A PRP article was recently published from Spain reviewing current applications of PRP in orthopaedics. Most interestingly was the discussion surrounding use in professional sports. There is generalized confusion requiring rigorous definition associated with well characterized products and procedures. Currently US olympic athletes are able to receive the treatment under the WADA worl anti-doping agency; however must first apply for approval. There are no specific guidlines in other US professional sports organizations. PRP does not enhance performance & only treats a local injury & therefore should not be considered prohibited.
I expect more & more professional athletes to receive not only PRP but stem cell based therapies to accelerate recovery, both as injections & while undergoing surgery.
