Preventing Anterior Cruciate Ligament (ACL) Tears in Female Youth Athletes with Video Game Technology

Anterior cruciate ligament (ACL) knee injuries occur 4 to 6 times more often in females than males.  An estimated 38,000 ACL injuries in girls and women occurred in 2001 resulting in treatment costs of approximately $650M. There are several well recognized abnormalities that have been shown to increase the risk of ACL rupture in females when compared to males. With training, these abnormalities are correctable, leading to a relative risk reduction of 30% to 80%. Dr. Gray and Dr. Skubic have developed screening software using the inexpensive Microsoft Kinect motion sensor that measures these knee angles during a jumping/landing task. (Patent pending). With this research, they are looking to develop an injury prevention program using video game technology. Ideally, their work will allow many more female athletes to be identified as “at risk” and more proactively treated at a much lower cost.
