Stem cell therapy for knees in Turkey: what you should know before you book
Stem cell knee treatment means injecting cells taken from your own body, usually from bone marrow or fat, into a painful knee to relieve pain and slow the damage of osteoarthritis. It is offered in many countries as a way to postpone or avoid a knee replacement. It is important to say at the start that this is not established standard care: studies show that some people feel less pain for a time, but they do not show reliably that cartilage regrows, and many professional bodies advise against routine use outside research. On our site stem cell knee treatment in Turkey starts at €2,510 at an accredited hospital.
This guide explains how the treatment works, who is offered it, what research shows, what it costs, which alternatives exist and what to ask a hospital. A quote is free, and a specialist looks at your scans before any plan is made.
What is stem cell knee treatment?
The cells used in knee treatment are usually mesenchymal stromal cells (often called mesenchymal stem cells) or a mix of cells and growth factors. They come from three main sources:
- Bone marrow: marrow is drawn from the hip bone, concentrated in a centrifuge, and the concentrate (bone marrow aspirate concentrate, BMAC) is injected into the joint.
- Fat tissue: a small amount of fat is taken from the abdomen or thigh, processed and injected. Some clinics inject the processed fat itself; others grow the cells in a laboratory.
- Donor or umbilical cord cells: some clinics offer these. Rules for such products are stricter in many countries, and you should ask whether the product is approved and where it was made.
The cells are thought to act mainly by releasing substances that reduce inflammation in the joint, rather than by turning into new cartilage. That is one reason the results are modest and vary from person to person. Stem cell therapy is not the same as PRP, which injects plasma with growth factors; you can read about it in the PRP treatments section.
Who is it offered to, and who should not have it
Stem cell injections are usually offered to adults with mild to moderate knee osteoarthritis (arthrosis) who still have some cartilage, and sometimes to people with cartilage injuries or after sports injuries. Your doctor reviews your X-rays or MRI first. Reasons it is usually not recommended:
- severe osteoarthritis with bone rubbing on bone, where the realistic option is a knee replacement;
- an active infection, a blood-clotting disorder or blood thinners that cannot be paused;
- a current or past cancer, unless your oncologist agrees;
- a knee problem that needs a different operation, such as a torn ligament, a locked meniscus or a deformity that needs correcting.
Bring your scans and ask for an honest view of whether a stem cell injection fits your knee, or whether another treatment would help you more.
How the treatment is done
- Collection: under local anaesthesia, with or without light sedation, the doctor takes bone marrow from the pelvis or fat from the abdomen. This takes about 20 to 30 minutes.
- Processing: the sample is processed in the hospital's laboratory or treatment room for about an hour, to concentrate the cells.
- Injection: the preparation is injected into the knee joint, often under ultrasound guidance so it reaches the right place. The doctor may inject more than one point.
- After: you rest briefly and usually go home the same day.
The treatment takes a half day. Some protocols repeat it after a few months, which affects the total cost.
What does the research show?
The research on stem cell therapy for knees is growing, but is still mixed. Several clinical trials report that pain and function improve over six to twelve months in some patients, and MRI studies show small changes in a minority. Other trials show no more benefit than a placebo injection or than hyaluronic acid. Study methods, cell types and doses vary so much that results cannot be compared directly, and there is no proof that the treatment delays knee replacement.
Several guideline bodies, including the American College of Rheumatology and the Arthritis Foundation in their 2019 osteoarthritis guideline, advise against stem cell injections for knee osteoarthritis outside research, and regulators such as the US Food and Drug Administration have warned patients about unapproved stem cell products. So what does this mean for you?
- Treat any promise of "regrown cartilage" or a cure with caution; ask for published results with a comparison group.
- Ask which cells are used, where they come from and whether the product is approved or part of a registered trial.
- Try established options first or alongside it, as they have better evidence and cost less.
How much does stem cell therapy for knees cost in Turkey?
