This episode describes what the real definition of a stem cell is and how we obtain them for use in Orthopedics and Sports Medicine. We discuss the ways in which the current evidence shows that they help people with injuries with arthritis as an example. We also discuss whether getting stem cells from the bone marrow or the fat is the ideal source and where the FDA stands on all of this. Have questions?
