What are Platelet-rich plasma (PRP) injections?

Platelet-rich plasma (PRP) injections have emerged as a favorable treatment in various medical fields, offering a natural and minimally invasive approach to tissue repair and regeneration. Derived from a patient’s blood, PRP contains a concentrated amount of platelets and growth factors that play a crucial role in the body’s healing process. This innovative therapy has gained considerable attention for its potential to accelerate healing and alleviate symptoms in conditions ranging from orthopedic injuries to skin care and hair restoration.

What are PRP Injections?

Platelet-rich plasma (PRP) injections are a treatment to help cure an injury. Based on your blood, these shots are better used to treat sports injuries and support wounds healing after surgery. Some doctors use it as a cosmetic approach to mark signs of aging, such as wrinkles. 

Plasma is the liquid part of your blood, especially water and protein. It allows red and white blood cells and platelets to move through your bloodstream. Platelets are blood cells that create blood clots. They also play a part in healing.

What does platelet-rich plasma (PRP) do?

PRP products are usually given as injections (shots) to recover and fix injuries. The position of platelets in the body is to allow blood clots when there is an injury. Platelets’ cytokines and growth factors can help improve damage and encourage healing. 

Studies have indicated that PRP is or may help treat:

  • Tennis elbow 
  • Knee osteoarthritis 
  • Sports injuries 
  • Wounds.
  • Hair loss.

Do Platelet-rich plasma (PRP) injections Work?

More investigations are required to see what conditions PRP might work on. Some studies reveal that it speeds healing after injury or surgery for specific needs. Along with helping injured tissue heal, some studies show PRP injections curb pain, boost mobility for people with rotator cuff injuries, and relieve symptoms in arthritic shoulders. Early research shows it might be effective in some instances of low back pain.

But the information to date is mixed. When researchers looked at more than 20,000 PRP injections over ten years, they needed clarification on whether the results justified the cost. A series of clinical studies 2021 found that PRP injections worked no better than a placebo for people with osteoarthritis of the ankle or knee or for Achilles tendinitis.

PRP injections decrease hair loss in people with male or female baldness. But it’s unclear whether facial PRP injections lessen signs of aging, like wrinkles and sagging skin.

It may take several weeks for PRP injections to produce noticeable results. In some instances, specifically those affecting the hair or skin, the full effects may take up to six months to become visible. In certain situations, such as with hair loss, it may be necessary to repeat the procedure to maintain the results.

Preparing for PRP Injections

Before getting PRP injections, you should stop taking certain medications that thin your blood, like aspirin and ibuprofen. You may also need to take a break from specific vitamins or supplements, such as omega-3 fatty acids. Your doctor can tell you precisely how to prepare for these shots.

Do PRP injections have side effects or risks?

PRP doesn’t usually cause significant side effects. But because it involves drawing blood – if your doctor recommends it – you’ll want to ensure you eat before the procedure. Adherence to these guidelines is advised to prevent dizziness after receiving PRP injections. Do not wash the treated area for 48 hours after the shot. You may encounter some soreness and bruising in the injected area. You must inform your doctor immediately if you experience sharp or intense pain.

Because you’re being treated with your blood, the risk of allergic reaction is low. Complications you might have include: 

  • Bleeding 
  • Damaged tissue 
  • Nerve injury 
  • Infection 

You can’t obtain PRP injections if you hold:

  • Anemia
  • Cancer
  • An infection

It would help if you only got PRP injections from a licensed doctor.

PRP Injection Procedure 

A doctor draws blood from your body to collect plasma and uses a centrifuge to separate the platelet-rich plasma from the rest of the blood. Then, the doctor applies a numbing agent to the area of your body, receiving PRP injections. Once you’re numb, the doctor uses a needle to inject your plasma into the size of your body being treated.

If you’re receiving treatment for a muscle injury, your doctor may inject plasma into multiple areas of the affected muscle. Doctors sometimes use ultrasound technology during the shots to ensure they’re targeting the right place. PRP injections usually take about 30 minutes, depending on your target area.

Platelets release growth factors that help renew cells in treated areas. This is thought to trigger your body’s healing process.

Final words 

Platelet-rich plasma (PRP) injections have emerged as a promising therapeutic approach in various medical fields due to their potential to accelerate healing and tissue regeneration. These injections harness the body’s natural healing mechanisms by concentrating platelets and growth factors from the patient’s blood, promoting tissue repair and regeneration. 

While research continues to explore its effectiveness across conditions such as sports injuries, osteoarthritis, and dermatological issues, PRP injections show encouraging results, offering a minimally invasive option with relatively low risk and the potential for enhancing recovery and alleviating symptoms in various medical contexts. 

However, further studies are warranted to optimize protocols, standardize procedures, and ascertain their long-term efficacy in diverse clinical settings.
