How to prevent knee injuries: Dr. Lou DeFrate and his research team featured by KSAT for work studying the causes of ACL tears


As an undergraduate Duke cheerleader, Hattie Cutcliffe held the record for the most back handsprings across Cameron Indoor Stadium. Now a Duke scientist & PhD candidate, she's studying ways to prevent ACL tears, a painful knee injury she herself experienced.

“There are over 400,000 ACL tears in the U.S. each year,” Louis E. DeFrate, PhD, Frank H. Bassett III, MD, Associate Professor of Orthopaedic Surgery, Biomedical Engineering, and Mechanical Engineering and Materials Science, Duke University explained.

DeFrate and his research team at Duke University are studying the causes of ACL tears. In the hopes of preventing this type of injury, DeFrate and his team created a ‘stress test,’ combining MRIs of the knee with high tech X-ray imaging.

“We can see which positions the ACL is stretched the most and when it’s most likely to fail,” DeFrate said.
