Affinity Sports Medicine & Orthobiologics primarily uses Mesenchymal Stem Cells derived from a Bone Marrow Aspirate (BMA) or a lipoaspirate (fat-LA). Our review of the science shows BMA and LA to be the best source of stem cells for orthopedic pain. There is ongoing science and research into such things as amniotic fluid, umbilical cord blood, umbilical cord matrix, and more. As the science develops on these treatment options, we are dedicated to reviewing the studies and offering the best, most up-to-date treatment options available.
