New TechnologiesAdult Stem Cells for the
Treatment of Pain

Stem cells are already present within your body to help regenerate your tissues and induce healing when an injury occurs. But as we get older, we produce fewer stem cells and as a result, less effective healing. Scientists and physicians have made tremendous advances to make cellular therapy and tissue regeneration a reality in treating many diseases.

We Offer Innovative Nonoperative Biologic Treatments

Hyaluronic Acid Injections

Hyaluronic Acid Injections

Hyaluronic acid is a naturally occurring substance in the body that provides lubrication to the joints. In arthritis there is a depletion of hyaluronic acid resulting in joint pain. The injection of hyaluronic acid, also called viscosupplementation, is a therapeutic treatment used to relieve joint pain by restoring the joint environment.

Platelet-Rich Plasma (PRP) Injections

Platelet-rich plasma or PRP is a high concentration of platelets and plasma that is obtained by processing a sample of your blood to improve its regenerative and healing properties. PRP injections can help alleviate painful symptoms and promote healing in cases of muscle, ligament, and tendon injuries; arthritis; and fractures.

Bone Marrow Aspirate Concentrate Injections

Bone Marrow Aspirate Concentrate Injections

BMAC is a concentration of regenerative stem cells obtained from the bone marrow where blood cells are generated. It is usually aspirated from the pelvic bone and when injected into injured tissue the specialized stem cells replicate to cause regeneration of tissues and speed up the healing process.

He kept me super informed on what happened to my knee and how he wanted to go about it and what recovery looked like. I have not had any knee issues since my surgery ...

  • I found Dr. Greenbaum to be very thorough and I didn't feel like I was being pushed through a patient factory like many of the larger ortho groups in the area. He took lots of time to explain things to me and review x rays on which he saw something two previous orthos missed. I found his front offi...
