What Are Plasma Rich Protein Injections?

A quickly emerging medical breakthrough, plasma rich protein injections are becoming popular not only among elite professional athletes, but among the general population. Plasma rich protein injections are also known as:

  • Platelet rich protein injections
  • PRP injections
  • Plasma rich protein therapy
  • PRP treatments

According to an article in the New York Times, sports medicine experts have high hopes for this therapy. Should it prove to have the results it has shown early signs toward, it could be instrumental in aiding in the pain relief of persistent injuries such as tendinitis of the knee and tennis elbow for both the professional and recreational athlete. Famous athletes such as Tiger Woods have touted the efficacy of this groundbreaking procedure, calling quite a bit of attention to it in the media.

Types of Plasma Rich Protein Injections

Most commonly known as platelet rich plasma therapy, or PRP therapy, this injection uses the patient’s own blood to help heal their injuries. Since it is autologous, meaning it comes from the patient’s own body, there is very low risk for transmissible infection or allergic reaction. Additionally, early research has shown such positive results that it may be a way to avoid surgery and a lengthy recovery.

A PRP therapy procedure is fairly simple. A small sample of blood is taken, and then placed into a machine that creates a centrifuge, separating the platelets or plasma from red blood cells. Once this process is completed, a concentration of ten times the normal amount of platelets is left, leaving super-concentrated platelets rich in healing properties. These concentrated platelets are then injected into the injured area, promoting healing and regeneration of injured tissue.

OrthoNC.com reports the following about PRP therapy results:

“You will feel a notable increase in pain in the days immediately following the injection. Pain intensity becomes less each day as functional mobility and general functional ability increase along with endurance and strength. You will notice gradual improvement 2-6 weeks after PRP therapy. Some patients report ongoing improvement 6-9 months after PRP therapy is administered.”

Conditions Related to Plasma Rich Protein Injections

When the body sustains soft tissue injury, platelets go to the site of injury and begin to regenerate and heal. However, some areas of the body receive a poor blood supply, thus making it difficult for the body to repair any tears or internal scarring.

One such example would be tendinitis or rupture of the Achilles or tendonitis of the knee or elbow. It is now thought that because of the low blood supply, these areas of the body can never fully heal. With the advent of plasma rich protein injections, this problem may become a thing of the past.
