Knee Replacement (Ghutna Badalna): When You Really Need It
You need a knee replacement (ghutna badalna) when pain from a worn-out joint limits your walking, sleep and daily life despite six months or more of proper exercise, weight work and the doctor’s other options, and the X-ray shows the cartilage is largely gone. Not before, and not because of age, a scan report or a neighbour’s opinion. Here is what the operation is, who really benefits, what to try first, and the questions to ask a surgeon.
The short version
- What it is: the worn ends of the thigh and shin bones are capped with metal, with a plastic spacer between; the knee is resurfaced, not “removed”
- Who it’s for: severe osteoarthritis with daily pain that limits walking and sleep, after months of exercise, weight loss and other treatment
- Not yet for: anyone who hasn’t done 3 to 6 months of strengthening, mild pain, or an X-ray showing only early change
- Recovery: walking with a frame day 1, stick by 4 to 6 weeks, most daily life by 3 months, full benefit at 6 to 12 months
- Honest limits: most are much better, some keep an ache, deep squatting is usually lost

What a knee replacement actually is
The word “replacement” frightens people, so start with what happens. The surgeon opens the front of the knee, shaves a few millimetres off the worn ends of the thigh and shin bones, and cements a metal cap to each, with a tough plastic insert between them as the new cushion. Ligaments, muscles and tendons stay. The knee still bends with your own muscles; only the grinding surfaces are new.
A total replacement caps the whole joint. A partial replacement caps only the worn half when the other half is healthy, giving a more natural feel, but not everyone qualifies. The operation takes one to two hours under a spinal or general anaesthetic, with three to five days in hospital. A modern implant is expected to last 15 to 20 years or more, which is why surgeons prefer to wait if a person is young and can be kept comfortable a few more years.
Who really needs it, and who doesn’t yet
An orthopaedic surgeon looks for all of these together, not one alone.
- Pain that runs your day. Most days, on walking a few hundred metres, on stairs, at rest in the evening and at night. Pain only after long walks is not there yet.
- Life shrinking. You’ve stopped going to the bazaar, the mosque or weddings because of the knee, or can’t get up from a chair without pulling on something.
- X-ray changes. Bone touching bone on the standing X-ray, with the gap on the inner or outer side gone. Early wear on a report (“mild degenerative changes”) is common after 50 and is not a reason to operate.
- Months of proper treatment done. At least 3 to 6 months of daily thigh and hip strengthening, weight loss if overweight, sensible shoes, pacing, and the doctor’s painkillers or an injection where offered. If not, the honest answer is “not yet”, because many people improve enough to postpone surgery for years.
- Fit enough for it. Sugar, BP, heart and weight in a range the anaesthetist accepts. Very high weight raises infection and clot risk and shortens implant life, so surgeons often ask for it to come down first.
Age alone decides nothing: fit people in their 80s do well, and someone of 50 with a joint destroyed by an old injury may need it early.
A replacement is chosen when the knee has stopped letting you live, not when the X-ray looks bad.
What to try first, honestly and for long enough
Every major guideline agrees on the first-line plan for knee osteoarthritis, and it isn’t a pill or an oil: stronger muscles and less load. No oil, plant, massage or diet fixes a worn knee for good or regrows cartilage; they are welcome alongside, for comfort.
- Strengthen, daily, for 12 weeks. Sit-to-stands from a firm chair without hands (10, three times a day), straight leg raises held 5 seconds (10, two sets), a wall sit at a half squat for 20 seconds (three times). Chair versions if the floor is out. Muscle effort is right; sharp joint pain is wrong. Results show at 6 to 12 weeks, not 6 days.
- Take load off. Each kilo lost takes roughly 4 kilos of load off the knee per step. Five kilos down is twenty kilos less on every stride. Our guide to knee pain and weight gives the how.
- Walk, in the right shoes. Flat ground, a firm cushioned sole, 10 minutes twice a day building to 30, at a pace that leaves the knee no worse next morning.
- Manage flares. Ice for a hot swollen flare, warmth for a cold stiff morning, 15 minutes each. Paracetamol as the pack says. An anti-inflammatory gel or tablet only as the pack or a pharmacist directs, and not for everyone with kidney, stomach, heart or BP problems.
- A stick, correctly. In the hand opposite the bad knee, tip level with the wrist crease when standing. It takes real load off and is not defeat.
- Injections, if offered. A steroid injection can give weeks of relief for a flare without changing the joint; other injections have weaker evidence. The doctor decides which, if any.
Warm oil massage, a hot towel and haldi in your food are fine as comfort; the laddu nuskha article explains why they sit beside the exercise, not instead of it.
Myth: after a knee replacement you never walk properly again
The opposite. Most people walk the day after surgery with a frame, and the point is to walk more than before. The myth comes from older operations with long bed rest, and from people who skipped physio. A replaced knee that isn’t bent and straightened daily in the first six weeks scars up; do the exercises and it moves.
Myth: you’re too old for it
Fitness, not age, is what the anaesthetist assesses. What a surgeon may say instead is “too young”, at 45, because the implant could wear out in a lifetime and a second operation is harder.
