Platelet Rich Plasma (PRP)

Platelet are small cells whose role is generally considered in forming a clot of blood to prevent bleeding in the time of injury. PRP is proving to be a versatile and effective method of treatment for a number of conditions due to its very rich supply of growth factors which are produced within the platelets’ granules and are ready to be act on our injured tissues. In contrast, regular prolotherapy must incite the production of these growth factors. Over 7,600 articles, including thousands of research projects, have been published in recent years on PRP.

Platelet rich plasma (PRP) is a method whereby the patients’ blood is taken, spun, and platelets are concentrated; the rest of the blood is discarded. The platelets are then injected into the injured area.
There are many methods of producing PRP. One can spin the blood manually in a centrifuge and extract the platelets, or one can use specially equipped centrifuges which automatically separate the blood producing the desired concentration of platelets. The disadvantage of the latter is that the kit required for every treatment is very expensive, in the order of between 1,200 and 2,000 NIS and this does not include the doctor’s treatment. At the moment PRP is not covered by the Israel Health Funds. Because of this huge expense, I chose to use the manual method, making this considerably cheaper.

PRP has been used in:

  • the treatment of orthopedic disorders, such as partial tendon and ligament tears,
  • Tendinosis and degenerative arthritis
  • bone and tendon grafts
  • dental implants
  • aesthetic medicine; hair regrowth for men, anti-aging facial treatments for women

Growth factors released by platelet granules include:

  • Platelet derived growth factor: for connective tissue proliferation
  • Transforming growth factor: for extracellular matrix and collagen synthesis
  • Vascular endothelial growth factor: for angiogenesis
  • Insulin-like growth factor: for collagen synthesis
  • Fibroblastic growth factor: for collagen, cartilage and muscle repair, skin aesthetics
  • Platelet derived epidermal growth factor: for skin repair (de Vos et al. 2010; De Pascale et al. 2015; Pintan et al. 2014)

Dr Galea, a well-known Canadian sports physician, has treated hundreds of Olympic sportsman using these techniques with good long term success, enabling them to get back to their original sports. He presented his ideas on Ted talk
