Injuries to the knee often disturb the training and competition schedule of people involved in sports activities. In the healthy knee, the muscles surrounding the joint seamlessly work together with the cruciate and collateral ligaments, the menisci, and cartilage inside the joint to create a smooth, balanced knee motion. However, once one or more of the supporting structures is injured during sports, the remaining structures have to work harder in an attempt to stabilize the knee. Frequently, surgical and rehabilitation procedures are required to re-establish the balanced knee motion, and to prevent secondary injury to the other knee structures.

Under the direction of Dr. Guoan Li, the Bioengineering Laboratory research team employs both an in vitro robotic testing system and an in vivo combined dual fluoroscopic and magnetic resonance imaging technique to quantify the biomechanics of the healthy, injured and surgically reconstructed musculoskeletal system. The progress in understanding the injury mechanisms has established physiological guidelines for more accurate ligament reconstruction techniques and optimized rehabilitation protocols.

The Bioengineering Laboratory Sports Medicine Research Group consists of a team of biomechanical engineers, physicists, and physicians, working in close collaboration with the orthopaedic surgeons and physical therapists of the Massachusetts General Hospital Sports Medicine Service to help all patients achieve their maximum potential in sports.
