Bone Marrow Concentrate (BMAC) Providers

Understanding Bone Marrow Concentrate (BMAC)

Bone marrow is collected, usually from the pelvis, and processed to concentrate a mixed population of cells, platelets, and signaling proteins. BMAC is not the same as a purified or culture-expanded stem cell product, and its composition varies by patient and processing method.

Where It May Fit

BMAC is used most often in orthopedics for selected joint, cartilage, bone, and tendon problems. Research is growing, including studies in knee osteoarthritis, but preparation methods and comparative evidence remain variable. The intended use should be tied to a specific diagnosis and treatment goal.

What to Expect

The procedure generally includes marrow aspiration and image-guided placement at the treatment site. Ask where marrow will be obtained, how it will be processed, what is actually measured in the final product, what rehabilitation is planned, and how outcomes will be tracked.

Questions to Ask a Provider

• What exact product, preparation, dose, and source will be used?
• Why is this treatment being recommended for my diagnosis, and what evidence supports that use?
• What is the product’s regulatory status, who will perform the procedure, and will guidance be used when appropriate?
• What benefits, limitations, alternatives, recovery plan, follow-up, and total costs should I expect?
