Dr. Tim Hewett gave an outstanding keynote address as our 2013 Littlejohn Family Lecturer covering his life-changing research into prevention of ACL injuries. More than 100 attendees comprised of physicians, veterinarians, engineers, basic scientists, physical therapists, athletic trainers, nurses, and students were treated to Dr. Hewett’s impressive and inspiring talk, followed by outstanding presentations from Mizzou clinicians and researchers. This year’s Comparative Orthopaedics Day lived up to the world class quality we have come to expect from this event, and we plan to expand it even further for 2014.
