Abstract

The Q-angle has long been hypothesized to be useful in predicting anterior cruciate ligament injury in athletes, but is difficult to reliably measure clinically. Tibial tubercle to trochlear groove is a reliable and accurate measurement that has the potential to replace Q-angle as a predictor for ACL injury. Magnetic resonance images of 42 subjects, 24 with ACL injury and 18 with no ACL injury, were analyzed and mean TTTG compared for differences between groups. A significant increase in mean TTTG (p=.035) was seen in male subjects and a significant decreases in mean TTTG (p=.028) was seen in women over 40. Results indicate TTTG may be useful in predicting ACL injury but further research is needed utilizing prospective measures and focusing on more specific demographics before TTTG can be used to predict ACL injury.
