How BMAC injection works
from marrow to treatment site

BMAC therapy uses your own bone marrow aspirate, concentrated to increase the cellular and growth-factor components delivered to the affected area.

Bone marrow is aspirated under sterile, controlled conditions.
The sample is processed to concentrate regenerative components.
Prepared BMAC is injected with targeted image guidance.

This approach aims to reduce inflammation, improve function, and support tissue repair while avoiding more invasive surgery in selected cases.
