Who this is for
If one of these is you, keep reading.
"It's just arthritis"
Knee osteoarthritis that keeps getting worse
Morning stiffness, swelling, stairs you avoid. You want more than learning to live with it.
"Cortisone stopped working"
Injections that wear off faster every time
Cortisone, hyaluronic acid or PRP helped for a while — and then the pain came back.
"Surgery for a meniscus?"
A meniscus tear you'd rather not operate on
Pain on the joint line, catching or swelling after twisting — and a surgeon already talking about arthroscopy.
"I used to run"
Former athletes with an old injury
Soccer, skiing, basketball, running. The injury was years ago. The knee never forgot.
"Bone on bone"
Advanced wear, and you were told options are running out
A specialist reviews your imaging first, so your plan is designed for your knee — before you spend anything.
Knee options, side by side
Shots cushion. A replacement removes. Stem cells work on the joint itself.
Hyaluronic acid lubricates. PRP gives a short boost. A replacement swaps the joint for metal and plastic. Stem cell therapy is designed to support your own knee's repair.
| Hyaluronic acid shots | PRP | Knee replacement | ★ The smart first stepStem cell therapy | |
|---|---|---|---|---|
| What it does inside your knee | Adds lubrication and cushioning | Growth factors from your own blood | Cuts out the joint and replaces it with metal and plastic | Works inside the joint to calm inflammation and support cartilage repair |
| Living stem cells | None | No stem cells | Not applicable | 50 million living stem cells |
| Stairs, walks and long days | Relief for a few months, then repeat | A short boost that often fades | Comes after weeks of rehab, with a new joint | Gradual improvement over 4–6 months, in your own knee |
| Time away from life | An appointment | An appointment | Hospital stay, then weeks to months of rehab | One treatment day. No hospital stay |
| Can you still choose a replacement later? | It is the replacement. No going back | One treatment could be enough, and the replacement is still an option later |

They were told to live with it. They didn't.
"My Dr. was friendly and nice. She explained to me each step of the procedure and addressed inflammation found on the day of the procedure as well as the standard injection site for my knees. For anyone who is considering surgery, please give this treatment a try."
"The facility and staff were very friendly and caring. Everything was detailed and handed to you in English. … She did the procedure in a safe and clean facility."

Knee FAQ
Your questions, answered.
Can stem cell therapy help me avoid a knee replacement?
For many patients with mild to moderate osteoarthritis, cartilage wear or meniscus damage, stem cell therapy is a way to treat the knee before an irreversible surgery. A specialist reviews your imaging first, so your plan is designed for your knee.
Am I a candidate if I've been told I'm "bone on bone"?
Send your X-ray or MRI. A specialist reviews it for free and shows you the plan designed for your knee — before you spend anything.
How much does stem cell therapy for knees cost?
Knee treatment in Medellín starts from $1,999 USD: the stem cells, the guided application in the operating room with local anesthesia, and a consultation with the doctor. The Marriott Hotel in the same building, airport transfers, sedation and exosomes can be added to your plan, and your coordinator sends that price in writing. Comparable treatments in the US typically run $20,000+. Your exact price is confirmed after your consultation.
Does it hurt?
The application is done under mild sedation or local anesthesia, so you stay comfortable. Afterward, you rest at the hotel, one elevator away, with your coordinator checking on you and clear post-care instructions in hand.
When will I see results?
Improvement builds gradually, typically between 4 and 6 months after your treatment, and some patients keep improving at 8 months. The cells release signals that may help calm inflammation and support repair.
How long do I need to stay in Medellín?
Most knee treatments are done in a single day; some plans add a second day, and your quote tells you exactly which one is yours. The doctors recommend staying at least 2 days after your application to rest at the hotel, and you can add extra nights to enjoy the city.
Can you treat both knees on the same trip?
Yes. Both knees — or a knee plus another joint — can be treated on the same procedure day. Your quote reflects exactly what's included.
Is stem cell therapy better than PRP or hyaluronic acid for knees?
They work differently. PRP uses growth factors from your own blood and hyaluronic acid adds lubrication; neither contains living cells. Stem cell therapy delivers 50 million young cells that may help calm inflammation and support tissue repair inside the joint.
Can stem cells treat a torn meniscus without surgery?
Many degenerative and partial meniscus tears can be treated without arthroscopy. The cells may help calm inflammation and support tissue repair. A specialist reviews your MRI, so your plan is designed for your tear.
Is there an age limit?
There's no fixed age limit. What matters is your overall health and the condition of the joint, reviewed in your online consultation.
Is it legal and safe?
Stem cell therapy is not approved by the FDA, but in Colombia it is legal. Your application is performed by specialist physicians in a fully-equipped operating room, under ultrasound guidance, by a team whose lead doctors have performed more than 8,000 procedures.
What can you expect?
Every body responds at its own pace; improvement is usually expected at 4–6 months. What you can expect is the quality of the cells, the precision of the application, and a medical team with you the whole way.
