Dr. Jon Schoenecker

Jonathan Schoenecker, MD, PhD is an orthopaedic surgeon-scientist dedicated to caring for adults and children with orthopaedic trauma and hip conditions, educating future surgeon-scientists, and conducting high impact translational research. His unique focus stems from his surgical training in musculoskeletal diseases in combination with his basic science training in biochemistry, coagulation, and vascular and musculoskeletal biology. The overarching theme of his clinical and basic science research program is to determine the biological mechanisms by which musculoskeletal tissue responds to and recovers from tissue injury. This ‘acute phase response’ is not only essential to prevent exsanguination and infection, but is also a key regulator of tissue repair following injury. Dysfunctional acute phase responses, such as in patients with severe trauma, are significant causes of morbidity and mortality following traumatic musculoskeletal injury, such as bleeding, thrombosis and pathologic wound repair. He is completely dedicated to a career as a surgeon-scientist, improving patients’ lives with surgery and highly translational research.
