Platelet-Rich Plasma (PRP) Therapy
Platelet-rich plasma (PRP) therapy is a growing treatment gaining popularity in sports science and dermatology.
How does it work?
Platelets are blood cells crucial for wound healing, as they help form clots to stop bleeding and support cell growth.
To prepare a PRP injection, a medical professional will draw a sample of the patient’s blood, which is then placed in a centrifuge. The centrifuge spins the blood at high speeds, separating it into its components, with platelet-rich plasma (PRP) being one of the layers. The PRP is then extracted and prepared for injection.
Research shows that injecting areas with high concentrations of platelets can stimulate tissue growth and promote cellular healing. For example, PRP is sometimes combined with bone graft therapies to enhance tissue repair and may also be used to treat various musculoskeletal, skeletal, or skin conditions.
What are the benefits?
PRP therapy is used to treat a variety of conditions. Some common treatment areas include:
Hair Growth
Injecting PRP into the scalp may help reduce inflammation that contributes to hair loss. A 2015 study found that men receiving PRP treatment experienced increased hair growth and greater density compared to those who did not undergo the treatment. However, this was a small-scale study, and more controlled research is needed to fully evaluate the effectiveness of PRP for hair growth.
Tissue Healing
PRP injections may help promote tissue healing. A 2014 study found that three rounds of PRP injections reduced symptoms in athletes with chronic patellar tendinopathy, a knee injury, with 28 athletes analyzed in the study. A 2018 review also suggested that PRP could reduce pain and improve healing in cases of ligament and tendon damage. However, the authors noted that more research is needed to fully assess its effectiveness.
PRP may also aid in bone healing, though studies on this are inconclusive. A 2021 review pointed out that the lack of standardization in PRP preparation and application could contribute to the inconsistent results.
Inflammation Reduction
PRP therapy may help reduce inflammation in conditions like osteoarthritis (OA) and rheumatoid arthritis (RA), which can cause joint pain and stiffness. However, its use for arthritis treatment remains controversial. Both the American College of Rheumatology (ACR) and the Arthritis Foundation (AF) strongly advise against using PRP for knee or hip OA.
How much does PRP cost?
The cost of a single PRP treatment typically ranges from $500 to $2,500. Additional treatments may be required, which can increase the overall cost. Prices can vary depending on location, medical facility, and the doctor’s expertise. It’s important to note that few insurance plans cover the cost of PRP therapy.
Side Effects
Since PRP uses a person’s own platelets, adverse reactions are rare. However, patients may experience some irritation, pain, or bleeding at the injection site. Most individuals can resume normal activities shortly after the procedure.
