Research suggests that females are more likely to sustain an anterior cruciate ligament (ACL) injury when compared to males and that the ACL and hamstring muscles work together to preserve joint stability. Information is limited regarding any relationship between anterior knee joint laxity, in the absence of injury, and eccentric hamstring time to peak torque. This study compared anterior knee joint displacement and eccentric hamstrings time to peak torque in 30 female athletes and 30 female non-athletes ages 14-18 years. The passive anterior drawer was measured on both lower extremities using the KT-1000® arthrometer before and after eccentric hamstrings time to peak torque testing on the Biodex® System 2 isokinetic dynamometer. Data were collected at two speeds, 90°/second and 150°/second. Results of this study suggest there is no relationship between eccentric hamstrings time to peak torque and anterior knee joint displacement in the two populations tested.
