Micro-Fragmented Adipose Tissue (MFAT) Therapy:
Harnessing the Power of Your Own Cells for Regeneration in Portland, Oregon

MFAT Stem Cell Therapy

Why MFAT Therapy?

MFAT Therapy is a treatment that uses stem cells derived from a person's own adipose (fat) tissue to cushion, support, and promote healing. The cells and tissue is collected through a minimally invasive liposuction procedure, where a small amount of fat is removed from the patient's body.

The collected fat is then processed to isolate and concentrate the relevant cells and tissue (known as stromal vascular fraction, or SVF), and then injected into the area of the body that needs treatment. 

MFAT therapy can be used to treat a variety of conditions that cause joint pain and injuries. The procedure is generally considered safe, as it uses the patient's own stem cells, reducing the risk of rejection or other complications.

Stem Cells

Adipose tissue is rich in Mesenchymal Stem Cells which can aid in repairing and slowing the breakdown of tissue like cartilage and tendon. 

The Stem Cells do this not only through the ability to morph into various cell types but also by sending out healing signals to the surrounding area that reduces inflammation and builds healthy tissue, in a wide array of areas and conditions.

From Your Own Body
Using the stem cells from your own body ensures viability and greatly reduces the risk of adverse events. Age, sex, ethnicity, and BMI do not strongly effect one's candidacy for MFAT therapy. We all have Stem Cells in our body that can be readily used to aide in healing. The most important factor is the severity of the condition and this will be discussed thoroughly between you and Dr. Oltman prior to any treatment. 

Long Lasting Relief

For most patients, the biggest upside of MFAT is that a single treatment can work to relieve pain for years. Most studies (see below) on MFAT track patient progress over a 3-5 year span, seeing benefit all the way through. Downtime is required after any treatment so needing only a minimal number of treatments is an enormous advantage of MFAT. PRP is also commonly used in the interim to maintain results for long, multi-year, stretches.

Scientific Evidence

What does the scientific literature show?


How Many Treatments Will I Need?

MFAT therapy is generally done as a "stand-alone" procedure, meaning it is not repeated. The effects of the MFAT therapy are long acting and if a repeat procedure is necessary it's not until 2+ years after the last one, depending on severity. Degenerative conditions, like osteoarthritis, generally get optimal results with routine PRP treatments every 6 months following the MFAT therapy procedure. 

Are The Treatments Painful?

There is often temporary discomfort/pressure associated with the treatment as fluid is placed into small spaces. We offer a full array of options to ensure and prioritize patient comfort:  

  • Local and Regional anesthetic

  • Nerve Blocks when indicated

  • Nitrous Oxide Sedation

  • Pain Medication (Opioids and/or natural supplements)

  • Anxiolytics (Rx or natural supplements)

The majority of patients experience minimal pain with these measures. All patients will be provided instructions for post-treatment care that outlines additional comfort measures.

Is There A Recovery Period After A Treatment? 

For MFAT therapy, the recovery period is usually 5-7 days. During this period the treated area may feel increased achiness and/or stiffness that can be treated with heat applications and Tylenol (not anti-inflammatories). Opioids will also be prescribed for the first few days. You do not need to be immobilized or completely non-weight bearing but you should avoid all strenuous activity during this period. After the post-treatment soreness has resolved you may begin slowly increasing your physical activity as tolerated. 

Are There Medication Restrictions During The Treatment Course?

Most medications do not need to be stopped and do not interfere with the treatments. The exception are anti-inflammatories. This includes NSAIDs (Advil, Aleve, ibuprofen, etc) and steroids (prednisone orally or steroid injections). These inhibit the process that the treatments are trying to stimulate so they should be discontinued prior to any treatment. There are some exceptions and Dr. Oltman will address your specific needs as a part of your treatment plan. 

What Is The Cost Of A Treatment?

We require payment at the time of service. We provide you with a Superbill that you can submit to your insurance company for reimbursement. HSA accounts can also be used to pay for our services.

See our Pricing Page for the full details on treatment cost.

Are The Treatments Image-Guided?

Yes. Every treatment and every injection a patient receives is ultrasound-guided for the highest possible precision. The target is visualized and Dr. Oltman guides the needle directly into the area where the medicine needs to go for maximum results. There is no guess work. Dr. Oltman's RMSK credential is "Registered in Musculoskeletal Ultrasound" and distinguishes him as an expert in the technique that only a few doctors in the entire state of Oregon have.
