Physiotherapy at home after knee replacement: what to expect
After a knee replacement, physiotherapy at home helps you bend and straighten the new knee, rebuild thigh strength, and walk, climb stairs and use the toilet safely again. A physiotherapist assesses you, sets exercises that match your surgeon’s instructions, and progresses them as you recover, while daily practice between sessions does most of the work.

Key points
- Your surgeon’s protocol comes first; the physiotherapist builds the programme around it.
- The early goals are straightening the knee fully, bending it further each week, and walking safely with support.
- Exercises done every day between sessions matter as much as the sessions themselves.
- A painful swollen calf, breathlessness, fever or a leaking wound need a doctor promptly.
Why is physiotherapy important after knee replacement?
The operation replaces the worn joint, but the muscles around it are weak and the knee is stiff and swollen afterwards. Physiotherapy restores the movement and strength you need to use the new knee, and without it the knee can stay stiff.
Physiotherapy usually begins in hospital, often very soon after surgery, as the surgical team decides. Home sessions continue that work once you are discharged, which is especially useful in the first weeks when travelling to a clinic is tiring and getting in and out of a car is difficult.
Treatment at home also lets the physiotherapist see the real obstacles, such as the height of your bed, the steps to the bathroom and the toilet you use, and train you on them directly.
What happens in the first home session?
The first session is mostly assessment: the physiotherapist reads your discharge summary, asks about pain and sleep, measures how far the knee bends and straightens, checks the wound area and swelling, and watches you stand and walk. They then teach a small set of exercises to do every day.
- Keep the discharge summary and the surgeon’s exercise or precaution sheet ready.
- Take pain relief as prescribed, timed so it is working during the session if your doctor agrees.
- Wear shorts or loose trousers that roll above the knee.
- Have your walker or crutches, and the shoes you walk in, nearby.
- Ask a family member to watch, so someone else knows the exercises too.
What exercises are usually done?
Early exercises usually work on circulation, thigh-muscle control, and bending and straightening the knee, for example ankle pumps, tightening the thigh muscle with the leg straight, straight-leg raises and heel slides. Your physiotherapist decides which exercises suit you, how many to do and when to progress.
As the weeks pass, exercises usually move towards standing work: mini squats holding a support, step-ups, balance practice, and walking longer distances with less support. Do not add exercises from videos or copy another patient’s programme, because the right progression depends on your knee and your surgeon’s instructions.
Some pain and swelling during and after exercise is expected. Your physiotherapist will explain what level is acceptable, and may suggest elevation or cold packs to help with swelling, as your surgeon allows.
How to set up your home after knee replacement
Make the route from bed to bathroom clear, well lit and free of loose rugs and wires, use a firm chair with armrests, and raise low seats and toilets where you can. Ask your surgeon before sitting on the floor, squatting or sitting cross-legged, because many advise avoiding these, at least in the early months.
- Western-style toilet, or a commode chair or raised toilet seat over an Indian-style toilet.
- A non-slip mat and a plastic chair or stool in the bathroom, with a hand shower if possible.
- A bed high enough that your hips are level with or slightly above your knees when you sit on the edge.
- A night light on the way to the bathroom.
- Everyday items moved to between waist and shoulder height, so you do not bend low or climb.
Walkers, commode chairs and similar aids are often needed only for a few weeks, which is why many families rent rather than buy. You can browse walkers, commodes and other mobility aids to buy or rent where they are available.
Stairs
The usual rule is to lead with the non-operated leg going up and with the operated leg going down, holding a rail. Your physiotherapist will practise the stairs in your own home with you before you try them alone.
Warning signs to report
Tell your surgeon promptly about pain, swelling or warmth in the calf, a fever, a wound that is red, leaking or opening, or a sudden increase in knee pain. Chest pain or sudden breathlessness is an emergency. Call 108 or go to the nearest hospital.
- Calf pain or swelling, which can be a sign of a blood clot.
- Redness spreading around the wound, discharge or a bad smell.
- Fever or chills.
- Being suddenly unable to put weight on the leg, or the knee giving way.
- A fall, even if you feel fine afterwards.
If you went home on blood-thinning injections or wound dressings, a home nurse can give the injections and change the dressing as prescribed.
How long does recovery take?
Recovery varies widely. Many people walk with less support within the first weeks, but strength and bending usually keep improving for several months, and your surgeon will tell you when to expect to drive, climb stairs freely or return to work.
Sessions are usually more frequent early on and taper as you become confident with your exercises. Age, strength before surgery, other health conditions and how consistently exercises are done all affect progress, so avoid comparing yourself with someone else’s recovery.
Families help most by making daily practice easy: reminding, counting, walking alongside, and keeping the floors clear, but not by pushing exercises harder than the physiotherapist has advised.

Frequently asked questions
When should physiotherapy start after knee replacement?
Usually in hospital, often very soon after surgery, as the surgical team decides. Home physiotherapy then continues after discharge, following the surgeon’s instructions.
How many physiotherapy sessions are needed after a knee replacement?
There is no fixed number. It depends on your progress and your surgeon’s protocol; sessions are usually more frequent early on and reduce as you manage your exercises confidently.
Can I sit cross-legged or on the floor after knee replacement?
Ask your surgeon. Many advise avoiding floor sitting, squatting and sitting cross-legged, at least in the early months, and the advice can differ with the type of implant and your recovery.
Is it normal for the knee to be swollen during physiotherapy?
Some swelling is common for weeks after surgery. A sudden increase in swelling, redness, warmth or fever, or a painful swollen calf, should be reported to your surgeon promptly.
How long is a home physiotherapy session?
On Aish Health, sessions can be booked for 30, 45 or 60 minutes. A longer first session leaves time for assessment and teaching exercises.