Myth: a “desi ilaj” can avoid it if you just find the right one
Exercise and weight loss are the only things with strong evidence for delaying or avoiding replacement, and they are as desi as walking. Any oil, majoon or powder that stops the pain within days almost certainly contains hidden steroids or painkillers, which raise your risk if you do end up in surgery.
Recovery, week by week, without the sugar-coating
| When | What’s usual |
|---|---|
| Day 1 to 3 | Standing and a few steps with a frame; pain controlled with the hospital’s medicines; bending exercises start |
| Week 1 to 2 | Home, walking indoors with a frame, swelling and bruising normal, daily physio exercises, poor sleep |
| Week 3 to 6 | Stick outdoors, stairs with a rail, knee bending past 90 degrees, stitches out around 2 weeks |
| Month 2 to 3 | Most daily tasks, driving when you can brake hard (often 6 weeks), light housework, short bazaar trips |
| Month 6 to 12 | Full benefit; warmth, clicking and mild stiffness may linger and are normal |
What most people are not told: a replaced knee often bends to about 110 to 120 degrees, not the 150 needed to squat fully or sit cross-legged, so namaz on a chair, a raised toilet seat and a stool for floor tasks become permanent. Some keep a dull ache or warmth in the joint for a year, and roughly one in ten remain disappointed, usually because pain relief was less than hoped. For a truly worn knee it’s still a good trade for most.
Cost, and the questions to ask the surgeon
Prices vary by city, hospital and implant brand, so no single figure is honest: from subsidised or free in some public and charitable hospitals, with waiting lists, to several lakhs per knee privately for imported implants. Ask for a written all-in estimate covering implant, surgeon and anaesthetist fees, hospital stay, medicines, first physio sessions and follow-up X-rays, and what happens to the bill if there’s a complication. A cheap unbranded implant is a place for hard questions. Then ask these.
- How many knee replacements do you do a year? (Dozens or more is reassuring.)
- Does my X-ray and my story justify it now, or should I do 3 more months of exercise and weight work first?
- Total or partial, and why?
- What are my specific risks with my sugar, BP, weight and heart?
- Who does my physio, how often, and for how long?
- What will I be able to do at 6 weeks, 3 months and a year, and what won’t come back?
- What’s the total cost, and what if something goes wrong?
Before surgery, sugar must be under control; tell the team every medicine, including blood thinners, steroids, herbal products and any “desi dawa”, and never stop or change a prescribed medicine on your own for the operation. After surgery, get seen the same day for a wound that leaks, reddens or smells; fever or chills; a knee that suddenly becomes hot, swollen and far more painful (possible infection, an emergency in a replaced joint); calf pain or swelling, or breathlessness or chest pain (possible clot, call emergency services); or a knee that gives way or won’t bend as far as it did the day before. Keep the wound dry, no oil or haldi on it, and no massage over the joint until the surgeon says so. Later in life, mention the implant before any dental work or infection, since bacteria can seed a replaced joint.
Knee replacement questions people ask
At what age is knee replacement done?
Most are done between 60 and 80, but age is not the deciding factor; pain, function, X-ray and fitness are. Surgeons are cautious under 55 because the implant may wear out in the person’s lifetime, and over 80 only if the heart, lungs or kidneys can’t take an anaesthetic.
Is knee replacement the only option for severe osteoarthritis?
No. Even with bone-on-bone X-rays, daily strengthening, weight loss and a stick help many people enough to delay surgery by years. Replacement is chosen when those have been done properly and the knee still runs your life.
How long does knee replacement recovery take?
Walking with a frame from day one, a stick outdoors by four to six weeks, most daily tasks by three months, and the full result at six to twelve months. Daily bending and straightening exercises in the first six weeks decide how well the knee moves for life.
Can I sit cross-legged or do namaz on the floor after knee replacement?
Usually not fully. A replaced knee commonly bends to about 110 to 120 degrees, short of the deep bend the floor needs. Namaz on a chair is the norm. Some implants and some people manage more, so ask your surgeon before the operation rather than after.
How long does an artificial knee last?
Most modern implants are working well at 15 to 20 years, many longer. Weight, activity choices and avoiding infection all affect it, which is why surgeons prefer to delay in younger people and get weight down first.
Is knee replacement safe for diabetics?
Yes, with sugar well controlled before and after; the team will want a recent HbA1c. Infection and slow wound healing are the extra risks. Never adjust insulin or tablets around the operation without the doctor’s instructions.
Can exercise really help me avoid a knee replacement?
For many people, yes, or at least postpone it by years. Twelve weeks of daily thigh and hip strengthening, plus weight loss where needed, is the treatment with the best evidence for a worn knee. It doesn’t regrow cartilage; it makes the joint better supported and less painful.
What can I not do after a knee replacement?
Running, jumping and contact sports are discouraged because they wear the implant, and deep squatting is usually lost. Walking, swimming, cycling, stairs, gardening and travel are all expected and encouraged.
Whatever you decide, the exercise and weight work in the Desi Remedies knee series is never wasted: it makes surgery less likely, and recovery faster if you have it.
