Louis DeFrate, PhD
Associate Professor of Orthopaedic Surgery, Duke University
Durham, North Carolina

Dr. DeFrate is the Frank H. Bassett III, M.D. Associate Professor of Orthopaedic Surgery at Duke University. He also holds appointments in the Department of Mechanical Engineering and Materials Science and the Department of Biomedical Engineering. Dr. DeFrate’s research focuses on the application of engineering principles to investigate clinically relevant problems related to the musculoskeletal system. Dr. DeFrate has published widely on the use of MR imaging and biplanar radiography to measure in vivo joint function and cartilage loading in normal subjects as well as those at high risk for the development of osteoarthritis. Dr. DeFrate has also used these techniques to quantify in vivo ligament and tendon deformation. Additionally, he has recently developed a new “stress test” of the knee for evaluating changes in the mechanical and biochemical environments of cartilage in response to activities of daily living. By combining these approaches with MRI sequences that non-invasively quantify tissue composition as well as local and systemic biomarkers of tissue metabolism, innovative analyses of joint health can be performed. Using this approach, Dr. DeFrate has led a number of clinical research projects at Duke University Medical Center, including several NIH grants related to cartilage degeneration after ligament injury and ACL injury mechanisms. His work in this area has recently been acknowledged by the 2016 Kappa Delta Young Investigator Award from the American Academy of Orthopaedic Surgeons (AAOS) and the Orthopaedic Research Society (ORS). Other recent awards include the 2017 Women’s Health Issues Advisory Board Best Poster Award from the AAOS and ORS and the 2017 Best Poster Award from the Meniscus Section of the ORS.

He currently is a member of American Journal for Sports Medicine General and Electronic Media Editorial Boards. His research interests are in upper extremity overuse injury prevention and general orthopedic trauma. Recently, he has developed an interest in technology and innovation by routinely using telemedicine in his sports medicine practice. He leverages telemedicine technology to streamline the patient clinical experience. In addition, he uses technology to provide virtual consultations to general pediatricians, physical therapists, and athletic trainers. He is currently piloting a program to hold a virtual “training room” and provide real-time, virtual coverage of athletic events. As a budding entrepreneur, his future aspiration is to create an app-based, national platform to utilize telemedicine to triage, navigate, evaluate, and treat patients during their clinical experience.

Sam Oussedik, BSc, MBBS, FRCS(Tr&Orth)
Director of Surgical Education, University College Hospital London
London, United Kingdom

Sam trained as an undergraduate at St Bartholomew’s Hospital. He went on to join the North West Thames orthopaedic training rotation following a period devoted to stem cell research. He continued to develop his interest in lower limb surgery in general and knee surgery in particular. In 2010, he spent a year as the Knee Fellow at the Royal North Shore Hospital in Sydney and team doctor for the Gordon Highlanders rugby union team, gaining further specialized experience in knee and sports surgery.

Collaborations with the team at the Sydney Orthopaedic Research Institute culminated in several publications on sports and arthroplasty topics.

Sam was appointed to University College Hospital London in 2012 as a lower limb surgeon with a special interest in knee surgery. His elective practice is 90% knee based, including all aspects of knee surgery from ligament reconstruction and joint preservation work to primary and revision arthroplasty. He also retains a keen interest in general trauma.

His research interests include joint preservation through cartilage restoration and osteotomy about the knee and gaining the best performance from knee arthroplasty.  His studies include using computer navigation hardware to gain a better understanding of knee kinematics, the response to injury and the effects of surgical interventions; imaging cartilage in novel ways to evaluate the effects of treatments; and using cell based therapies in the early stages of osteoarthritis.

As the Director of Surgical Education at UCLH, Sam runs a number of instructional courses for basic and higher surgical trainees as well as masterclasses for fellow lower limb specialists. He is the co-author of books on trauma care and knee arthroplasty as well as an ever-increasing number of peer-reviewed publications.

In addition to editorial board duties with AJSM and OJSM, Sam is the Knee Editor for the Bone and Joint Journal.

In 2016, Sam was fortunate enough to be selected for the ABC travelling fellowship and gained a great insight into the US and Canadian Health systems.

Chicago, Illinois

Mark Grabiner is a professor in Kinesiology & Nutrition, a professor in the Department of Bioengineering, and an Associate Vice-Chancellor for research and Research Integrity Officer at the University of Illinois at Chicago.  He is the founder and director of the Clinical Biomechanics and Rehabilitation Laboratory. Dr. Grabiner earned his doctorate from the University of Illinois, Urbana-Champaign and served on the faculty at the University of Southern California in the Department of Exercise Science, and then at The Cleveland Clinic in the Department of Biomedical Engineering, before joining UIC in 2001.  He has published over 135 refereed publications and has contributed to 10 books.  His interdisciplinary research involves characterizing the modifiable mechanisms underlying falls and injuries by older adults and translating these findings to the design, development, and deployment of clinically-relevant technologies and interventions.  During the course of his career, the research to which he contributed has received more than $20 million in extramural funding.  He is a fellow of the American Society of Biomechanics, the Gerontological Society of America, the American College of Sports Medicine, and the American Academy of Kinesiology.  He has served as the president of the American Society of Biomechanics, as a member of the executive Council of the International Society of Biomechanics, and as a member of the World Council on Biomechanics.
