Platelet rich plasma (PRP) is a highly concentrated collection of plasma obtained from a patient’s own blood. A sample of blood is taken from the patient, then via centrifuge, concentrated down to a collection of platelets, proteins, enzymes, and growth factors that are key in the body’s own regenerative process. This distilled collection can then be injected into an area of injury in order to accelerate healing. It has been used extensively in the world of professional sports, but is also used around the world for patients and athletes of all skill levels.
PRP works by stimulating an inflammatory response in a site of injury. It is part of a larger field known as Orthobiologics, which includes proinflammatory therapies. Since inflammation is the body’s main mechanism for repair, we are able to guide an inflammatory response into the problem spot or injury area, thereby kickstarting the recovery process on a tissue level.
A number of areas may be treated with PRP. Most commonly, it is used to treat areas of tendon injury or injected directly into joints. Here at Pravan Health, all of these injections are done in a sterile manner with the use of ultrasound guidance to allow injection into the area where it will be of most benefit. It’s important for PRP to be injected into very precise areas, because it may not prove effective otherwise.
This therapy is different from steroid or cortisone injections. Cortisone is used to inject into bursae, joints, or around inflamed areas to stop inflammation and therefore decrease pain. Unfortunately, by stopping all inflammation, steroid injections may do more damage long term, although they do provide a short-term pain relief benefit. Multiple studies have shown that repeated steroid injections into a joint or tissue are associated with worsening of tissue quality at the site, and may lead to an increased need for surgical interventions down the road. PRP, on the other hand, encourages healing, and is of used for pain relief on a longer-term basis, and with a goal of postponing or negating the need for surgical interventions.
When using PRP therapy it is important to understand that it should not be considered an immediate fix, and occasionally, multiple injections will be necessary for tissue regeneration and healing. It is also important to avoid all anti-inflammatory medications after having the procedure as this will stop the all-important inflammatory response that we are trying to create. Some conditions which may benefit from PRP therapy include:
- Rotator Cuff tendinopathy or degeneration
- Knee osteoarthritis
- Plantar Fasciitis
- Patellar tendinosis/tendinopathy (jumper’s knee)
- Quadriceps tendinopathy
- Greater trochanteric pain syndrome (formerly called trochanteric bursitis)
- Iliotibial (IT) band syndrome
- Chronic ankle sprains
- Achilles injury or tendinopathy
- Medial and Lateral epicondylitis (Golfer’s Elbow and Tennis Elbow)
