medication.

Swelling and stiffness can still come and go. A busy day, longer walk or extra time standing may leave the knee feeling tighter by evening, even when recovery is progressing.

Return to work varies. Desk-based work may be possible earlier than physically demanding work. Jobs that involve standing, driving, lifting or kneeling generally need a longer recovery plan.

Driving should only resume once you have medical clearance, are no longer taking medication that affects alertness and can safely control your vehicle in an emergency.

Your physiotherapist and the surgical team will guide you as you increase your activity.

Weeks 7 to 12: Returning to everyday activities

From weeks 7 to 12, recovery usually becomes less about basic movement and more about rebuilding strength, confidence and daily function.

You may start to increase your walking distance, add more strength work and return to light hobbies. A stationary bike, pool-based exercise or gym-based rehabilitation may be discussed once your wound has healed and your care team is happy with your progress.

This is also when people start testing the knee in real life. A trip to the shops, a longer lunch out, grandkids visiting or a return to work can show where more strength and stamina are still needed.

Your knee may still feel warm or swollen after activity. Keep following the advice from your physiotherapist and surgical team as you build activity.

Three to six months: Getting back to the things you enjoy

Between three and six months, the knee often feels more reliable in daily life. Walking, stairs and errands may feel easier, but higher-demand activities can still take time.

Goals at this stage can range from getting back to golf, longer walks, cycling, travel or more time outdoors to moving more steadily around the home and having fewer interruptions from knee pain.

It is still worth pacing yourself. Recovery is not only about the joint. Muscles, balance, confidence and general fitness all need time to rebuild.

Six to twelve months: Continuing to build strength

Recovery can continue throughout the first year after knee replacement.

Your knee may gradually feel more comfortable and reliable as your strength, movement and confidence improve.

You may find yourself thinking less about your knee and spending more time enjoying activities that had become difficult before surgery.

Keep following your treating team’s advice about rehabilitation and returning to more demanding activities.

When should you contact your medical team during recovery?

Swelling, bruising and discomfort are expected during the early stages of knee replacement recovery, but certain symptoms need medical attention.

Contact Dr Kitchen, GP or treating medical team if you experience increasing redness, wound discharge, fever, worsening pain or sudden calf swelling.

If you are concerned about your recovery or notice an unexpected change in your symptoms, contact your treating medical team – do not wait for your next scheduled appointment.

Knee replacement recovery FAQs

When can I walk after knee replacement?
Walking usually starts early after surgery with support from the hospital team. You will often use a frame, crutches or a stick during the first few weeks.

When can I drive after knee replacement?
Driving must wait until you have medical clearance, are off medication that affects alertness, and can move your leg well enough to control the car safely.

When can I return to work after knee replacement?
Return to work varies with your recovery and the type of work you do. Desk-based work may be possible sooner, but jobs involving prolonged standing, driving, lifting, kneeling or physical labour generally need more time.

Is swelling normal after knee replacement?
Yes. Swelling can last for several months. Rest, elevation, ice as directed and gentle movement can assist.
