Orthopedic Bioengineering Laboratory
The Orthopaedic Bioengineering Laboratory was established on April 15, 1998. Since that time, Dr. Gill and Dr. Guoan Li have directed the laboratory's ground-breaking investigations into sports-related knee and shoulder joint injuries and biomechanics. They have authored numerous publications, and their research has been widely presented nationally and internationally. Dr. Li has joint faculty appointments at the Massachusetts Institute of Technology and Harvard Medical School. He is an advisor to graduate students at MIT and postdoctoral fellows conducting orthopaedic biomechanics research.
Upon establishing the laboratory, its focus was on the novel application of robotic technology to the in-vitro motion simulation of the human upper and lower extremity. Using this robotic technology, the laboratory pioneered the investigation of in-vivo knee joint kinematics, and was the first to generate a new conceptual technology for ACL reconstruction – the single tunnel double bundle ACL reconstruction.
In 2003, the laboratory established a dual fluoroscopic image system (known currently as DFIS in the literature) that could accurately determine in-vivo 6 degree of freedom musculoskeletal joint kinematics. This technique has since contributed to a series of papers reporting the in-vivo function of the human ankle, knee, elbow, shoulder and spine. Many of these works were the first data ever observed in these musculoskeletal joints. For example, the laboratory was the first to report on the in-vivo cartilage deformation of the ankle and knee under weightbearing conditions. In the recent years, the laboratory has been involved in orthopaedic translational research, such as developing new ACL, PCL, and posterolateral corner reconstruction techniques aimed at preventing post-operative joint degeneration.
