Targeted cell injections in Istanbul, placed where it hurts
How a biological preparation is delivered to one joint or tendon under image guidance, how our medical team confirms the target, and what recovery involves.
Targeted Injection Therapy at Our Istanbul Clinic
This page explains what targeted injection therapy is, how our medical team plans it, and what treatment in Istanbul involves. It is general information rather than a treatment plan: suitability is confirmed only after our team has reviewed your diagnosis, your records, the alternatives open to you, and the goals you want treatment to support.
At a glance
Targeted Injection Therapy at a glance
- Biological material
- A biological product placed into or near a defined joint, tendon or other anatomical structure, with identity, sterility and dose documented.
- How it is given
- Local injection, often image-guided, planned together with the anaesthesia, aftercare and rehabilitation that go with it.
- Where it sits today
- Accurate placement matters and we plan for it, though placement alone is not evidence that the injected product repairs tissue or changes pain and function.
- Who it may suit
- That is decided case by case. This page explains the treatment; suitability is confirmed only after our medical team has reviewed your records.
A local injection depends on the target and the technique
Targeted injection describes how something is delivered, not what it is. The illustration separates the target anatomy, the imaging guidance, the material injected, and the aftercare.

Clinical context

Microscopic research viewIllustrative detail
- Confirm the target
- Joint, tendon sheath, bursa, muscle, disc, or another structure, each chosen for a specific diagnosis rather than in general.
- Guide the needle
- Ultrasound or other imaging keeps the needle where it is meant to be, which is a question of accuracy rather than of product.
- Plan the recovery
- Medication, infection risk, loading, rehabilitation, warning signs, and follow-up are agreed with you before the procedure.
What Is Targeted Injection Therapy?
A targeted injection places the biological preparation directly into or beside the structure causing the problem: a knee, a hip, a shoulder, a facet joint in the spine, or a tendon such as the Achilles. Ultrasound or fluoroscopy is used while the needle goes in, so the physician can see the anatomy and place the material where it is meant to go rather than approximating from the surface.
Patients usually search for this by the joint that hurts - a knee stem cell injection, or a shoulder injection - and clinicians describe the same procedure as an image-guided injection. Whichever name brings you here, the questions are the same: which structure is actually generating the symptoms, what the imaging shows, and whether placing a preparation there serves the goal you have.
That is why our medical team starts with the diagnosis rather than the injection. We review your examination findings, imaging and the treatments already tried, and confirm that the proposed target accounts for your symptoms before anything is scheduled. The plan sets out the anaesthesia, what the day involves, the aftercare, and the rehabilitation that follows, and if surgery is the better answer for your joint we will say so. Send your imaging and examination reports for a medical case review and we will tell you which target, if any, we would inject.
How Targeted Injection Therapy Works
These are the biological ideas targeted injection therapy is built on. How much of it applies to you depends on your diagnosis, the goals set during your case review, the route of administration and the rest of your clinical picture, which is what our medical team works through with you.
- Delivery is local: the preparation is placed at one defined structure rather than being carried around the body
- Ultrasound or fluoroscopy shows the anatomy in real time, so the needle reaches the intended space and not the tissue beside it
- The biological rationale is the signalling: cells and platelets release messages that act on the tissue immediately around them, known as paracrine signalling
- Among those messages are growth factors, which are studied for the support they may give to the repair processes a tendon or joint runs for itself
- A temporary flare of pain or swelling can follow an injection, and the aftercare instructions cover what is expected and what is not
- Rehabilitation is part of the plan wherever the diagnosis calls for it, because loading and movement shape how the tissue responds
Stem cells and exosomes are different.
One is a living cell. The other is a cell-derived messenger. The difference shapes how each is sourced, how it is given, and which one our medical team may propose for your case.

