Research

By stimulating and sponsoring appropriate orthopaedic research we initiate the development of new ideas and approaches to sports medicine. Recent structural changes in the U.S. medical system are forcing physicians and hospitals to strive to identify the most effective treatment pathways and offer these treatments to their patients, rather than allow managed care to dictate the decision making process. This can be accomplished through research efforts designed to explore and enhance the quality and efficiency of the care provided and to validate the need for certain treatment pathways for special populations, such as those sustaining sports injuries. Our ongoing research projects are changing how orthopaedic care is delivered throughout the world.

Accolades
