“I was able to move around more freely, I had less pain with short jogs and no lingering effects.”

“I had constant pain and inflammation with any strenuous activity and with some daily activities such as stairs, kneeling, squatting, etc. It interfered with everyday life. I was constantly taking NSAIDs, icing and had hyaluronic acid injections. The [PRP] procedure itself was relatively painless – some discomfort with the injection. The first 24-48 hours were painful but it quickly improved after that and I was normal in 7-8 days. [The PRP procedure] was absolutely worth it, though I am eager to see further improvements and how long it lasts.”

“I’m 44 years old. 4 weeks ago I tore my calf muscle while skiing on Mt. Hood.”

“I could barely walk the first week after my injury. I had a trip planned to Park City just 4 weeks after my injury and I was intent on being able to ski (I had already purchased my epic pass). Dr. Shipley suggested a PRP/PPP injection in combination with physical therapy. Even one week ago I wasn’t sure it was possible, as I was still having difficulty with my regular exercises. Today I finished day 3 of skiing all over Park City resort, including off-piste and easy black diamonds.”

Carmel, age 44

Orthopaedic Surgery Q&A

Frequently Asked Questions

What is BMAC and how is it different from PRP?

BMAC (bone marrow aspirate concentrate) is drawn from the patient’s own bone marrow, typically at the hip, and concentrated to isolate mesenchymal stem cells and growth factors. PRP is derived from blood. BMAC is generally positioned for more advanced cases or patients who need a stronger regenerative signal than PRP provides.

Does BMAC work better than PRP?

Evidence is mixed. Some studies show BMAC outperforming PRP and hyaluronic acid for pain and function, particularly in more advanced arthritis, but the overall evidence base for BMAC is smaller and less standardized than PRP’s. Preparation protocol and cell concentration significantly affect outcomes, similar to PRP.

Is the BMAC procedure painful?

The bone marrow draw involves brief discomfort during aspiration, typically from the pelvic bone (iliac crest). Light IV sedation, as used in F2 Ortho’s OR based BMAC procedures, meaningfully reduces procedural pain compared to local anesthesia alone.

How long does BMAC take to show results?

Clinical studies generally show meaningful pain and function improvement by 6 to 8 weeks, with continued improvement through 6 to 12 months in appropriately selected patients. Results are not immediate.

Is BMAC FDA approved?

BMAC is an autologous, minimally manipulated tissue procedure regulated under FDA’s same day, same surgical procedure exception (21 CFR 1271), not an FDA approved drug or device. It is a legal, regulated procedure but not “FDA approved” in the way that phrase is typically used for a drug.
