Knee Injections (Ghutne Ka Teeka): Steroid, Hyaluronic Acid, PRP
Three injections are sold for knee pain (ghutne ka teeka): a steroid, hyaluronic acid (“gel” or “lubricant”), and PRP made from your own blood. The honest verdicts: steroid gives real but short relief for a flare, worth it in the right knee; hyaluronic acid gives modest relief for some and costs a lot, depends; PRP is uncertain, expensive and oversold, depends leaning towards skip. None of them fixes the joint for good, none regrows cartilage, and every one is a doctor’s decision in a sterile room.
Verdicts at a glance
- Steroid injection: worth it for a painful, swollen flare of arthritis; relief for weeks, not months; not repeated often
- Hyaluronic acid: depends; small benefit for some with mild to moderate wear, several injections, noticeable cost
- PRP: depends, leaning skip; evidence mixed, no standard preparation, priced like a miracle
- What every injection needs: a diagnosis first, sterile technique, and a strengthening plan alongside

The routine this takes apart
Knee hurts for months. A clinic offers “a teeka that will fix it”, often a course of three, priced per injection, sometimes without ever examining the knee. The person pays, feels better for a while, and comes back for the next course. Nobody mentions exercise, weight or shoes. Here is each injection judged on what it does, how long it lasts, what it costs, what it risks, and whether it changes the future of the joint.
Knee injections, step by step
1. Steroid (corticosteroid) injection Worth It
A strong anti-inflammatory placed inside the joint, usually with a local anaesthetic, to calm the lining of an inflamed, swollen, arthritic knee. Relief often starts within a day or two and lasts a few weeks to a couple of months, then fades. It is the best-studied of the three and the one most guidelines accept for a painful flare when tablets and exercise aren’t enough.
What it doesn’t do: change the cartilage or the X-ray. Repeated steroid injections into the same knee, more than a few a year, may soften cartilage over time, so doctors space them out and stop if they’ve stopped helping. Sugar rises for a few days in people with diabetes, and BP can nudge up; both are reasons to tell the doctor before the needle. Infection after a properly done injection is rare; after an injection in an unclean setting it is the leading cause of the hot, swollen, feverish knee that ends up in hospital.
Best use: a knee that has swollen and flared, to buy a comfortable window for exercise to start. Not a standing monthly appointment.
2. Hyaluronic acid (“gel”, “lubricant”, viscosupplement) Depends
Hyaluronic acid is a natural part of joint fluid, and the injection puts a thick version into the knee, sold as “oiling the joint”, as a single shot or a course of three to five a week apart. Any benefit takes a few weeks to start and, for responders, can last several months.
The honest reading: on average the benefit over a dummy injection is small; some guidelines advise against it, others allow it for mild to moderate wear in people who can’t take anti-inflammatory tablets. Some individuals do well, many notice little. It’s safe in trained hands, with a temporary flare in a few. The price per course is high for what it delivers, and “lubricant” is marketing; the gel is absorbed within days and any effect comes from calming the lining.
Reasonable if a doctor suggests it for early or moderate arthritis, money isn’t a hardship, and you go in expecting modest help rather than a new knee. Poor value for bone-on-bone knees.
3. PRP (platelet-rich plasma) Depends
Blood is drawn from your arm, spun to concentrate the platelets, and the plasma is injected into the knee, on the theory that growth factors in platelets help the tissue. It’s drug-free, which is part of the appeal.
The problems are practical. There’s no standard PRP: different machines, spin times and blood volumes give different products. Comparisons with hyaluronic acid or dummy injections are mixed, and the better-designed ones tend to show less. Most guidelines say the evidence isn’t strong enough to recommend it, and none say it regrows cartilage. It’s sold as a course of two or three, priced well above a steroid injection, and often repeated. Side effects are mostly a sore knee for a few days; infection risk is the same as any needle.
If you can afford to lose the money and want to try it after exercise and weight work are already in place, it’s unlikely to harm you. If the clinic promises cartilage regrowth or “avoiding replacement”, walk out.
4. “Stem cell”, ozone, homeopathic and unlabelled injections Skip It
Stem cell injections for knees remain experimental, are unregulated in most clinics offering them, and have caused serious infections. Ozone gas injections have no good evidence. Any injection whose contents the clinic can’t name, or that is drawn from an unlabelled vial, may be a steroid you weren’t told about, which matters if you have diabetes or later need surgery.
No.
5. The injection without a diagnosis Skip It
A knee that hurts because of a torn meniscus, gout, an infection, or pain referred from the hip does not need a lubricant, and a steroid into an infected joint is dangerous. An examination, a standing X-ray, and blood tests where gout or infection is possible come first. A clinic that injects on the day you walk in, without asking about fever, previous gout or your sugar, is selling injections, not treating knees.
Diagnosis first, always.
6. The strengthening plan that should come with every injection Worth It
The injection buys a window. What you do in the window decides the year. Daily sit-to-stands, straight leg raises and a wall sit, 12 weeks, plus each kilo lost taking roughly 4 kilos of load off the knee per step, is the treatment with the best evidence for a worn knee, and it’s the part clinics skip because nobody pays for it. Our knee pain and weight guide and the joints-need-loading article cover the how.
