Regenerative Medicine
Bone Marrow Aspirate Concentrate (BMAC)
Bone marrow aspirate concentrate (BMAC) is a regenerative medicine treatment that uses concentrated cells from your own bone marrow — including mesenchymal stem cells and growth factors — to promote tissue healing and regeneration in damaged joints, tendons, and other structures.

How It Works
Bone marrow is harvested from the posterior iliac crest (hip bone) using a specialized needle under local anesthesia. The aspirate is processed in a centrifuge to concentrate the regenerative cells and growth factors, then injected into the damaged tissue under imaging guidance.
Treatment day
What to Expect
60-90 minute procedure. The bone marrow harvest involves brief pressure at the hip. The injection into the target area is similar to other image-guided injections. You may experience soreness at both the harvest and injection sites for several days.
Afterward
Recovery
Mild soreness at the harvest site for 1-3 days. Avoid strenuous activity for 2-4 weeks. Gradual return to full activity over 4-8 weeks.
Duration of Relief
Results develop over 3-6 months. Many patients experience sustained improvement lasting 1-2 years or longer.
