Platelet Rich Plasma (PRP)

 

What is PRP?

It is using one’s own plasma…containing platelets injected into the painful, injured site of a tendon or Bursa.

Platelets are selected because they form a fibrin clot containing growth factors that enhance tissue healing .

What is Platelet Rich Plasma?

Platelet Rich Plasma, or PRP, is blood plasma with concentrated platelets. The concentrated platelets found in PRP include growth factors that are vital to initiate and accelerate tissue repair and regeneration. These bioactive proteins initiate connective tissue healing and repair, promote the development of new blood vessels, and help stimulate the wound-healing process.

How does PRP work?

To prepare PRP, a small amount of blood is drawn from the patient. The blood is then placed in a centrifuge. The centrifuge spins and separates the platelet-rich plasma. This increases the concentration of platelets and growth factors up to 500 percent, increasing the healing capabilities of the damaged or weakened connective tissue being treated. When PRP is injected into the damaged area, it stimulates the tendon or the ligament, causing mild inflammation that triggers the healing cascade. As the collagen matures, it begins to strengthen the tendons or ligaments of the damaged area. What can be treated? PRP injections can be performed in tendons and ligaments all over the body. Sports injuries such as Tennis elbow, Bursitis, Golfer elbow, and other tendinopathies may all be treated effectively with PRP.

It’s called Platelet Rich Plasma therapy — or PRP. Doctors spin a few tablespoons of a patient’s own blood, separating out the platelets. Normally, platelets help the blood to clot — but they also promote healing. With PRP, this concentration of platelets is injected directly into the injury. Platelets are an amazing substance. They are packed full of growth and healing factors, and when given into a specific area, you get a hyper-healing response. PRP has been safely used for 20 years without reported complications or safety issues. Its origins lie in the dental field. However, it is being applied in numerous specialties to accelerate healing. Platelet-rich plasma (PRP) therapy has recently appeared as a new treatment for arthritis. A Cornell University researcher recently showed that platelet-rich plasma (PRP) therapy could enhance the healing response and quality of repair at the cellular level in treating tendonitis.

Mitek’s New PEAK Platelet-Rich Plasma System Separates Blood in 2.5 Minutes

July 14th, 2014 Medgadget Editors Orthopedic Surgery

Mitek Sports Medicine, a J&J firm, has unveiled a new PEAK Platelet Rich Plasma (PRP) System that separates PRP from the patient’s own blood. Used by sports medicine physicians to treat a variety of injuries and disorders, PRP is still a relatively new biologic tool in practice.

The PEAK system lets clinicians obtain 3mL of high quality PRP from 27mL of whole blood within two and a half minutes. It concentrates platelets 7.8 times baseline. That compares to anywhere from ten to thirty minutes on competing devices, according to Mitek. The device weighs four pounds (~ 2kg) and has a small footprint.
