Platelet-rich plasma, or PRP, has received a lot of attention in the treatment of injuries—especially with well-known athletes like Tiger Woods and Maria Sharapova. But is it safe, effective, and does it work? Let’s address some of the frequently asked questions about PRP.

What is Platelet-Rich Plasma?

To understand PRP, it’s important to understand blood. Our blood consists of mostly liquid, called plasma. Plasma is the clear liquid portion of blood that remains after red blood cells, white blood cells, platelets, and other cellular components are removed.

Platelets contain lots of enzymes, proteins and growth factors that can kick-start your normal healing process to encourage your body to heal itself. And Platelet Rich Plasma (PRP) is plasma with more platelets that what is typically found in your blood—sometimes 5 or 10 times greater than usual.  This increased number of platelets acts to increase the healing potential at the site where the PRP is injected.

How It Works

A PRP injection starts with blood being drawn from the patient. The platelets are separated and concentrated from the rest of the white and red blood cells using centrifuge. And finally, the highly concentrated platelets is then injected into the area of treatment to promote tissue healing.

Does it Work?

There are a lot of testimonials regarding how great PRP works for orthopedic injuries.  I am sure if you watch sports channels, you have heard a number of athletes and coaches touting the benefits of PRP and return to play. More research is being published each month on the efficacy of PRP in orthopedic and spine injuries. Most of the published reports on the use of PRP show promise as measured by decreased pain and improve function extending for many months.

What does the research say?

One study, showed PRP treatment as more effective than a placebo for knee osteoarthritis. Another systemic review of randomized controlled trials of PRP for knee osteoarthritis also showed “significant” reductions in arthritic pain.

In another study, PRP treatment into the low back disc showed improved function and decreased pain scores. For SI joint pain ( avery common cause of low back pain), a case series using PRP also showed improved function and decreased pain scores that extended at least to a year.

Researchers are trying PRP treatment for applications that tendon injuries, hair loss, acute injuries (e.g. pulled hamstrings), and postsurgical repair.  More research continues to be done to show the efficacy of PRP.

Is PRP safe?

PRP has been shown to be safe as it uses the patient’s own blood.

Should I use PRP treatment for my injury?

For active individuals and amateur athletes, changes to diet, workouts, and ample recovery are the first steps to a healthy self.   If this is not working, the next step is to consult your physician to receive an accurate diagnosis and treatment that may include regenerative medicine options such as PRP.
