What is PRP?

PRP stands for platelet-rich plasma and refers to an emerging non-surgical medical procedure whereby a patient’s own blood is processed to increase the concentration of platelets. Platelets are a naturally occurring cell in your blood, along with white blood cells, red blood cells and plasma.  Platelets primary function is to control bleeding by creating a blood clot. However, they also release growth factors and proteins that can assist with healing and controlling inflammation. The platelet-rich plasma can then be injected into damaged tendons, ligaments, joints and in some cases nerves to improve pain and function.

The premise of this treatment option is that if you boost the concentration of platelets, you also boost the body’s natural healing characteristics.

What conditions can PRP treat?

Although this is a relatively new procedure, mounting scientific research is demonstrating the effectiveness of the use of PRP to treat pain and inflammation from mild-moderate osteoarthritis and chronic tendinosis. If your injury or condition is severe or advanced you may require a more comprehensive biologic approach that includes bone marrow or fat derived cells.

Using the research based treatment algorithms developed by the Orthohealing Method, platelet rich plasma therapy has successfully been used to treat pain and inflammation related to the following: 

Common treatment areas include:

  • Shoulder: rotator cuff tendinosis and/or partial tears, osteoarthritis, labral tears, and bicep tendinosis
  • Elbow: tennis elbow, golfer's elbow, chronic pain and osteoarthritis
  • Wrist: carpal tunnel syndrome, wrist instability, tendinosis
  • Hip: osteoarthritis, bursitis, hamstring tendinosis and/or partial tears and gluteus tendinosis
  • Knee: ligament injuries, patellar and quadricep tendinosis, degenerative meniscal tears tears and osteoarthritis
  • Foot / Ankle: plantar fasciitis, chronic ankle sprain/instability, Achilles tendinosis, and osteoarthritis

Many doctors support the use of PRP to treat pain and inflammation due to arthritis and other degenerative joint conditions.

Can PRP injections be combined with ultrasound guidance?

Dr. Dunbar recommends ultrasound-guided PRP injections for two main reasons: accuracy and tendency toward positive outcomes. For an injection to have a chance to be effective, it has to be injected within millimeters of the damaged area. 

When you don't use ultrasound guidance — known as "blind" injections — physicians pick the injection site by feeling and making the best decision for the optimal injection site. If the site is off, the outcome — or success rate — can be lower. When Dr. Dunbar uses ultrasound to guide her to the proper injection site, she can target the PRP injection with great accuracy.

What to Expect 

Platelet rich Plasma (PRP) is made from a sample of your blood which is drawn and processed on the same day. Your blood will be placed in a centrifuge in order to isolate your PRP.  Under ultrasound guidance your PRP will be expertly injected into the damaged joint or tendon. Dr. Dunbar firmly believes that all biologic therapies should be done under ultrasound guidance to ensure accurate placement and to maximize the anti-inflammatory and pain benefits. The first two - three days after your PRP therapy you may experience discomfort and swelling and you will be provided specific post - therapy instructions and guidance on how to manage this discomfort.  Typically you will feel the benefits of your PRP therapy at three - eight weeks, however the anti-inflammatory effects will continue for up to six - nine months after your last treatment.

How should I prepare for a PRP injection?

There are a variety of things you should and shouldn’t do leading up to a PRP injection procedure. Drink plenty of fluids the day before the procedure. You should also avoid taking certain drugs prior to the procedure, including:

  • Corticosteroid drugs for 3 weeks prior
  • Non-steroidal anti-inflammatory drugs such as aspirin or ibuprofen a 2 weeks prior
  • Arthritis medications such as Celebrex for two weeks prior 
  • Anticoagulation drugs for five days before
