At a glance
Who it's for: Anyone preparing for or recovering from a total or partial knee replacement, most often for knee osteoarthritis.
Main goals: A straight knee, a good bend, walking without aids, stairs, the car, and getting back to work, walking or golf.
Typical recovery: Many people walk without aids from about 6 weeks. Full recovery takes several months, sometimes up to a year.
Sessions: Most people need 8 to 12 over 3 months, plus 2 to 4 before surgery if you start with prehab.
Avoid: A pillow under your knee, sitting still for long periods, and skipping your bending exercises.
Get urgent help: Chest pain or difficulty breathing: call 999. A hot, oozing wound or throbbing calf pain: get an urgent GP appointment or call NHS 111.
A knee replacement swaps the worn surfaces of your knee for metal and plastic parts. The NHS says most knee replacements last about 25 years.
Most people go home 1 to 4 days after surgery. Full recovery can take several months or longer. What you do in those months has a big effect on how well your knee bends, straightens and feels.
Knee replacements are known for being harder work than hips in the early weeks. Stiffness is the main enemy. We help you get stronger before surgery, visit you at home at first, then rebuild your strength in clinic until you're back to the life you want.
🛠️ How we help after a knee replacement
Every knee replacement plan at Athos Physio follows the same three steps. What changes is where you are in your recovery and what you want to get back to.
Step 1. Prepare and plan
Whether you're weeks before surgery or weeks after it, we start by working out three things:
Where you are now: your knee bend and straightening in degrees, thigh strength, walking and balance, measured with tests we repeat.
What your surgeon has advised: whether you had a total or partial replacement, any limits on movement, and when your follow-up is.
What you want back: walking the dog, stairs without a rail, gardening, cycling, golf or getting back to work.
We show you on a 3D anatomy model what your new knee looks like and why bending early matters, so the plan makes sense.
Step 2. Get your knee moving
Home visits in the early weeks. If getting into town is hard, we come to you. We check your set-up and practise stairs, chairs and the car.
Bend and straighten. Heel slides, seated knee bends and towel stretches for a straight knee, little and often, as part of your custom rehab plan.
Wake up your thigh muscle. Quad squeezes and straight-leg raises, because the quads often switch off after knee surgery.
Ease the pain and swelling. Gentle soft tissue work around the thigh and scar, plus advice on ice, raising your leg and pacing.
Walking practice. From frame to crutches, then one stick, then no aids once you walk without a limp.
Step 3. Build strength and confidence
This is the part that makes the biggest difference to how well you walk and climb stairs long term.
Thigh and hip strength, from sit-to-stands and step-ups to split squats and leg press-style work.
Balance work, so you feel steady on kerbs, slopes and uneven paths.
Rehab on the gym floor. Being inside F45 NQ means we can use exercise bikes, step boxes, sleds and free weights once you're ready.
Return to activity, including longer walks, swimming, cycling, golf or gym work, guided by your surgeon's advice.
We finish when you're doing what you want with confidence, not just when the wound has healed.

🔍 What is a knee replacement?
In a total knee replacement, the surgeon makes a cut down the front of the knee and moves the kneecap aside. They remove the worn ends of the thigh bone and shin bone. Metal and plastic parts are fitted over both bones.
The NHS says the operation usually takes about 1 to 2 hours. You'll have either a general anaesthetic or a spinal anaesthetic, which numbs you from the waist down.
If arthritis affects only one side of the knee, a partial replacement may be possible. Only the damaged side is replaced. The cut is smaller and recovery is usually quicker.
Types of knee replacement surgery
Total knee replacement: both bone ends replaced with metal and plastic parts; the most common type. Getting the knee fully straight and bending past 90 degrees are the early goals.
Total knee replacement with kneecap resurfacing: a total knee replacement, plus a plastic surface on the back of the kneecap; NICE advises offering this with a total knee replacement. Rehab is the same.
Partial (unicompartmental) knee replacement: only one side of the knee replaced, usually the inner side; a smaller cut and usually a quicker recovery. NHS driving advice is 3 weeks, not 6.
Partial kneecap (patellofemoral) replacement: only the joint behind the kneecap replaced; less common. Stairs and squatting are the main focus.
We follow your surgeon's instructions exactly. If you're not sure what they are, we'll help you find out.
🔍 What causes a slow recovery?
Most people recover well. When recovery stalls, it's usually for reasons we can work on together.
Common reasons we see in Manchester
Not bending the knee enough in the first 6 weeks, when scar tissue is still forming.
A pillow under the knee, which feels comfortable but lets the knee stiffen in a bent position.
Weak thigh muscles, after years of arthritis pain and the shock of surgery.
Under-treated pain, which makes the exercises too hard to do well.
Stopping the exercises once the wound heals.
Other health conditions, such as diabetes, or arthritis in the other knee.
Myths about knee replacement recovery
"Rest is best." The NHS says starting your exercises early helps your long-term strength and movement.
"No pain, no gain." Some discomfort is normal. Pain that keeps rising after each session means we need to adjust the plan.
"It'll be like a hip replacement." Knees usually take longer. Pain often eases by 3 months, but some discomfort can last up to 12 months.
"The operation fixes everything." It fixes the joint surfaces. Your muscles still need rebuilding.
🧪 How we assess you before and after knee replacement
Your first session lasts 60 minutes, in clinic or at home, so there's time to assess properly and start treatment the same day.
Your story (10 to 15 minutes). Your surgery date and type, your surgeon's advice, how you're managing at home, and what you want back.
Safety screen. We check your wound, calf and general health for the warning signs listed on this page.
Knee bend and straightening. Measured in degrees with a goniometer, so we can track every session.
Thigh strength. A straight-leg raise and a check for quad lag, where the knee drops as you lift.
