What is Bone Marrow Aspirate Concentrate (BMAC) Treatment?

BMAC is a concentrate of regenerative stem cells obtained from your own bone marrow. Bone marrow is the soft, spongy tissue that is found in the center of bones, including your hip or pelvic bone. Bone marrow is the section of the body where blood is generated. The stem cells from BMAC are specialized cells that are known to replicate themselves into various types of tissues and help to speed up the healing process by boosting the body’s natural healing abilities and promote tissue growth.

Indications for Bone Marrow Aspirate Concentrate (BMAC) Treatment

Some of the indications for BMAC include:

  • Osteoarthritis of the joints
  • Improve wound healing
  • Osteonecrosis (bone death)
  • Improve tendon healing
  • Treat fractures of the bones
  • Delay progression of the disease, such as arthritis
  • Treat cartilage injuries

Preparation for Bone Marrow Aspirate Concentrate (BMAC) Treatment

In general, preparation for BMAC treatment includes the following:

  • A thorough examination by your doctor to check for any medical issues that need to be addressed prior to the procedure.
  • Depending on your medical history, social history, and age, routine blood work and imaging may be ordered for safely conducting the procedure.
  • You will be asked if you have any allergies to medications, anesthesia, or latex.
  • Inform your doctor of any medications, vitamins, or supplements that you may be taking.
  • Eat a balanced diet that is low in fat and high in protein.
  • Drink lots of water for a few days leading up to the treatment.

  • A written consent will be obtained from you after the procedure has been explained in detail.

Procedure for Bone Marrow Aspirate Concentrate (BMAC) Treatment

In general, the BMAC treatment procedure involves the following:

  • The skin over the injection site is sterilized and numbed with a local anesthetic.
  • A suction syringe attached to a long needle is inserted into the back of your hip bone.
  • The bone marrow is suctioned out through a small needle puncture in the bone.
  • The collected bone marrow sample is transferred to the centrifuge for processing.
  • The sample undergoes a thorough processing and bone marrow aspirate concentrate with specialized cells are obtained. 
  • The concentrate is collected into a sterile syringe.
  • The concentrate is then injected into the affected area under ultrasound guidance.
  • The whole procedure takes about 2 hours to complete and you can go home the same day.

The number of BMAC treatments required depends on the degree of the injury and will be decided by your surgeon.
