The short answer
- Is it FDA approved? Not for joint, back, or other orthopedic pain. The FDA has approved only a handful of stem cell products, all for blood disorders and one transplant complication.
- Is it legal? Physicians can legally offer some procedures, and Florida passed a 2025 law allowing certain unapproved stem cell therapies for orthopedic conditions, wounds, and pain. Marketing unapproved products can still break federal law, and state laws don't make a treatment FDA-approved.
- Is it safe? Generally considered low-risk with qualified physicians and properly processed cells, but not risk-free. The FDA has warned that some patients have been seriously harmed by unproven products.
For orthopedic and pain conditions, stem cell therapy is not FDA approved. Most regenerative applications for pain are investigational: the evidence is still developing, and no product is approved for those uses. That doesn't make them automatically unsafe or illegal, but it does mean you should approach them carefully and well informed. This guide explains what the FDA has approved, the legal picture (including new state laws), the safety risks, and exactly what to ask a clinic.
Key takeaways
- FDA-approved stem cell products are limited to cord-blood-derived blood-forming cells for blood-production disorders and, since December 2024, one MSC therapy for a transplant complication in children. None are approved for orthopedic conditions.
- There are currently no FDA-approved exosome products.
- Most stem cell, PRP, and other regenerative uses for pain are investigational and not FDA-approved for those uses.
- Procedures are generally considered low-risk with qualified providers, but no procedure is risk-free, and unapproved products add risk.
- Provider quality, honest expectation-setting, and transparent cell sourcing matter enormously.
What the FDA has — and hasn't — approved
The U.S. Food & Drug Administration regulates stem cell products, and generally all stem cell products require FDA approval. The FDA-approved stem cell products fall into two groups, and neither is for orthopedic use:
- Cord blood products. Blood-forming stem cells (hematopoietic progenitor cells) derived from umbilical cord blood, approved for disorders affecting the production of blood.
- Ryoncil (remestemcel-L). In December 2024, the FDA approved its first mesenchymal stromal cell (MSC) therapy. It's a donor bone-marrow product given by IV to children with steroid-refractory acute graft-versus-host disease, a serious complication of bone marrow transplants. It is not approved for joints, pain, or any orthopedic use.
Ryoncil matters because MSCs are the same cell type most orthopedic clinics talk about. Its approval shows the FDA will approve an MSC product when there's evidence for a specific use. It does not make MSC injections approved for knees or backs. (The FDA's consumer page, last updated in April 2024, still describes cord blood products as the only approved stem cell products; it predates Ryoncil.)
The FDA has also stated that there are currently no approved exosome products, and that regenerative products such as stem cells, exosomes, adipose-derived products, Wharton's jelly, umbilical cord blood, and amniotic fluid have not been approved to treat orthopedic conditions — including osteoarthritis, tendonitis, disc disease, tennis elbow, or back, hip, knee, neck, and shoulder pain. The FDA has repeatedly cautioned consumers about clinics marketing unapproved stem cell products. You can review the FDA's consumer guidance on stem cell therapies directly.
"FDA-approved" vs. "FDA-registered" vs. "FDA-cleared"
Clinic marketing often uses FDA language that sounds like approval but isn't:
- FDA-approved means the FDA reviewed evidence of safety and effectiveness for a specific use and licensed the product for that use. No stem cell product is approved for orthopedic conditions.
- FDA-registered means a lab or facility has registered with the FDA and lists the products it handles. Registration is a requirement for operating, not a review of whether the treatment works. "Processed in an FDA-registered lab" tells you about the facility, not the treatment.
- FDA-cleared usually applies to devices, such as some PRP preparation systems. Clearance of a device does not mean the treatment made with it is approved for your condition.
If a clinic describes a stem cell treatment for knee, back, or shoulder pain as "FDA-approved," that's a red flag. If it says "FDA-registered lab," ask what that does and doesn't mean.
Is stem cell therapy legal?
Legal and FDA-approved are different questions. In short: physicians can legally offer some regenerative procedures, but marketing an unapproved product to treat a disease can violate federal law, and the FDA has taken enforcement action against clinics that did so. Procedures that use your own tissue with minimal processing, for the same basic function it had in your body, may be regulated differently from manufactured drug products. The line is technical, and clinics don't always stay on the right side of it.
State laws: Florida and Texas
Some states have passed their own stem cell laws. These change what state medical regulators allow. They do not change FDA approval status or override federal law.
- Florida (SB 1768, effective July 1, 2025). Allows licensed physicians to use certain stem cell therapies that are not FDA-approved for orthopedic conditions, wound care, and pain management, within their scope of practice. The cells must come from facilities that are FDA-registered and accredited by specific organizations, embryonic and fetal cells are excluded, and patients must sign a consent form covering benefits and risks. Advertising must include a notice that the therapy has "not yet been approved" by the FDA. Legal analysts have noted the law conflicts with federal requirements (Holland & Knight).
