What it is
Microfragmented adipose tissue, often shortened to MFAT, refers to fat tissue taken from a person's own body, usually through a minimally invasive collection, and then broken into smaller fragments using a processing device. The fragments keep some of the natural structure of the fat, including its supportive connective tissue.
Fat tissue naturally contains many kinds of cells and structural components, including cells sometimes described as mesenchymal stromal cells (MSCs). Because of this, MFAT is often grouped with adipose-derived cell procedures and is mentioned in conversations about stem cell therapy and regenerative medicine.
Regulatory status matters here. 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, used in specialist transplant settings. Most clinic-based adipose, SVF and MSC uses, including microfragmented adipose tissue offered for joint or other concerns, are not FDA-approved, and the FDA has warned the public about unapproved stem cell products.
How it’s traditionally been approached
Fat tissue has long been used in surgical and reconstructive settings, where surgeons may move a person's own fat from one area to another. That long history is different from the newer practice of processing fat and placing it elsewhere with the goal of supporting a joint or tissue.
In orthopedic and regenerative medicine settings, some clinicians have explored MFAT in connection with joint discomfort, such as in the knee. The evidence for these uses is limited or investigational, and results from one setting cannot be assumed for another person.
Because the practice is still being studied, approaches differ from clinic to clinic, including how tissue is collected, processed and placed. Whether any approach is appropriate is a decision for a licensed clinician after an evaluation, and not something a web page can determine.
How the right provider may help
The right provider may help you sort through what is established, what is investigational and what is simply marketing. A visit generally begins with a conversation about your health history, your concerns, what you have already tried and what you hope to understand.
A thoughtful clinician may also review conventional options and alternatives with you, explain the possible risks, and tell you plainly whether a given procedure is FDA-approved, being studied under a registered trial, or not approved. There is no guarantee any approach will help, and a good provider will say so.
Useful questions to ask: Is this product or procedure FDA-approved for my condition? Is it part of a study registered on ClinicalTrials.gov with IRB oversight? Is your license current with the state medical board? What are the risks and alternatives, and will I receive them in writing as part of informed consent? You may also want to ask what happens if it does not help.
The whole-person view
Body, mind and stress affect each other. Ongoing pain or limited movement can influence mood, sleep and confidence, and stress can in turn change how the body feels. Looking at the whole person, rather than one joint or one tissue, can give a fuller picture.
Some people find body-based support, such as the approaches offered through Somatic Experiences, helpful for building awareness of how stress shows up physically. Others value talking through worry, frustration or decision-making with a counselor, such as through Therapists.plus. These are complementary supports and do not replace care from a licensed clinician.

Keep in mind
- Most clinic-offered adipose, SVF, MSC, umbilical cord and exosome products are not FDA-approved, and the FDA has warned the public about unapproved stem cell and exosome products. No exosome product is FDA-approved.
- Verify the product's FDA status, confirm any study is registered on ClinicalTrials.gov with IRB oversight, check the clinician's license with the state medical board, and get written informed consent covering risks and alternatives.
- Watch for red flags: cure-all or 'treats everything' claims, paying to join a 'clinical trial', testimonials offered in place of evidence, and pressure to travel abroad or across states for treatment. 'Holistic' or 'alternative' framing does not change FDA status.
- Licensed professionals should guide care for any serious condition. For emergencies call 911; in a crisis call or text 988.

Frequently asked questions
What is microfragmented adipose tissue?
Microfragmented adipose tissue (MFAT) is a person's own fat tissue that has been collected and processed into smaller fragments. It keeps some of the natural structure of fat and is discussed in regenerative medicine and stem cell therapy conversations. Its use for most conditions is considered limited or investigational.
Is microfragmented adipose tissue FDA-approved?
No, microfragmented adipose tissue is not FDA-approved as a stem cell therapy for treating joint or other conditions. In the U.S., the only FDA-approved stem-cell products are cord-blood-derived HPC products for certain blood and immune disorders. Ask any provider to explain the regulatory status of what they offer.
Is microfragmented adipose tissue the same as stem cell therapy?
Not exactly. MFAT is processed fat tissue that contains a mix of components, including some cells sometimes called MSCs, and it is often discussed alongside stem cell therapy. It is not the same as FDA-approved HPC transplant products, and the terms are sometimes used loosely in marketing.
What is the difference between MFAT and SVF?
MFAT keeps fat in small fragments with much of its natural structure, while stromal vascular fraction (SVF) generally refers to a cell mix separated from fat tissue. Both are adipose-derived approaches, and most clinic uses of either are not FDA-approved. A licensed provider can explain how a specific clinic describes its process.
Does microfragmented adipose tissue regrow cartilage or avoid surgery?
There is no reliable basis to claim that microfragmented adipose tissue regrows cartilage or avoids surgery. Evidence is limited and investigational, and individual results vary. Be cautious of any clinic that promises these outcomes.
How do I find a trustworthy provider to ask about microfragmented adipose tissue?
Start with a licensed clinician and confirm their license with your state medical board. Ask whether the procedure is FDA-approved, whether any study is registered on ClinicalTrials.gov with IRB oversight, and request written informed consent covering risks and alternatives. Directories like Providers.plus list licensed providers you can research.
