Regenerative Therapy: Frequently Asked Questions

Platelet Rich Plasma (PRP) and stem cell therapies are regenerative medicine therapies that provide potentially effective alternatives to surgery and other pain treatment methods.  Most procedures are performed in less than an hour with very little post recovery. Many patients are able to return to their normal activities the next day.

Following are frequently asked questions about the regenerative therapies offered at Greenwich Hospital.

Platelet Rich Therapy

What is Platelet Rich Plasma?

Platelet Rich Plasma is a concentrated form of blood rich in platelets and growth factors that stimulate healing and regeneration of injured tissues, muscles, tendons or ligaments. PRP is derived from your own body and is 100% natural. PRP injections are an effective and safe nonsurgical therapy to treat forms of acute and chronic pain.

What conditions are treated with Platelet Rich Plasma?

Platelet rich plasma therapy procedures can treat a wide variety of conditions including but not limited to: 
  • Back and neck pain 
  • Tennis and golfer’s elbow 
  • Arthritis of the joints with joint-related pain
  • Rotator cuff injuries 
  • Ligament, cartilage and tendon injuries 

Where does Platelet Rich Plasma come from?

To produce platelet rich plasma, a small sample of your blood is drawn into a special collecting device. This blood is centrifuged at high speed to isolate the growth factors and platelets. Because your own blood is used, there is no risk of a transmissible infection, and a low risk of allergic reaction.

What is Platelet Rich Plasma therapy?

First, platelet rich plasma is produced using a small amount of your own blood. This PRP is carefully injected into your affected site by a board certified physician with expertise in minimally invasive procedures and additional training in regenerative injection techniques.

What should I expect from Platelet Rich Plasma treatment?

Platelet rich plasma therapy is a safe, non-surgical procedure that stimulates healing and treats acute and chronic pain. Although your own response will depend on your particular condition, patients generally see improvement in pain and mobility within 4 to 6 weeks. Improvement may continue for up to 12 months.

What does Platelet Rich Plasma therapy cost?

The cost of a platelet rich plasma treatment varies based on your specific treatment needs.

Stem Cell Therapy

What are stem cells?

Stem cells are the body’s master cells. They have the ability to transform – in a process called differentiation — into a variety of different cells, replace dying cells, and regenerate damaged tissue. 

Stem cells are derived from your own body’s bone marrow or fat deposit (adipose).

An alternative method for regenerative medicine is through allograft tissues (from a purified amniotic source). These tissues have a high concentration of collagens, structural proteins and growth factors that support healing and can have some advantages over other regenerative therapies.

What is stem cell therapy?

Stem cell therapy is a simple and safe outpatient procedure when performed by a qualified physician. 

First, your own bone marrow or fat tissue is collected.  Once a sample of your bone marrow or fat tissue has been obtained, the cells are isolated with a specialized centrifuge.  (If amniotic stem cells are used, they are delivered to the doctor’s office ready for injection.)  The stem cells are then carefully injected into the site where the injury exists and the healing and regeneration begins.

What is the recovery time for stem cell injections?

Stem cell injections are performed as an outpatient procedure.  Most patients return to their normal routines the day after the procedure. Healing occurs gradually over 2 to 6 weeks and can continue for 12 months or longer.

What does stem cell therapy cost?

The cost of stem cell treatment varies based on your specific treatment needs.
