Bone Marrow Aspirate Concentrate (BMAC)
What is Bone Marrow Aspirate Concentrate?
Bone marrow aspirate concentrate (BMAC) is a regenerative treatment derived from bone marrow, specifically targeting mesenchymal stem cells. These cells have the unique ability to differentiate into various musculoskeletal tissues such as tendons, ligaments, and articular cartilage. BMAC is most commonly harvested from the iliac crest of the pelvic bone by inserting a needle into the marrow space and extracting the concentrate.
This therapy may be appropriate for individuals experiencing chronic joint pain who are seeking to enhance their quality of life while potentially avoiding invasive surgical interventions and their associated risks.
What Conditions Can Be Treated with BMAC?
- Tendon injuries & tears
- Ligament injuries & tears
- Cartilage damage
- Tendinitis (inflammation of the tendons)
- Tendinosis (wear of the tendons)
How Do You Prepare for BMAC Therapy?
Preparation for BMAC therapy is typically straightforward. However, it is important to stop taking any non-steroidal anti-inflammatory drugs (NSAIDs) at least two weeks prior to the procedure, as these medications can interfere with the body's natural healing response. Your physician will provide personalized instructions based on your medical history and the condition being treated.
The BMAC Procedure
- The procedure begins with the collection of bone marrow from your own body, typically from the posterior hip area (iliac crest). The skin is sterilized and a local anesthetic is applied to numb the area. A specialized needle is then inserted into the bone, and bone marrow is aspirated using a syringe.
- This sample is then processed using a centrifuge, which spins the aspirate for approximately 10–15 minutes to separate and concentrate the regenerative cells from the other blood components.
- Next, the area of injury is cleaned and numbed. Using imaging, the concentrated BMAC is precisely injected into the damaged tissue. The entire procedure is typically completed in under one hour, and most patients are able to return home the same day.
Post-Procedure Care
- Most individuals can return to work or light activity as early as the next day following the injection. However, it is important to avoid weight-bearing or strenuous activities for at least two weeks to allow optimal healing.
- NSAIDs should continue to be avoided after the procedure, as they may inhibit the regenerative effects of the treatment. Your provider may recommend alternative pain relief options if necessary.
