TT Holdings is dedicated to producing smart devices that can protect against severe injury. The company is focused on teaching and training scientifically – proven principles to athletes and workers to keep them healthy.

TT Holdings was founded by a practicing orthopedic surgeon and sports medicine specialist, Terry Younger, MD. His years of clinical experience in the operating room as well as on the sidelines treating sports and workplace injuries led him to discover methods of preventing season-ending and sometimes career-ending trauma. Progressing from known clinical research that showed significantly less likelihood of injury after performance of exercise protocols, Dr. Younger made the next leap forward, developing a unique patented technology that aids in effectively and safely performing training programs to prevent injury.

The first commercially available device is the TyTec PrevenTec knee device which teaches and monitors the performance of a protective knee exercise regimen. In addition, proven principles for jumping that can help to avoid injury are incorporated into the software package and data can be stored or transmitted for review.
