Jason L. Dragoo, MD
Associate Professor of Orthopaedic Surgery
Stanford University
Redwood City, CA

Jason L. Dragoo, MD, is an Associate Professor of Orthopaedic Surgery at Stanford University. He specializes in Sports Medicine and currently serves as a team physician for Stanford University Athletics, where he is the Head Team Physician for the Stanford Football Program and serves on the Board of Directors for the PAC 12 Conference Health and Wellness Committee. He has previously served as a physician for the US Ski Team, US Olympic Committee and has also served on the AOSSM Research Committee.  He is also an active member of the AAOS and currently serves on the Biologics Committee and has advocated for the use of autologous cell therapy to the FDA.

His basic science and clinical research has led to many advances in the use of biologics to augment tissue healing including: 1) investigations on the formulations and applications platelet rich plasma (PRP) and autologous growth factors, 2) cartilage regeneration using adult adipose-derived stem cells, and 3) the development of 2nd generation methods, using autologous blood products, for tissue repair. He currently is an investigator on 5 NIH grants, has published 3 textbooks, and authored over 70 peer-reviewed articles.

Robert F. LaPrade, MD, PhD is a board-certified orthopaedic surgeon with a certificate of added qualification in sports medicine.  Dr. LaPrade is a complex knee and sports medicine specialist at The Steadman Clinic in Vail, Colorado.  He is co-director of the sports medicine fellowship program, Chief Medical Officer, and Director of the International Scholars Program at the Steadman Philippon Research Institute.  Dr. LaPrade completed his residency at the Michigan State University-Kalamazoo campus and his sports medicine fellowship at The Hughston Clinic in Columbus, Georgia.  He was an AOSSM traveling fellow in 1997.  In 2003, Dr. LaPrade completed his PhD at The University of Oslo.

Dr. LaPrade is a proud graduate of The University of Maine, where he majored in forest engineering.  In 2015, Dr. LaPrade was honored with a Distinguished Alumni Career Award from The University of Maine for recognition of his academic career.

Prior to joining The Steadman Clinic in 2010, Dr. LaPrade worked at the University of Minnesota from 1996 to 2010.  During that time, he was team physician for The University of Minnesota men’s ice hockey and baseball teams.  The men’s hockey team was the Division I National Champions in 2002 and 2003.  Dr. LaPrade is an adjunct professor in the Department of Orthopaedic Surgery at The University of Minnesota and is also an affiliate faculty at the College of Veterinary Medicine and Biomedical Sciences at Colorado State University.

Dr. LaPrade has published more than 300 articles related to orthopaedic sports medicine in the areas of anatomy, basic science, biomechanics, clinical diagnosis, and clinical outcomes.  His research and his research team have been awarded the Excellence in Research (AOSSM), Aircast (AOSSM), Herodicus, Smith and Nephew Best Paper in Ligaments and Biomechanics (ESSKA), Nicola Foundation (ESSKA), Best of Show Poster (AAOS), Albert Trillat (ISAKOS), and the Achilles Sports Medicine (ISAKOS) awards.  Dr. LaPrade has also been awarded the OREF Clinical Research award, which is considered one of the “Nobel prizes” in orthopaedic surgery, for his comprehensive work on the posterolateral knee.  Dr. LaPrade has also published over 100 book chapters and authored a textbook on posterolateral knee injuries.  He also has a special interest in mentoring medical students, residents and fellows and has been awarded several outstanding teaching awards.

Dr. LaPrade provides care to athletes of all skill levels including high school, collegiate, professional, and Olympic athletes.  In particular, The Steadman Clinic is one of two U.S. Olympic National Medical Centers and Dr. LaPrade treats multiple Olympic athletes as part of this program.

Dr. LaPrade has a special interest in treating complex knee injuries.  He has authored multiple basic science, biomechanical, diagnostic, and clinical outcome studies in this area.  A large number of these studies were performed in collaboration with Lars Engebretsen MD, PhD and his team at the University of Oslo.  His most recent work has centered on the anatomy, biomechanics, diagnosis, and treatment of meniscal root tears.  Dr. LaPrade is particularly proud of working with his two oldest sons, Chris and Matt, on articles that were recently published in AJSM on this topic.

He is a member of multiple sports medicine organizations including AOSSM, AAOS, AANA, ESSKA, ICRS, and ISAKOS.  He is currently the Chair of the Research Committee of AOSSM and Chair of the Sports Medicine Committee for ISAKOS.  Dr. LaPrade has been on the Editorial Board of The American Journal of Sports Medicine since 1998.  Dr. LaPrade has been married to his wife, Sandy, for 26 years and they have 3 sons, Chris, Matt, and Jeff.  Dr. LaPrade and his wife reside in Avon, Colorado.
