Physiotherapy After Knee Replacement Surgery: Week-by-Week Recovery Plan

A total knee replacement (TKR) can relieve years of arthritis pain, but the new joint only works well if the muscles around it are retrained. Structured physiotherapy after knee replacement helps you regain movement, walk confidently and return to daily activities. This week-by-week plan explains what usually happens — always follow your surgeon’s and physiotherapist’s specific instructions, as protocols can vary.

Why physiotherapy after knee replacement matters

After surgery, the knee is swollen and the thigh muscles “switch off” because of pain. If movement is not regained early, scar tissue can make the knee stiff, making stairs, sitting cross-legged and even walking difficult. Regular exercise from the first days prevents stiffness, rebuilds strength and lowers the risk of complications such as blood clots.

Week-by-week recovery plan

Days 1–3 (hospital)

• Ankle pumps (moving the feet up and down) every hour while awake to help circulation
• Quadriceps sets and gentle heel slides
• Standing and first walks with a walker, under supervision
• Learning to get in and out of bed and use the toilet safely

Weeks 1–2 (home)

• Goal: knee straight when lying, bend gradually increasing
• Heel slides, seated knee bends, straight-leg raises, short-arc quads
• Walking several times a day with the walker, slowly increasing distance
• Ice and elevation for swelling after exercise

Weeks 3–6

• Progress from walker to stick as balance and strength improve (as advised)
• Stationary cycling once knee bend allows
• Step-ups on a low step, mini squats with support
• Practising stairs: “up with the good, down with the operated”

Weeks 6–12

• Walking without an aid for most people
• Strengthening with resistance bands, balance training on one leg
• Return to most household tasks, short journeys and light work

3 months onwards

Strength and endurance continue to improve for several months. Low-impact activities such as walking, cycling and swimming are encouraged; ask your surgeon before high-impact sport.

Key exercises after knee replacement

1. Ankle pumps – Move your feet up and down briskly 20 times every hour.
2. Quadriceps sets – Tighten the thigh to press the knee down. Hold 5 seconds, 10–15 times.
3. Heel slides – Lying on your back, slide the heel towards your buttock to bend the knee, then straighten. 10–15 times.
4. Straight leg raise – Tighten the thigh and lift the straight leg about 30 cm. 10 times.
5. Seated knee bend – Sit on a chair and slide the foot back under the chair as far as possible, hold 10 seconds. 10 times.
6. Knee straightening stretch – Rest your heel on a rolled towel with nothing under the knee and let the knee straighten for 5 minutes. Never place a pillow under the knee for long periods.

Physio tip: Take pain medicine as prescribed about 30–45 minutes before exercise sessions. Controlled pain lets you do the exercises properly — and that is what prevents stiffness.

Managing pain and swelling

• Ice the knee for 15–20 minutes after exercise (wrap ice in a cloth — never directly on skin).
• Elevate the leg with the whole leg supported, keeping the knee straight.
• Spread activity through the day rather than doing everything at once.
• Some warmth and swelling for several weeks is normal and gradually decreases.

Warning signs — contact your surgeon or hospital

• Increasing redness, heat, discharge or opening of the wound
• Fever or chills
• New calf pain, tenderness or swelling (possible blood clot)
• Sudden chest pain or breathlessness — call emergency services
• A sudden increase in pain or inability to bear weight after a fall

Preparing your home

• Arrange a firm chair with armrests and a height that keeps your hips above your knees.
• Use a Western-style toilet or a raised toilet seat for the first weeks.
• Remove loose rugs, cables and clutter from walking paths.
• Keep frequently used items within easy reach to avoid bending.
• If possible, set up the bedroom on the ground floor for the first few weeks.

Returning to driving, work and daily life

Most people return to light household tasks within a few weeks. Office work is often possible after about 4–8 weeks, while physically demanding jobs take longer. Driving a car is usually only advised once you can bend the knee well, react quickly in an emergency stop and no longer need strong pain medicine — your surgeon will guide you. Riding a two-wheeler needs good balance and strength to support the vehicle when stopping, so discuss the timing with your surgeon and physiotherapist.

Prehab: preparing before surgery

If you are waiting for knee replacement, strengthening exercises before surgery (“prehab”) often make recovery easier. Our knee osteoarthritis exercise guide is a good starting point.
