Martha Murray, MD, is an orthopaedic surgeon at Boston Children's Hospital and a Professor at Harvard Medical School. She has developed a novel technique of Bridge-Enhanced® ACL repair which utilizes a bio-engineered scaffold to stimulate healing of the ligament instead of the traditional harvesting of a graft of tendon to replace the torn ACL. She has over 80 peer-reviewed publications around this development. She has won the AAOS Kappa Delta Award for this work, was named one of Fast Company's Top 100 Most Creative People in Business in 2015, as well as being featured in Stephen Hawking's Brave New World Series. Dr Murray has a BS in Mechanical Engineering from the University of Delaware, a MS in Materials Science and Engineering from Stanford, and received her MD from the University of Pennsylvania prior to completing residencies and fellowships at Harvard Medical School. If you would like information about the BEAR® technique for ACL surgery, please visit or email us at Boston Children's Hospital is currently the only location where this surgery is performed.

About The ACL Study Group

The ACL study group was organized 25 years ago by a small group of orthopedic surgeons with a common interest in the anterior cruciate ligament. Today, Dr. John Bergfeld organizes this large international study group that meets every 2 years to exchange information in an informal and friendly atmosphere.
