From the March issue: Patient-Reported Outcomes and Knee Mechanics Correlate With Patellofemoral Deep Cartilage UTE-T2* 2 Years After Anterior Cruciate Ligament Reconstruction

Podcast: Listen to Dr. Chu discuss her article in the March issue.


Dr. Constance R. Chu is Professor and Vice Chair Research, in the Department of Orthopedic Surgery at Stanford University and Director of the Joint Preservation Center at the VA Palo Alto. She is a surgeon-scientist who has been awarded more than $20 million in federal research grants from the National Institutes of Health (NIH), the Veterans Administration (VA), and the Department of Defense (DOD) for innovative bench to bedside work in regenerative medicine, quantitative MRI, and the prevention of osteoarthritis (OA). The central goal of her research program is to transform the clinical approach to osteoarthritis from palliation to prevention. Dr. Chu’s work has been recognized by more than 30 professional honors to include two Kappa Delta Awards, considered to be the highest research honor in Orthopedic Surgery. Her clinical practice focuses on the knee: primarily reconstruction and restoration of the anterior cruciate ligament (ACL), menisci and cartilage.

Dr. Chu graduated from the U.S. Military Academy at West Point. Following distinguished military service, she earned her medical degree from Harvard Medical School. She was previously the Albert Ferguson Endowed Chair in Orthopedics and Bioengineering at the University of Pittsburgh where she was recognized as a Pittsburgh “Top Doctor”, as well as on Becker’s list of Top Knee Surgeons in the United States. Dr. Chu is alumnus of the American Orthopedic Association American, British, Canadian (ABC) and the American Orthopedic Society for Sports Medicine (AOSSM) Traveling Fellowships. She is also past President of the Forum Sports Focus Group, past Chair of the AOSSM Research Council, and Co-Chair of the AOSSM Diversity Task Force.
