Platelet-Rich Plasma (PRP) Injection

What is Platelet-Rich Plasma (PRP)?

Our blood consists of a liquid component known as plasma. It also consists of three main solid components which include the red blood cells (RBCs), white blood cells (WBCs), and platelets. Platelets play an important role in forming blood clots. They also consist of special proteins, known as growth factors, which help with our body’s healing process. Platelet-rich plasma or PRP is a high concentration of platelets and plasma. A normal blood specimen contains only 6% platelets, while platelet-rich plasma contains 94% of platelets and 5 to 10 times the concentration of growth factors found in normal blood, thus greater healing properties.

What are the indications for PRP Injections?

PRP is a relatively new method of treatment for several orthopedic conditions such as muscle, ligament, and tendon injuries; arthritis; and fractures. PRP injections can help alleviate painful symptoms, promote healing, and delay joint replacement surgeries.

Who is a candidate for a PRP injection?

Consultation with Dr. Walker is essential to determine if you are a candidate, so he can properly discuss with you the risks and benefits of this treatment option. If you are a candidate for a PRP injection, our office can schedule a follow up appointment in the clinic to proceed with the procedure.

How do you prepare for a PRP injection?

Patients must stop use of any form of anti-inflammatories (NSAIDs) such as Aleve, Advil or Ibuprofen two weeks prior and two weeks after a PRP injection. Concomitant use of NSAIDs can potentially decrease the efficiency of the PRP injection.

Platelet-Rich Plasma Injection Procedure

Your doctor will first draw about 10 cc’s of blood from the large vein in your elbow. The blood is then spun in a centrifuge machine for about 10 to 15 minutes to separate the platelets from the remaining blood components. The injured part of your body is then anesthetized with a local anesthetic. The platelet-rich portion of your blood is then injected into your affected area. In some cases, your doctor may use ultrasound guidance for proper needle placement.

Post-Procedure Care following PRP Injections

After the injection, your affected joint and/or body part will be bandaged, which can be removed at the end of the day. Common side effects reported after a PRP injection include swelling, bruising or bleeding, and pain. You can use over-the-counter Acetaminophen to help alleviate pain. To ensure the best results from a PRP injection, please refrain from any strenuous activity and/or exercise to the affected extremity in the 1-2 weeks following your PRP injection.

Dr. Walker will have you return to clinic in 6 weeks to assess how you’re feeling after the PRP injection and determine if you are a candidate for an additional PRP injection.

Risks and Complications of PRP Injections

There are very minimal risks associated with PRP injections. Some of the potential risks include:

• Increased pain at the injection site
• Infection
• Damage to adjacent nerves or tissues
• Formation of scar tissue
• Calcification at the injection site

If you have any questions, please call Dr. Walker’s office or send a message through the patient portal.
