What Is Platelet Rich Plasma (PRP) Therapy? (Benefits and Uses)

May 23rd, 2016 | 2 min. read

By Rob S Williams, MD



If you follow professional sports, you may have heard about platelet rich plasma therapy, or PRP — a therapy credited by many world-class athletes for accelerating the repair of their sports injuries. Today, more and more orthopedists are offering PRP injections to help treat non-pro sports injuries and arthritis — but what exactly is PRP, and is it right for you? 

Platelet rich plasma therapy (PRP) is a sports medicine treatment that emerged in the 1980s and gained popularity in the last 20 years because of its use by high-profile athletes like Tiger Woods and Kobe Bryant.

PRP therapy is, essentially, the preparation of an enriched supply of a patient's own blood, which can be injected at the site of an injury to help promote faster healing of chronic tissue injuries like tendinitis, sprains, and some milder forms of arthritis.

How PRP Works

Platelets (also called thrombocytes) are components of our blood (plasma) that contain proteins called growth factors. These growth factors play an important role in signaling the body to heal itself through clotting, controlling inflammation, and building and healing tissue and skin.

PRP therapy focuses on delivering more growth factors to the site of an injury in order to trigger this healing. It involves the preparation of an enriched supply of a patient's own platelets. This platelet enriched plasma (PRP) contains five to 10 times the normal concentration of platelets.

Once prepared, PRP is injected to the site of the injury to help reduce inflammation and promote faster healing.


In some cases, patients who receive PRP treatment may be able to postpone or avoid joint replacement surgery or other invasive procedures like knee arthroscopy, total knee replacement, or tennis elbow surgery.

PRP therapy can be a helpful healing alternative for patients who do not want or cannot have open or arthroscopic surgery. 

PRP therapy can be performed in an orthopedist's office and involves the following:

  1. Your orthopedist will draw your blood.

  2. Using a centrifuge, platelets will be separated from other blood cells (red and white cells). This centrifugation increases the concentration of platelets to 5 or 10 times their normal concentration.

  3. The increased concentration of platelets is extracted with the plasma.

  4. The resulting PRP preparation is injected to the site of your injury (for example, your knee or elbow).

The platelets and other growth factors then begin to do their work, signaling your body to stimulate cell growth and cell repair at the injury site.

Benefits of Platelet Rich Plasma (PRP) therapy

PRP therapy has several benefits:

  • For some, it can be a non-invasive alternative to surgery. 

  • It uses your own plasma to help stimulate and accelerate your body's natural healing process.

  • It's low risk — no more dangerous than a collagen injection.

  • It supports long-term healing of your injury, rather than quick, temporary relief from your symptoms.


uses OF PRP therapy

Platelet rich plasma injection therapy has been used to help support the healing of:

  • mild to moderate arthritis, especially in the knee

  • chronic tendon injuries, like Achilles tendinitis or tennis elbow

  • acute tissue injuries, like ligament or muscle pulls, tears, or sprains

Depending on the extent of your injury, you may need just one PRP therapy injection or your doctor may recommend several. You can expect to return to normal activities and sports within a few days to a few weeks.

PRP therapy may also be used during some orthopedic surgeries to help promote faster healing.