Stem cell knee treatment starts at €2,510 on our site, and the hospital list shows its price in your currency. The price depends on the cell source, whether both knees are treated, the number of sessions, and what is included. The other figures in the table are approximate and confirmed only in a written quote.
| Country | Typical price per knee (approximate) | Notes |
|---|---|---|
| Turkey | from €2,510 | Hospital price for international patients; ask what scans and follow-up are included |
| United Kingdom | about £3,000–£8,000 | Offered privately by some clinics; not an NHS treatment |
| United States | about $3,000–$10,000 | Usually self-pay; insurance seldom covers it |
| Germany | about €3,000–€8,000 | Availability varies; usually self-pay |
Stem cell knee injections cost less than a joint replacement, but they are not a substitute for one, and a repeat injection may be needed. Insurance and health services rarely pay. At our hospitals you pay the hospital directly, and a quote commits you to nothing.
Alternatives to stem cell injections
| Option | What it does | Evidence and notes |
|---|---|---|
| Weight loss and physiotherapy | Reduces load on the knee and strengthens the muscles | Recommended first for knee osteoarthritis in major guidelines |
| Corticosteroid or hyaluronic acid injection | Short-term pain relief | Months of relief for some patients; established and inexpensive |
| PRP injection | Plasma with growth factors injected in the joint | Some evidence of benefit in mild to moderate arthrosis; simpler than stem cells |
| Stem cell injection | Cells or concentrate injected in the joint | Experimental; mixed evidence |
| Tibial osteotomy | Realigns the leg to move load off the worn part | For selected, usually younger patients with bow legs |
| Total knee replacement | Replaces the worn joint | Established treatment for severe arthritis |

Your trip to Turkey, recovery and risks
Plan 3 to 4 days in Istanbul: assessment and scans, the collection and injection on one day, and a check before you fly. Our how it works page explains how a quote becomes a booking. Expect a sore, swollen knee and some pain at the collection site for a few days. Most doctors advise rest for 24 to 48 hours, then gentle walking and physiotherapy; heavy sport and impact are avoided for several weeks. Any benefit usually builds slowly over weeks to months.
The risks are those of the procedure: pain and swelling, bleeding or bruising at the collection site, joint infection (rare, but serious), allergic reaction to additives and, with donor or laboratory-grown cells, the risk linked to the product. Clinics that treat several joints with one preparation and give several injections at once raise the risks. Your doctor should list the risks for your own case in writing.
How to choose a hospital, and what to ask
Choose a hospital, not a stand-alone clinic, with an orthopaedic team who examine your knee, review your imaging and are willing to tell you if you should not have the treatment. Ask: Which cells and which method are used? Is the product approved, and where is it processed? How many knees has the team treated? What outcome do you measure, and what is the price of a repeat? Do not pay a deposit before you have a written plan. Compare hospitals on our hospitals page and read our guide to choosing a safe doctor in Turkey. The overview of orthopaedics lists the other knee options.

On our site it starts at about €2,510 at an accredited hospital, shown in your currency on this page. The final price depends on the cell source, the number of knees and sessions, and is confirmed in a written quote.
Some patients report less pain for six to twelve months, but trials are mixed and there is no reliable proof that cartilage regrows. Several guideline bodies advise against routine use outside research.
Serious complications are rare. The risks are pain, swelling, bleeding at the collection site and, rarely, joint infection. Risks are higher with unregulated or donor products, so ask what is injected and whether it is approved.
Most often your own bone marrow concentrate or cells from your own fat. Some clinics offer donor or umbilical cord products, which need extra checks.
Adults with mild to moderate osteoarthritis who still have some cartilage. It is usually not suitable for bone-on-bone arthritis, active infection or untreated cancer.
Collection takes 20 to 30 minutes, processing about an hour and the injection a few minutes. You usually go home the same day.
Plan 3 to 4 days for assessment, treatment and a check before you fly.
Any improvement usually builds over weeks to months, and some people feel nothing. Judge the result after about three to six months.
There is no clear proof that it is. Both are injections with mixed evidence; PRP is simpler and cheaper, so some doctors try it first.
It may delay surgery in some people, but there is no proof that it does. If your knee is severely worn, a replacement is the established option.
