Regenerative therapies for pain are new and rapidly evolving. This innovative field includes platelet rich plasma (PRP) that was introduced in the 1970s. PRP is made from our own blood.

Orthopedist and sports medicine expert Dr. Alan Hirahara explores the details behind this revolutionary, but still controversial therapy.
