Anderson Cooper and Dr. Sanjay Gupta explained PRP and the treatment of Tiger Woods on AC360 on December 17. The PRP segment is informative and easy to understand. Cooper and Dr. Gupta discuss Dr. Anthony Galea use of PRP in Woods' knee following surgery. Although Dr. Galea has been arrested for distribution of Human Growth Hormone in the US, there has been no indication Tiger had any association with this practice.
While PRP is "blood spinning," it should not be confused with "blood doping." This segment distinguishes blood spinning as acceptable and beneficial practice.