Free, and the only step that changes where the knee is in five years.
| Injection | Relief | Verdict |
|---|---|---|
| Steroid | Days to start, weeks to a couple of months | Worth it, for a flare |
| Hyaluronic acid | Weeks to start, months for responders | Depends |
| PRP | Uncertain | Depends, leaning skip |
| Stem cell, ozone, unlabelled | Unproven | Skip it |
| Any injection with no diagnosis | Risky | Skip it |
| Exercise and weight alongside | 6 to 12 weeks, lasting | Worth it |
What to ask before saying yes to any knee injection
- What exactly is in the syringe, by name? If the answer is vague, don’t proceed.
- What is my diagnosis, and how do you know it isn’t gout, infection or a torn meniscus?
- How long should the relief last, and how many injections a year is safe in my knee?
- Is the skin cleaned with antiseptic and is the needle fresh from a sealed pack? Watch.
- What happens to my sugar or BP over the next week, and should I check them more often?
- What is the total cost of the course, and what do you expect me to be doing for exercise while it works?
After any injection: rest the knee a day or two, ice 15 minutes if it swells, keep the puncture site clean and dry for 24 hours, and no oil massage over the joint for a few days. A sorer knee for a day is common; fever, heat, redness or pain still climbing after 48 hours is not, and needs the same-day rule below.
Myth: an injection fixes the knee for good, or avoids surgery
No injection changes the cartilage or the X-ray. A steroid quietens inflammation for a while; hyaluronic acid and PRP, at best, do the same more slowly. If pain limits life despite months of exercise, weight work and sensible injections, the honest conversation is about replacement, and injections are not a way around it. Anyone who says their injection “regrows the joint” is describing something no injection does. The one thing with real evidence for delaying replacement is the unglamorous plan in step 6.
Tell the doctor about diabetes (a steroid raises sugar for days; check more often that week and never adjust insulin or tablets on your own), high BP, blood thinners (bleeding into the joint), any allergy, a recent infection anywhere, previous gout, and any “desi dawa” you take, since some contain hidden steroids that stack with the injection. No injection into a knee that is already hot, red or feverish, or through broken or infected skin. Go to hospital the same day if, in the days after an injection, the knee becomes hot, red, much more swollen and painful, or you develop fever or chills: infection in a joint is an emergency. Pregnant or breastfeeding women should discuss any injection with their obstetrician. Children do not get these injections for growing pains or sports strains.
Knee injection questions people ask
Which injection is best for knee pain?
For a painful, swollen flare of arthritis, a steroid injection has the best evidence and the fastest effect. Hyaluronic acid suits some people with mild to moderate wear who want to avoid anti-inflammatory tablets. PRP has the weakest evidence of the three. “Best” depends on the diagnosis, which is why an examination comes first.
How long does a steroid injection in the knee last?
Relief usually begins within a day or two and lasts a few weeks to about two months, sometimes longer in a knee with a lot of inflammation, sometimes barely at all in a bone-on-bone knee. It is spaced out, not given monthly, and stopped if it has stopped helping.
Can a steroid injection raise blood sugar?
Yes. People with diabetes commonly see higher readings for three to seven days after a knee steroid injection. Check more often that week, keep to your usual medicines, and contact your doctor if readings stay high or you feel unwell. Never change insulin or tablets on your own.
Does a hyaluronic acid injection really lubricate the knee?
Not in the way it’s sold. The gel is absorbed within days; where it helps, it’s by calming the joint lining for a while. The average benefit over a dummy injection is small, some people respond well, and it’s poor value for a knee that’s already bone on bone.
Is PRP injection worth it for knee osteoarthritis?
The evidence is mixed and the product varies from clinic to clinic, so no one can promise you a result. It’s unlikely to harm you when done sterile, and unlikely to change the joint. Try it only with money you can afford to lose, after exercise and weight work are already in place, and never on a promise of cartilage regrowth.
How many steroid injections can you have in a knee?
Most doctors limit them to a few a year in the same joint, with a gap of several weeks to months between, because frequent steroids may soften cartilage and the benefit shrinks with each one. The doctor sets the number for your knee; it isn’t a home decision.
Can knee injections avoid knee replacement?
They can postpone the conversation by easing pain for a while, but they don’t change the cartilage or the X-ray. What genuinely delays or avoids replacement is months of thigh and hip strengthening and weight loss. Injections work best as a bridge into that, not as a substitute.
What are the side effects of knee injections?
A sore, swollen knee for a day or two is common with all three. Steroids can raise sugar and BP for days and, if repeated often, soften cartilage. Hyaluronic acid and PRP occasionally cause a painful flare. The serious risk with any needle is infection, which is rare with sterile technique and an emergency when it happens.
Injections are one small tool in a long game. The rest of the Routine Autopsy series takes other confident promises apart the same way.
