⚡ Quick Summary: What is MFAT?
If you are experiencing moderate to severe joint pain, advanced joint degeneration, or complex soft tissue injuries, here is the summary:
- What it is: A treatment that uses a tiny amount of your own body fat to support and repair damaged joints.
- How it works: Fat tissue is rich in regenerative cells, including mesenchymal stem cells and growth factors. We gently collect it, refine it, and inject it precisely into the affected area.
- The “Cushion” Analogy: Think of a worn-out joint like a shoe that has lost its padding. MFAT acts like a new, high-tech cushion that supports the joint and helps it move smoothly again.
- The ROSM Difference: We use an FDA-cleared device to ensure your cells stay healthy and powerful, combined with real-time ultrasound guidance for every injection.
Bridging the “Treatment Gap”
Many patients dealing with joint degeneration and chronic pain are told to wait and see until they are ready for a total joint replacement. At ROSM, we believe waiting for your body to get worse is not a plan. MFAT fills the gap by providing a structural boost that can delay or even prevent the need for surgery.
What Conditions Can MFAT Help?
- Severe joint degeneration and pain: knee, hip, or shoulder, including cases where cartilage loss has become advanced.
- Complex soft tissue injuries: including rotator cuff and more severe acute or chronic tendon damage.
- Joint instability: ligament sprains that have not healed with traditional therapy.
- Patients seeking a surgical alternative who want to delay or avoid a joint replacement.
A ROSM physician assessing a patient’s joint before recommending MFAT, the first step in confirming this is the right treatment for the injury.
The ROSM Standard: Why Our MFAT is Superior
- The ROSM Advantage: We use an FDA-cleared device to gently micro-fragment your fat tissue without harsh chemicals or enzymes, preserving the regenerative cells so they remain intact and ready to work.
- Minimal Discomfort: The fat collection is gentle and performed under local anesthesia. Most patients describe it as much easier than they expected.
- No “Blind” Shots: Just like our PRP, every MFAT injection is guided by ultrasound, placed exactly where your tissue is most compromised.
The Journey: What to Expect
- Step 1, The Collection: We gently collect a small amount of fat from your abdomen or upper buttock.
- Step 2, The Refinement: We clean and refine the tissue using our FDA-cleared device, removing impurities while keeping the regenerative cells fully active.
- Step 3, The Precision Injection: We use ultrasound guidance to place the MFAT cushion directly into the damaged area.
- Step 4, The Results: You may feel mild soreness at the collection and injection sites for a few days. Most patients begin to notice a quieter, smoother joint over the next 8 to 12 weeks.
Every MFAT injection at ROSM is placed under live ultrasound guidance, so the treatment lands exactly where the joint needs it most.
A note on cost: MFAT is an orthobiologic treatment, and most insurance plans currently classify it as investigational, meaning it is usually paid for out of pocket. HSA or FSA funds can typically be used to cover the cost. Coverage varies by plan, so the clearest way to know where you stand is a quick conversation with our team. Here is why insurance often works this way for regenerative treatments.