- Texas (HB 810, 2017). Allows patients with a severe chronic disease or terminal illness to access investigational stem cell treatments that are being studied in clinical trials but aren't yet FDA-approved, on a physician's recommendation and with written consent. It is narrower than it's often marketed: it isn't a general permission for any clinic to sell stem cell injections for joint pain (Matthews et al., Stem Cells Dev 2018).
If you live in one of these states, a clinic may tell you the treatment is "legal here." That can be true under state law and still say nothing about whether the treatment works, or whether it's FDA-approved. See our Florida and Texas guides for state-specific details.
Why clinics still offer it: "investigational" vs. "approved"
If most orthopedic uses aren't approved, why are clinics everywhere offering them? The honest answer is that there is a wide gap between how these treatments are marketed and what the FDA has actually approved. Some procedures that use a patient's own minimally manipulated tissue may be regulated differently from manufactured drug products, but the FDA has been clear that many stem cell and regenerative products marketed for orthopedic conditions are unapproved and that their safety and effectiveness have not been established for those uses.
The key word is investigational. It does not mean illegal, and it does not mean worthless — it means unproven for that use. For patients, that distinction is the whole game: it's reasonable to consider an investigational option with a qualified physician, but it should be a careful, eyes-open decision, not a response to a guaranteed-cure advertisement.
Where PRP fits in the regulatory picture
Platelet-rich plasma (PRP) sits in a slightly different spot. PRP is prepared from your own blood, and some PRP preparation devices are FDA-cleared — but the FDA has not approved PRP as a treatment for orthopedic pain, hair loss, or skin rejuvenation. In practice, that means orthopedic PRP is investigational, hair-loss PRP is off-label, and aesthetic PRP is cosmetic. For a full breakdown, see our guide to PRP therapy and our hub on PRP for hair loss.
Umbilical cord and Wharton's jelly injections
Umbilical cord tissue, Wharton's jelly, cord blood, and amniotic products are among the most heavily marketed options. The FDA lists all of them among the regenerative products that have not been approved to treat orthopedic conditions. The only approved cord-derived products are the cord blood products for blood disorders described above. That's a different use, prepared and given in a different way. If a clinic offers an umbilical cord injection for a joint, ask exactly what product it is, who makes it, and whether it contains living cells. Many don't, even when they're marketed as "stem cells."
Are "stem cell patches" FDA approved?
No. Skin patches sold online as "stem cell patches" don't contain stem cells; they're marketed as ways to "activate" your own. No patch has been approved by the FDA to treat any disease or regenerate tissue. If a patch is listed with the FDA at all, that's a product listing, not a review of whether it works.

Take the Free AssessmentWhat the evidence actually shows
"Not FDA approved" is not the same as "no evidence." Research into regenerative medicine is active and growing — thousands of studies are indexed on PubMed, and hundreds of trials are listed on ClinicalTrials.gov. The strongest signal to date is for the knee: a 2021 meta-analysis of nine randomized controlled trials of stem cell therapy for knee osteoarthritis reported improvements in some pain and function scores. As the authors of such reviews consistently emphasize, study designs vary, sample sizes are often small, and larger, longer-term trials are still needed before firm conclusions can be drawn. For a fuller, sourced review, see our MSC research for orthopedic pain pillar and our complete guide to stem cell research.
Is stem cell therapy safe?
When performed by qualified, board-certified providers using appropriately sourced and processed cells, regenerative procedures are generally considered low-risk — but no medical procedure is risk-free. Risks and benefits vary by individual and by the specific product used, and they should be discussed with a licensed physician. Sourcing matters: reputable clinics use biologics processed in FDA-registered laboratories with rigorous screening, while unapproved or improperly processed products carry added risk.
Reported risks and side effects
- Infection at the injection site, particularly with improperly handled products.
- Immune or allergic reactions, more likely with products not derived from your own tissue.
- Bleeding, swelling, or pain at or around the injection site.
- Harm from unapproved or contaminated products — the FDA has warned that some patients have been seriously harmed by unproven stem cell treatments.
- Financial harm and false hope from clinics promising results the evidence doesn't support.
Red flags when evaluating a clinic
Because protocols aren't standardized and quality varies, knowing the warning signs protects you:
- Promises of a guaranteed cure or "miracle" results.
- Claims that a treatment "regrows cartilage" or is "FDA approved" for orthopedic pain.
- High-pressure sales tactics, large up-front payments, or financing pushed before evaluation.
- Vague or evasive answers about cell sourcing, processing, and FDA-registered labs.
- No board-certified physician performing the evaluation and procedure.
Questions to ask before any treatment
Turn your consultation into a screening tool. Bring these questions:
- Is this treatment FDA-approved or investigational for my specific condition?
- What exactly is being injected, and where is it sourced and processed? Is the lab FDA-registered?
- What are the realistic expected outcomes — and what does the evidence say for my condition?
- What are the risks and side effects, and how do you handle complications?
- Who performs the procedure, and what are their credentials?
- What is the total cost, and what happens if it doesn't work?
