Regenerative Medicine: PRP - Platelet Rich Plasma/Prolotherapy

Address: 1470 N. 16th Ave, Yakima, WA 98902 Map this address

Regenerative medicine is a rapidly expanding field of medicine (especially in musculoskeletal medicine) that relies on using the body’s innate healing mechanisms to resolve injuries. Currently this is done by injecting either Prolotherapy, PRP, or Stem Cells* into the area of concern.

Why Does PRP Work?

Platelets are a specialized type of blood cell. Blood is made up of 93% red cells (RBCs), 6% Platelets, 1% white blood cells (WBCs), and plasma.

Most people associate platelets with clot formation. While that certainly is an important function of platelets, they are also very much involved in injury healing. Human platelets are naturally extremely rich in connective tissue growth factors.

Injecting these growth factors into damaged ligaments, tendons, and joints stimulates a natural repair process. But in order to benefit from these natural healing proteins, the platelets must first be concentrated. In other words, PRP recreates and stimulates the body’s natural healing process.

In the case of Prolotherapy a hypertonic solution of Dextrose is given in order to cause an inflammatory response and induce the body to produce the natural healing response at the area of injection.

Corticosteroid or “cortisone” injections, as they are commonly referred to, cannot be injected into weight bearing tendons such as the patellar tendon of the knee and Achilles tendon of the ankle because then can weaken the tendon and cause it to rupture. PRP can safely be used in these tendons without the risk of rupture.

How is PRP Done?

In the office, blood is drawn from the patient (just like getting a blood test) and placed in a special centrifuge. The centrifuge separates the RBCs, and the remaining platelets and plasma are then highly concentrated. (The WBCs, which comprise only a fraction of the total cells, go along for the ride with the platelets and plasma.) The red blood cells are discarded, and the resulting platelet concentrate is used for treatment.

In most cases the injections are given under direct ultrasound guidance to insure accurate placement of the platelet concentrate in the damaged area. The entire treatment, from blood draw, to solution preparation, to injection, takes 45 minutes.

If you are having Prolotherapy there is no blood draw necessary, the injection is given the same as PRP.

How often are Injections Given?

After the initial treatment, a follow up visit is scheduled 2-4 weeks later to evaluate healing progress. Some patients respond very well to just one treatment. However, 2-3 treatments may be necessary in some injuries and 3-6 for Prolotherapy. If multiple injections are given, injections are typically given every 2-4 weeks.

What Conditions Benefit From PRP/ Prolotherapy?

PRP treatment works for acute and chronic ligament and tendon sprains/strains that have failed other conservative treatment, including:

  • Rotator cuff injuries
  • Shoulder pain and instability
  • Tennis & golfer’s elbow
  • Hamstring and hip strains
  • Knee sprains and instability
  • Patellofemoral syndrome and patellar tendinosis
  • Ankle sprains
  • Achilles tendinosis & plantar fasciitis
  • Knee, hip, and other joint osteoarthritis
  • Sports hernias & athletic pubalgia
  • Loose or subluxing joints
  • Plantar Fasciitis
  • Tendonitis
  • Soft tissue pain around joints
  • Shin Splints
  • Arthritic Pain
  • Other chronic tendon and ligament problems
  • In addition, PRP can be very helpful for many cases of osteoarthritis (the "wear & tear" kind).
  • PRP can help stimulate a "smoothing over" of the roughened and arthritic cartilage, reducing the pain and disability of arthritis. This includes:
  • Knee arthritis
  • Hip joint arthritis
  • And other joint arthritis

Is it Covered by Insurance?

Insurance plans, including Medicare, do NOT pay for regenerative injections.

Do PRP Injections Hurt?

Because lidocaine interferes with the platelet function, it is not used during the PRP injection. Unlike a steroid injection, there may be pain for the next few days after an injection. For the days preceding the injection and for the first week after the injections it is critical to avoid anti-inflammatory medications, including Advil, Motrin, ibuprofen, Aleve, Celebrex and aspirin (unless prescribed by your heart doctor). These will interfere with the healing response. Tylenol is OK. Your doctor may prescribe pain medication also.

Lidocaine is used for Prolotherapy and it is generally considered a somewhat less painful injection.

Are there risks with these Injections?

Anytime a needle is placed anywhere in the body, even getting blood drawn, there is a risk of infection, bleeding, and nerve damage. However, these are very rare. Other complications, though rare, vary depending on the area being treated, and will be discussed by your doctor before starting treatment. Because PRP uses your own blood adverse reactions are rare.

What is the Success Rate?

Studies suggest an improvement of 80-85%. Some patients experience complete relief of their pain. The results are generally permanent.

*At this time we are not providing Stem Cell therapy secondary to the extremely high cost and lack of evidence that it is of any greater benefit than Prolotherapy or PRP.

Additional Spiritual Resources During COVID-19

For prayers and spiritual care requests please email CurtisMcFarland@yvmh.org

Tele-Chaplaincy

There are times when a direct face to face spiritual care conversation is not the best option (due to distance, a pandemic, patient preference). That's where Tele-Chaplaincy provides another possibility. You can request chaplain support using your personal or hospital room phone to connect confidentially with a hospital chaplain. Chaplains will listen, provide encouragement, offer help and resources, if you are part of a faith community the chaplain can help you connect with them, and, if desired, the chaplain can provide prayer.
