What it is
"Regenerative medicine" is an umbrella term. For knee pain, it is often used for injections made from a person's own blood or tissue, or from donated tissue, including platelet-rich plasma, bone marrow concentrate, adipose (fat) or stromal vascular fraction (SVF) preparations, and products marketed as umbrella cord, Wharton's jelly, perinatal or exosome products. These are very different from one another, and the label alone does not tell you what is actually in a product.
Regulatory status matters here. In the U.S., the only FDA-approved stem-cell products are cord-blood-derived hematopoietic progenitor cell (HPC) products, used for certain blood and immune disorders in specialist transplant settings. Most clinic stem-cell treatments for the knee, including MSC, adipose/SVF, umbilical cord, Wharton's jelly and perinatal products, are not FDA-approved. No exosome product is FDA-approved, and the FDA has warned the public about unapproved stem cell and exosome products.
The evidence for these uses in the knee is limited or still investigational. Researchers continue to study them, but interest and marketing do not equal proven results. Calling a clinic "holistic" or "alternative" does not change a product's FDA status. Only a licensed clinician can decide what is appropriate for you after an evaluation.
How it’s traditionally been approached
Knee pain has many possible causes, including wear in the joint, injury to cartilage, meniscus or ligaments, overuse, inflammation, and issues in the hip, back or foot that change how the knee moves. Because the causes differ, a careful evaluation is usually the first step before any approach is considered.
Traditionally, care has often started with conservative approaches such as activity changes, physical therapy and exercise, weight management, supportive devices, and over-the-counter or prescription medicines. Clinicians may also use imaging, injections that are FDA-approved for the purpose, or procedures when they judge it appropriate.
Surgery, including arthroscopy or joint replacement, is another established path that surgeons discuss in certain situations. Each option has its own benefits, risks and limits, and the right choice depends on the individual. A licensed clinician can walk you through how these compare for your situation.
How the right provider may help
The right provider may help you sort through the noise. A visit generally begins with a history of your symptoms, a physical exam, and sometimes imaging or other tests. A good clinician explains what they think is going on, what is uncertain, and which options are standard, which are investigational, and which are not FDA-approved.
If regenerative options come up, you can ask questions such as: What exactly is this product and where does it come from? Is it FDA-approved for this use, and if not, why is it being offered? Is this part of a study registered on ClinicalTrials.gov with IRB oversight? What are the risks, the alternatives, and what happens if it does not help?
You can also check that the clinician is licensed with your state medical board, and ask for written informed consent that covers risks and alternatives. A trustworthy provider welcomes these questions, does not pressure you, and is comfortable with you taking time or getting a second opinion. Providers across orthopedics, sports medicine and interventional pain may be part of this conversation, and listed providers can be explored through Providers.plus.
The whole-person view
Body, mind and stress affect each other. Ongoing knee pain can disrupt sleep, limit activities you enjoy, and raise worry or frustration, and stress and tension can in turn make pain feel more intense or harder to cope with. Looking at the whole person, including movement, rest, mood and daily habits, can be a helpful complement to any joint-focused care.
Some people explore body-based support such as Somatic Experiences to build awareness of how they hold tension and move, and others find talk therapy through Therapists.plus useful for coping with long-term pain and the stress around decisions. These are not substitutes for medical evaluation, and they do not replace or compete with any other approach. They are options some people consider alongside care from a licensed clinician.

Keep in mind
- Most stem cell, MSC, adipose/SVF, umbilical cord, Wharton's jelly, perinatal and exosome products offered for knees are not FDA-approved, and the FDA has warned the public about unapproved stem cell and exosome products.
- Watch for red flags: claims that a treatment cures or "treats everything," paying to join a "clinical trial," testimonials offered in place of evidence, and pressure to travel abroad or across states for treatment.
- Verify the product's FDA status, confirm any study on ClinicalTrials.gov with IRB oversight, check the clinician's license with your state medical board, and get written informed consent covering risks and alternatives.
- Licensed professionals should guide your care. For emergencies, such as sudden severe swelling, a hot red joint with fever, or inability to bear weight after injury, call 911. If you are in emotional crisis, call or text 988.

Frequently asked questions
What is regenerative medicine for knee pain?
Regenerative medicine for knee pain is a general term for biologic treatments, such as PRP, bone marrow or fat-derived preparations, and stem cell therapy products, that are used in or near the knee. The term covers very different products with different regulatory status and evidence. A licensed clinician can explain what is being offered and why.
Is stem cell therapy for knee pain FDA-approved?
No, stem cell therapy for the knee is not FDA-approved in the U.S. The only FDA-approved stem-cell products are cord-blood-derived hematopoietic progenitor cell (HPC) products for certain blood and immune disorders. Most clinic offerings for joints are unapproved, so ask any provider about the product's FDA status.
Does regenerative medicine regrow cartilage or help me avoid surgery?
No one can promise that. Evidence for these uses in the knee is limited or investigational, and claims of cartilage regrowth or avoiding surgery should be treated with caution. A licensed orthopedic or sports medicine clinician can discuss realistic options for your situation.
Are exosome treatments for knees approved?
No, no exosome product is FDA-approved, and the FDA has warned the public about unapproved exosome products. If a clinic offers them, ask what the product is, where it comes from and whether it is part of a registered study with IRB oversight.
How do I find a safe regenerative medicine provider for knee pain?
Start by confirming the clinician's license with your state medical board and asking about the FDA status of every product. Look for clear written informed consent, honest discussion of risks and alternatives, and no pressure to decide quickly. Directories like Providers.plus can help you find licensed providers to compare.
What should I ask before trying a regenerative knee treatment?
Ask what the product is, whether it is FDA-approved for this use, and whether it is part of a study registered on ClinicalTrials.gov with IRB oversight. Also ask about risks, alternatives, and what happens if it does not help. Be cautious if you are asked to pay to join a "trial" or told it works for everything.
