Context: Adolescent female athletes are at a 4-6 times greater risk for an anterior cruciate ligament (ACL) injury than male adolescent athletes. Most ACL injuries occur during a non-contact mechanism while decelerating and/or changing direction. Previous research uses unanticipated cutting tasks to recreate realistic scenarios that show an increased load on the ACL when the task is unplanned. Biomechanical and neuromuscular factors can be modified for the athlete to be better prepared for the high demands placed on the knee. Identifying deficits in female athletes during unanticipated cutting maneuvers can contribute to improving mechanics at the knee and work to prevent ACL injuries. Objective: To determine differences in knee biomechanics during an anticipated and unanticipated sidestep cutting task through trunk, hip, knee, and ankle kinematics and kinetics. Study Design: Cross-over study. Setting: Laboratory. Participants: 10 healthy high school female athletes. Inclusion: Healthy with no lower extremity injury in the past six months or cleared by physician. Exclusion: History of ACL injury or repair, previous injury to ankle, hip, or knee in past 6 months, and any vestibular or balance disorders. Intervention: Participant will run 6 m at a speed of 3.5-5.0 m/s toward a force plate to perform either an anticipated or unanticipated sidestep cut or crossover cut. Main Outcome Measures: Kinematic data was assessed using a 12 camera 3D analysis. Kinetic data was assessed using an in-ground force plate. A time series analysis was conducted on the data. Results: No significant differences were found for the frontal plane, sagittal plane, or ground reaction forces for kinematics or kinetics. Conclusion: The data shows a trend that the female athletes were in a more at risk position of sustaining an ACL injury during the unanticipated task compared to the anticipated task.
