After graduating Phi Beta Kappa and Magna Cum Laude in Biology from Harvard College, Dr. Thomas Gill received his MD from Harvard Medical School. He completed his training in orthopaedic surgery at the Harvard Combined Orthopaedic Residency Program. After graduating, Dr. Gill was awarded the Maurice E. Muller Scholarship to study reconstructive surgery in Bern, Switzerland and other European academic centers. He completed his fellowship training in Sports Medicine and Shoulder Surgery at the Steadman-Hawkins Clinic in Vail, Colorado.

Dr. Gill is an Associate Professor of Orthopaedic Surgery at Harvard Medical School. He has served as Chief of the MGH Sports Medicine Service and Director of the Sports Medicine Fellowship Program. He has been named to the "Top 1% of Doctors in America" and consistently is listed among the "Best Doctors in America" and "Best of Boston" physicians.

Dr. Gill is Director of Research for the Sports Medicine Service, has published over 140 peer-reviewed manuscripts and edited two text books in knee and shoulder surgery. He has received multiple research awards, including the prestigious Excellence in Research Award, Aircast Award, O'Donoghue Award and Hughston Award from the American Orthopedic Society for Sports Medicine. He is a fellow of the American Association of Orthopedic Surgeons, a member of the American Orthopedic Society for Sports Medicine, and a member of the Team Physician Societies of the NFL and the NHL. His work is recognized both nationally and internationally. He has been elected to the Herodicus Society, the honor society for Sports Medicine surgeons, and the American Orthopedic Association.


Dr. Gill has a particular interest in biomechanics of the knee and shoulder, as well as tissue engineering techniques for joint preservation and cartilage repair in the knee. Dr. Gill is Co-Director of the MGH Orthopedic Bioengineering Laboratory, where he has helped to establish a robotic and cadaveric study protocol designed to investigate the biomechanical consequences of ligament injuries in the knee. His primary focus is to determine the effects of injury to the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) in the knee. More importantly, he studies the effects of subsequent ACL and PCL reconstruction on knee joint function and the potential for future arthritis, with a goal to determine whether such degenerative changes can be prevented through different surgical reconstructive techniques.

Dr. Gill plans to extend the use of the robot model to the shoulder joint in an effort to study the biomechanics of the throwing motion. He has collaborated on the establishment of the first, live, 3-dimensional imaging system using fluoroscan, dynamic MRI and computer modeling that has enabled him to directly evaluate the degree of function in an injured joint and actual restoration of function after surgical repair. Most recently, Dr. Gill has helped to build a pioneering, new Sports Performance Analysis Center at Patriot Place in Foxborough to study both healthy and injured athletes of all levels while performing their sports, such as pitching, swinging a golf club, or kicking a soccer ball. The goal of this technology is to improve an athlete's function and performance.

Dr. Gill's second research focus is tissue engineering. He is currently studying the use of cell-seeded biologic scaffolds to perform cartilage repairs in the knee. Many of these repairs have not been previously possible without such biologic engineering. The goal of these studies is to help preserve joints, and prevent the need for total joint replacements.
