From the May issue: Bridge-Enhanced Anterior Cruciate Ligament Repair Is Not Inferior to Autograft Anterior Cruciate Ligament Reconstruction at 2 Years: Results of a Prospective Randomized Clinical Trial

Podcast: Listen to Dr. Murray discuss her article in the May issue.


Martha Murray, MD, is a Professor of Orthopaedic Surgery 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 and translated it from the lab to the operating room with grant funding from various sources, including the NIH and NFL Players association.  She has founded a company, MIACH Orthopaedics, to manufacture the scaffold.  She has 9 issued patents and over 100 peer-reviewed publications around the development of this technology, including the most cited article in the Orthopaedic Journal of Sports Medicine.  She has won the AAOS Kappa Delta Award, been named one of Fast Company’s Top 100 Most Creative People in Business, been featured in Stephen Hawking’s Brave New World Series and been featured in a video on Tech Insider that garnered over 65 million views.  Martha 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.
