Tyler Johnston, MD 


Born in Fairbanks, Alaska and raised on a farm at the foot of the Rocky Mountains in Fort Collins, Colorado, Dr. Johnston learned an early appreciation for nature and human athleticism through a variety of endeavors including rock climbing, snowboarding, hiking and biking. When he made the move to Palo Alto, California for his undergraduate education at Stanford University he continued to strengthen this affinity, surfing the cold waters of Northern California while investigating the form and function of the human body in his human biology major.

After he completed his B.A., graduating Phi Beta Kappa, he went on to complete a Master of Science in Mechanical Engineering, also at Stanford, with an emphasis in biomechanical engineering and medical device design. During this time he worked as a research and teaching assistant in the Stanford Human Performance Laboratory and participated in a variety of research and design projects ranging from bone mechanobiology to robots, gait training and sports safety devices, fostering his interests in health tech innovation as well as orthopaedics.

He subsequently went on to attend medical school and complete orthopaedic surgery residency at Stanford. While focusing his coursework and creative energy on bioengineering, he pursued research in cartilage, stem cells, and biomechanics for which he has received awards, published and presented nationally and internationally.

Dr. Johnston was honored by the opportunity to train in the great tradition of Duke orthopaedics and sports medicine for fellowship and to be selected for the Feagin Leadership Program. He maintains strong interests in healthcare innovation, as well as biomechanics and outcomes of musculoskeletal reconstruction techniques. He enjoys exploring the waves, nature trails and golf courses of North Carolina whenever not advancing his orthopaedic techniques or covering Duke and NCCU sports teams.
