Regenerative medicine researchers in sports medicine are studying state-of-the-art, minimally invasive procedures and interventions, such as stem cells, platelet-rich plasma, viscosupplementation, ultrasound, growth factors and amniotic products, to promote healing of musculoskeletal injuries. As this knowledge of musculoskeletal injuries advances, the treatment strategies also advance.
Faculty members collaborating on research related to promoting healing of musculoskeletal injuries using regenerative medicine include:
