What does rehab after a knee replacement involve?
Rehab is the work of getting your new knee bending, straightening and carrying your weight, while the muscles around it grow strong again. It is mostly exercise, practised in short, regular sessions, with hands-on help from the physiotherapist.
Your surgeon’s instructions always come first. The physiotherapist works inside them: what movement is allowed, how much weight the leg can take, and what to avoid.
Who needs a knee replacement, and why is rehab part of it?
A knee replacement is suggested when wear and tear in the joint (osteoarthritis) is severe and other care has not been enough. The World Health Organization (WHO) lists joint replacement as management for severe joint damage [1]. If you are still deciding, our page on knee osteoarthritis explains what comes before surgery.
The operation changes the joint. It does not train the muscles, balance or walking habits you built up over years of a painful knee. That is the job of rehab, and it is why the weeks after surgery matter as much as the operation.
What will the physiotherapist check first?
We begin by reading your discharge papers and listening to how you are managing. Then we look at the knee and the whole leg.
- The wound and swelling, passed to your surgeon if anything looks wrong.
- How far the knee bends and straightens.
- Strength in the thigh, hip and calf.
- How you get out of bed, sit down, stand up and walk.
- Balance, and whether you use a walking frame or crutches safely.
- What you most want to do again, such as the kopitiam, the market or a short morning walk.
A clinical practice guideline for physical therapist management of total knee arthroplasty (knee replacement) exists, and was revised in 2026 [2]. We use guidance like this alongside your surgeon’s instructions, and timings are agreed one patient at a time.
What does a home visit add after surgery?
Most people go home before they feel ready. A home visit lets us fix problems where they happen, not in a clinic that looks nothing like your house.
In an Ipoh terrace house, that means the staircase to the bedroom, the bathroom step, the squat toilet and the low sofa. We practise the safe way to do each, and tell you early if a chair needs raising or a rug needs to go. Our guides on stairs in Ipoh terrace houses after surgery and the first week home after knee replacement go through the details.
What can I do this week?
Follow your surgeon’s exercise sheet and keep the visits to your surgeon. Beyond that, prepare the home so recovery is easier.
- Move what you use daily to waist height, so you do not bend or reach.
- Clear loose rugs and cables from the path to the bathroom.
- Put a firm chair with arms where you will sit for meals.
- Keep the walking aid within reach, even at night.
- Ask a family member or helper to be home for the first visit.
Our recovery goals worksheet helps you decide what to work towards, and the guide to daily activities after surgery covers dressing, showering and getting in the car.
When should you call the surgeon or go to hospital?
Contact your surgeon or the hospital where you had the operation if the wound opens or leaks, the knee becomes hot, red and very swollen, or you have a fever. Go to the emergency department for chest pain, breathlessness, or a calf that is swollen, hot and painful.
These signs need a doctor, not a physiotherapy session. Tell us afterwards so we can adjust the plan.
Home visit or our Canning Garden centre?
Home visits across Ipoh are available now, and they suit the first stretch of recovery, when travelling is tiring. Our Canning Garden centre near Fatimah Hospital is opening soon, and may suit you later if you want gym equipment and can travel comfortably.
Prices differ for home and centre, and we give a quote on WhatsApp after a short description. Our post-surgical rehabilitation page and home physiotherapy page show how both routes work.
