The short answer: for orthopedic and pain conditions, stem cell therapy is generally not FDA approved. According to the FDA, the only stem cell products approved for use in the United States are blood-forming (hematopoietic) cells derived from umbilical cord blood, approved for disorders affecting the production of blood — not for joint, back, or other orthopedic uses. Most regenerative applications for pain are considered investigational, meaning the evidence is still developing and the products are not approved for those specific uses. That does not make them automatically unsafe or illegal, but it does mean patients should approach them carefully and informed. This guide explains the regulatory status, the safety picture, the risks, and exactly what to ask a clinic.

Key takeaways

The only FDA-approved stem cell products are cord-blood-derived blood-forming cells for blood-production disorders — not 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. According to the FDA, the only stem cell products currently approved for use in the United States consist of blood-forming stem cells (hematopoietic progenitor cells) derived from umbilical cord blood, approved for disorders affecting the production of blood — not for orthopedic uses. 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.

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.

What 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 2020 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.

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?

This is exactly where Regenerative Treatment Guide helps: rather than steering you to any single clinic, we match you with verified, board-certified providers based on your condition and location, so you can have an informed conversation.

Frequently asked questions

Generally, no — not for orthopedic or pain conditions. According to the FDA, the only stem cell products approved for use in the United States are blood-forming (hematopoietic) cells derived from umbilical cord blood, approved for disorders affecting the production of blood. The FDA states that regenerative products such as stem cells, exosomes, adipose-derived products, Wharton's jelly, 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. Most orthopedic and pain uses remain investigational.

There is a wide gap between how these treatments are marketed and what the FDA has actually approved. Some procedures using a patient's own minimally manipulated tissue may be regulated differently, but the FDA has repeatedly cautioned consumers that many stem cell and regenerative products marketed for orthopedic conditions are unapproved and that their safety and effectiveness have not been established. The agency has also taken enforcement action against some clinics. Investigational does not mean illegal, but it does mean unproven.

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. Unapproved or improperly processed products carry added risk, which is why sourcing and provider quality matter.

Reported risks include infection, immune or allergic reactions, bleeding or pain at the injection site, and problems linked to unapproved or contaminated products. The FDA has warned that some patients have been harmed by unproven stem cell treatments. Because protocols are not standardized, risks vary by product and provider. Discuss potential side effects and how a clinic screens and processes its biologics before any procedure.

No. The FDA has stated that there are currently no approved exosome products. The agency has specifically warned consumers about unapproved exosome products marketed for a range of conditions. Any exosome treatment offered for orthopedic or pain conditions should be considered investigational.

Offering certain regenerative procedures is not automatically illegal, but marketing unapproved products for unproven uses can violate FDA regulations, and the FDA has taken action against clinics that do so. Separately, any physician treating you must be licensed by your state medical board. The practical takeaway for patients: confirm the regulatory status of the specific treatment, and choose licensed, board-certified providers.

Ask whether the specific treatment is FDA-approved or investigational for your condition, what cells or product are used and where they are sourced and processed, whether the lab is FDA-registered, what the realistic expected outcomes and risks are, and what the total cost is. Be cautious of any provider that promises a guaranteed cure or dismisses these questions.
