Plasma (PRP) Injection for Knee: Relieve Pain & Promote Healing

Blood consists of red blood cells, white blood cells, platelets, and a liquid component known as plasma. Platelet-rich plasma, or PRP, is a high concentration of platelets and plasma, containing 94% platelets, and five-to-ten times the concentration of growth factors found in normal blood, providing greater healing properties.

What Is PRP Injection?

PRP Injection, or plasma injection, is a treatment for several orthopedic conditions, including: muscle, ligament, and tendon injuries; arthritis; and fractures.

PRP injections can help alleviate painful symptoms, promote healing, and delay joint replacement surgeries.

How Is PRP Injection Performed?

The orthopedic surgeon performs PRP Injection according to the following procedure:

  • The surgeon draws approximately 10 cc’s of blood from the large vein in the elbow.
  • The blood is spun in a centrifuge machine for 10 to 15 minutes to separate the platelets from the remaining blood components.
  • The surgeon injects the platelet-rich portion of your blood into your affected area, oftentimes using ultrasound guidance for proper needle placement.

What Happens After PRP Injection Surgery?

Following PRP Injection, it is normal to feel some discomfort at the injection site for a few days after the procedure. The patient will be prescribed pain medications, and instructed on using cold compresses and anti-inflammatory medications to alleviate symptoms. The patient will be able to resume normal activities, but should avoid any strenuous activities, such as heavy lifting or exercise.

What Are the Risks and Complications of PRP Injection?

Compared to more invasive procedures, there are minimal risks associated with PRP injections. Some of the potential risks include pain at the injection site, infection, scar tissues or calcification at the injection site, and damage to nerves or surrounding tissues.
