Platelet-Rich Plasma (PRP) Injections

Updated: May 16, 2023


Platelet-rich plasma (PRP) injections have gained significant attention in recent years for their potential to treat various medical conditions, including sports injuries, osteoarthritis, and chronic tendonitis. PRP injections involve using a patient's own blood, which is processed to extract the plasma that contains a high concentration of platelets. This plasma is then injected into the affected area, providing a concentrated dose of growth factors to promote healing.

How do PRP injections work?

Platelets are blood cells that play a crucial role in healing and blood clotting. They release growth factors that help to regenerate damaged tissues and blood vessels, and stimulate the body's natural healing response. By concentrating these growth factors and injecting them directly into the affected area, PRP injections aim to accelerate the healing process and reduce pain and inflammation.

What conditions can PRP injections treat?

PRP injections have been used to treat a variety of medical conditions, including:


PRP injections have been shown to reduce pain and improve joint function in people with osteoarthritis, a degenerative joint disease that affects millions of people worldwide.

Sports injuries:

PRP injections can help to speed up the healing process of various sports-related injuries, such as tendonitis, muscle strains, and ligament injuries.

Examples of tissues which can be treated:

  • Shoulder joint, rotator cuff - tendonitis and tearing

  • Knee joint - joint arthritis and meniscus problems

  • Tennis elbow,

  • Foot and ankle tendon problems

  • Achilles tendon

  • Hip bursa

  • Wrist tendons

Chronic tendonitis:

PRP injections have been shown to improve symptoms of chronic tendonitis, a condition that causes pain and inflammation in the tendons.

Hair loss:

PRP injections have been used as a treatment for hair loss, as the growth factors in the plasma may promote hair growth and thickness.

What to expect during a PRP injection procedure?

PRP injections typically involve the following steps:

  1. Blood is drawn from the patient's arm and placed into a centrifuge, which separates the plasma from the other blood components.

  2. The plasma is then collected and concentrated, typically using a second centrifuge.

  3. The concentrated plasma is then injected into the affected area using a needle.

The entire process usually takes around 30-45 minutes, and patients may experience some mild pain or discomfort at the injection site. Most patients can resume their regular activities immediately after the procedure.

Are PRP injections effective?

While there is still ongoing research to determine the full effectiveness of PRP injections, many studies have shown promising results. For example, a systematic review of PRP injections for osteoarthritis found that they were associated with significant improvements in pain, function, and quality of life. Additionally, a review of PRP injections for chronic tendonitis found that they were effective in reducing pain and improving function in the short term.

It is important to note, however, that the effectiveness of PRP injections can vary depending on the individual and the condition being treated. It is always recommended to discuss the potential benefits and risks of PRP injections with a healthcare professional before undergoing the procedure.

In conclusion, PRP injections are a promising treatment option for various medical conditions, offering a non-surgical approach to promote healing and reduce pain and inflammation. While more research is needed to determine their full effectiveness, many patients have reported significant improvements in their symptoms after receiving PRP injections.