Walking assessment. How you walk with or without aids, including the timed up-and-go test.
Leg strength test. The 30-second sit-to-stand test, which we repeat to track progress.
Your plan. In plain English: what to work on this week, which aids to use, and how many sessions we expect.
We also ask you to fill in the Oxford Knee Score, a short questionnaire that tracks your recovery. You'll leave with the first two or three exercises of your custom rehab plan.
🛠️ Knee replacement rehab at Athos Physio
Every plan moves through four phases. How fast you move depends on your surgeon's advice and how your knee responds, not on the calendar.
Prehab (6 to 8 weeks before surgery). Go into surgery as strong and prepared as possible. Thigh and hip strength, keeping your knee moving, practising with crutches, setting up your home.
Protect and move (weeks 0 to 6). A straight knee, a bend past 90 degrees, safe walking. Quad squeezes, heel slides, towel stretches, sit-to-stand, walking with aids, stairs practice. Home visits if needed.
Strengthen (weeks 6 to 12). Walk without aids and build strength. Step-ups, mini squats, balance work, an exercise bike, longer walks.
Return to activity (3 months onwards). Get back to work, hobbies and sport. Split squats, sled pushes, gym work, walking distance, swimming, cycling or golf.
Straightening and bending: the two numbers that matter
In the first 6 weeks, we track two numbers. The first is how straight your knee goes. A knee that stays slightly bent makes walking harder and more tiring.
The second is how far it bends. You need about 90 degrees to get out of a chair easily, and more for stairs and cycling. We set targets for each week and adjust your exercises if you fall behind.
Your home programme
In the first weeks, your exercises take 10 to 15 minutes, 3 or 4 times a day. Hospital leaflets often advise holding a straightening stretch for 45 to 60 seconds, 3 or 4 times. Later, it's 4 or 5 exercises, about 20 minutes, most days.
Most people need 8 to 12 sessions over 3 months, often starting with home visits.
What helps recovery after a knee replacement?
NICE's joint replacement guideline (NG157) covers care before and after knee replacement. Its draft recommendations advise giving people advice on rehab before surgery, covering exercise, lifestyle and staying independent afterwards.
The draft also advises offering rehab within 24 hours of surgery. After you go home, it advises supervised rehab if you're struggling with daily activities or self-directed exercise isn't working.
For people with arthritis on only the inner side of the knee, NICE advises offering a choice of partial or total replacement. The NHS advises starting your physio exercises early, keeping your leg raised and avoiding long periods of standing.
Recommended: exercise and advice before surgery; starting rehab within a day of surgery; a daily home programme for bending, straightening and thigh strength; supervised rehab if you're struggling at home.
Less useful: a pillow under the knee, or long periods of sitting with it bent; stopping exercises once the wound has healed; running, jumping and contact sport, which hospital leaflets advise avoiding.
⏱️ How long does it take to recover from a knee replacement?
Going home from hospital: typical timing: 1 to 4 days after surgery.
Stitches or clips removed: typical timing: about 10 days.
Compression stockings: typical timing: at least 6 weeks for most people.
Walking without aids: typical timing: often from about 6 weeks, if you feel ready.
Follow-up with your surgeon: typical timing: about 6 weeks.
Driving: typical timing: at least 6 weeks after a total, or 3 weeks after a partial, once you can do an emergency stop.
Back to work: typical timing: usually 6 to 12 weeks, depending on your job.
Heavy housework, such as vacuuming or carrying shopping: typical timing: from about 3 months.
Swimming, cycling, golf: typical timing: usually from about 3 months, once your surgeon agrees.
Full recovery: typical timing: several months, sometimes up to a year.
These are guides. A partial replacement is usually quicker. Your surgeon's advice comes first, especially for driving and sport.
✅ Life after knee replacement
At home
Don't put a pillow under your knee. The NHS says you don't need a special sleeping position
Don't sit with your legs crossed for the first 6 weeks
Go up the stairs leading with your good leg, and down leading with the operated leg
Don't kneel on the new knee until your doctor says you can
Remove loose rugs and trailing cables to reduce the risk of falls
Getting back to work and driving
Desk workers often return at 6 to 12 weeks. Physical jobs usually take 3 months or more
Wait at least 6 weeks to drive after a total replacement, or 3 weeks after a partial
Only drive when you can do an emergency stop without hesitation, and tell your motor insurer first
Getting back to the gym and sport
Walking, swimming, cycling, dancing and golf are usually fine once you've recovered
Running, jumping and contact sports increase wear on the joint, so talk to your surgeon first
Build back gradually, adding roughly 10% more each week if your knee stays settled
Self-help
Do your bending and straightening exercises little and often, every day
Raise your leg when you sit, and avoid standing for long periods while your ankle swells
Use a wrapped ice pack for up to 20 minutes after exercise
Take painkillers as prescribed, so you can keep moving

❓ Knee replacement recovery FAQs
🚨 Physio, GP or A&E?
Most aches and stiffness after a knee replacement are safe to manage with physio. A few warning signs need a doctor quickly. This list follows NHS guidance.
Book a physio (no GP referral needed): stiffness, weakness or a limp that isn't improving; a knee that won't straighten fully, or won't bend past 90 degrees by 6 weeks (book a physio assessment; we'll contact your surgical team if needed); hip or back aches as you start walking more.
Call your GP urgently or 111: wound infection signs: a high temperature, feeling hot, cold or shivery, oozing or pus, or redness, swelling or pain that's getting worse (get an urgent GP appointment or call NHS 111; contact your surgical team too); DVT signs: throbbing or cramping pain in your leg (get an urgent GP appointment or call NHS 111).
Call 999 or go to A&E: pain and swelling in your leg with difficulty breathing or chest pain (possible pulmonary embolism) (call 999 or go to A&E now; don't drive yourself).