- 01 / SOURCE
Living source cells
Mesenchymal stromal cells are living cells. Their behavior depends on source, handling, dose, and biological context.
- 02 / SIGNAL
Released signals
Cells release soluble factors and extracellular vesicles. Exosomes are one subset of these small vesicles.
- 03 / RESPONSE
Local cell response
Nearby cells may respond to those signals. That biological rationale is where treatment planning starts, not a promise of a result.
Your case review
How Our Medical Team Assesses Suitability
The purpose of the review is clarity. Your diagnosis, medical history, reports, imaging, current medication and the goals that matter to you give our team the context to plan treatment, or to tell you that this route is not right for your case.
- Osteoarthritis of the knee, hip or shoulder, confirmed on clinical assessment and imaging
- Rotator cuff disease and other shoulder injuries with a defined structural target
- Spinal facet joint pain and selected back pain presentations assessed by our medical team
- Achilles, patellar, elbow or other tendinopathy where the painful structure has been identified
- Suitability is confirmed after review of infection risk, anticoagulant medication, allergies and the other contraindications to an injection
Setting Realistic Goals for Your Treatment
Before treatment we agree on what we are aiming for: measures that fit your condition, a realistic period over which to review them, and what would count as no meaningful change. Goals are not predictions. Responses vary between patients and no clinical outcome can be guaranteed.
- Pain and function are recorded with validated measures before the injection, so the review compares two numbers rather than two impressions
- Goals are set for the treated structure, typically comfort, movement and what you can do in a normal day
- Pain fluctuates naturally in joints and tendons, so review points are spaced to show a trend instead of a single good or bad week
- Where surgery has been recommended, our team discusses it openly and will not present an injection as a way to avoid an operation you need
- Regenerative medicine is planned individually: responses vary between patients, no clinical outcome can be guaranteed, suitability is confirmed only after medical review, and treatment is planned alongside your existing care
Your next step
Find out whether targeted injection therapy may suit your case
If targeted injection therapy looks relevant to your diagnosis, the next step is a review of your own records by our medical team. If it does not, we can explain which of the other routes we plan may fit better.
Suitability is confirmed only after our medical team has reviewed your records, and treatment is planned alongside the care you already receive.

Targeted Injection Therapy - Frequently Asked Questions
Which areas do you treat with targeted injections?
Most commonly knees, hips, shoulders, ankles, spinal facet joints, and selected tendons such as the Achilles, patellar or elbow. Suitability depends on your imaging, the structure involved, and whether there is a clear anatomical target to aim at.
How is the injection guided?
With ultrasound for most joints and tendons, or fluoroscopy for spinal targets. The physician watches the needle reach the intended space, which is the point of image guidance: it is about accurate placement, not about making the preparation stronger.
Will it hurt?
Local anaesthetic is used, and most patients describe pressure during the injection. A flare of soreness in the following days is common and usually settles. Your aftercare instructions say what to expect, what to restrict and when to contact us.
Is rehabilitation part of the plan?
Where the diagnosis calls for it, yes, and you receive a written plan your local physiotherapist can pick up at home. How a joint or tendon is loaded afterwards matters, so rehabilitation is planned alongside the injection rather than left to chance.
When would we review the result?
At the points agreed before the injection, using the same pain and function measures recorded at baseline. Our team also tells you what would count as no meaningful change, and what the options would be at that stage.
Can this help me avoid joint replacement?
We do not present it that way. If a surgeon has recommended replacement, our medical team will discuss the reasoning honestly and, where surgery is the better answer for your joint, say so rather than schedule an injection.
How do I find out whether I may be suitable for treatment in Istanbul?
Send your confirmed diagnosis, recent reports and imaging, current medications and medical history to our patient coordination team. Our medical team reviews suitability case by case and tells you in writing whether this pathway fits your situation, and what it would involve.
How long do international patients stay in Istanbul?
It depends on the plan our medical team proposes: the procedure, the route, the monitoring, your mobility and the follow-up all affect it. Your written schedule states the number of days before you book flights or accommodation.
Is this treatment safe?
No medical treatment is free of risk, and we are direct about that. Our team reduces the risks that can be reduced: screened donor material, batch testing before release, administration by a physician in a clinical setting, monitoring during and after the procedure, and a written account of the side effects and contraindications that apply to your plan.
What results can I expect?
Your plan states a therapeutic goal and how it will be measured, not a promised outcome. Our medical team explains what change would be meaningful in your case, when it will be reviewed, and what we would do next if that review shows no benefit.
How much does treatment cost in Istanbul?
Pricing is case-specific: the material, the preparation and dose, the route, the number of sessions, the monitoring and any travel services all affect it. Our patient coordination team sends an itemized written estimate so you can see what each part of the plan costs before you commit.
What does the international patient program include?
Your estimate lists the medical review, tests, the procedure itself, monitoring, medications, airport transfers, accommodation arrangements, written discharge information and follow-up as separate lines, so you can see what is included and what is not.
How this guide is maintained
How This Guide Is Written and Reviewed
Editorial reviewHow this guide is reviewed
This guide carries a last-reviewed date. Review asks whether the way we describe targeted injection therapy and the research behind it still matches the published literature.
Where the evidence is limited, mixed or still emerging, the page says so rather than settling the question in the treatment's favour.
SourcingWhat we count as a source
Peer-reviewed human studies, trial registry entries and regulatory guidance. Laboratory and animal work is labelled as preclinical, and individual case reports are described as case reports.
Marketing material, including our own, is not treated as evidence.
Your treatment planWhat our medical team sets out
Before you agree to anything, our team can set out in writing the material proposed for your plan, how it is sourced, processed and release-tested, the route of administration, the monitoring plan, the full cost with exclusions, and who is clinically responsible for your care.
If any part of that is unclear, ask us. Your plan should make sense to you before you travel.
