Platelet Rich Plasma Injections

What is Platelet Rich Plasma?

Platelet Rich Plasma (PRP) is a specially prepared sample of your blood in which all of the red and white blood cells (RBCs and WBCs) have been removed and the platelets are concentrated by spinning the sample in a specially designed centrifuge device.

How Does Platelet Rich Plasma Work?

A syringe of your blood is drawn and placed in a machine called a centrifuge, which spins the blood to separate the platelets from the other blood components. Platelets are the cells that circulate in your blood and will immediately identify and stick to any injured area in a blood vessel. They then create an immediate seal wherever there is a disruption of the vessel, and release proteins that start the tissue regeneration and healing. PRP can be used to promote healing in any area requiring a “jump start” in the body’s ability to heal injuries. The concentrated platelets are injected into the injured area where they release the proteins that start the bodies’ natural healing process. The platelet concentrate is injected directly into the involved tissues. The platelets then become “activated” in that area and help your body to begin the healing process. Sometimes other “boosters” such as Stem Cells or Growth Factors can be mixed with the PRP for an even more robust response.


It is important to know that all “PRP” is not the same. There are different ways of collecting and processing the cells which can result in a wide range of end products—and some definitely work better than others. Dr. Greenberg uses a method that has been refined and extensively studied, and has had an excellent track record for many conditions. Also, keep in mind that the technique for placing the PRP is crucial. Dr. Greenberg uses direct real-time visualization of the injections either under Ultrasound or Fluoroscopy X-ray to get the best results with every injection.

What Should I Expect from Platelet Rich Plasma Treatment?

You should come to the procedure well rested and well hydrated. If you take any blood thinners or anti-inflammatory medications, be sure to discuss with Dr. Greenberg in advance whether these should be withheld for a period of time before the injection. Similar to other RIT treatments, such as Prolotherapy, it may take as long as a month to feel results of the procedure. You may experience pain after the procedure the first 48 hours – this is the inflammatory phase. It is safe to apply ice or take Tylenol as instructed. It will then be necessary to evaluate your body’s response to the procedure to determine if repeat treatments are required for more complete relief.
