Platelet Rich Plasma (PRP)

Although blood is mainly a liquid (called plasma), it also contains small solid components (red cells, white cells, and platelets.) The platelets are best known for their importance in clotting blood. However, platelets also contain hundreds of proteins called growth factors which are very important in the healing of injuries.

PRP is plasma with many more platelets than what is typically found in blood. The concentration of platelets — and, thereby, the concentration of growth factors — can be 5 to 10 times greater (or richer) than usual.

PRP preparation,

  1. Blood must first be drawn from the patient.

  2. The platelets are separated from other blood cells and their concentration is increased during a process called centrifugation.

  3. Then the increased concentration of platelets is combined with the remaining blood which is then injected into the area requiring treatment.*  


Regenerative therapy is a good option to pursue after you have exhausted conservative treatments such as physiotherapy, anti-inflammatory and rehabilitation. That said, many of our patients have early degeneration of their joints and want to prevent further deterioration.  Many will choose regenerative treatments to try and head off the need for surgical joint replacements. 

Key Points to Remember:

  • Platelet Rich Plasma (PRP) comes from the patient’s own blood.

  • PRP is a concentrated source of growth factors and cellular signaling factors that play a significant role in the biology of healing.

  • Basic science studies show that PRP treatment may improve healing in many tissues.

  • Anti-inflammatory medicines should be stopped before and after PRP treatment is given.

  • Some new evidence supports combining PRP with an inject-able joint lubricant called hyaluronic acid for knee osteoarthritis.
