Abstract

This study accurately quantifies the knee joint kinematics associated with sidestep cutting maneuvers in vivo. These data were subsequently evaluated to determine the relationship between sidestep cutting and non-contact anterior cruciate ligament (ACL) injury. Sixteen male subjects, proficient in the sidestep cutting maneuver, had knee joint kinematic data recorded during the stance phase of straight line running and sidestep cutting. Cutting speeds (5.5 msec-1 to 7.0 msec-1) and angles (30 degrees to 55 degrees) were chosen to reflect the sporting context. All subjects underwent medical screening prior to testing to ensure data represented joint biomechanics of healthy, ACL intact individuals. The temporal three dimensional positions of externally mounted (skin) markers were submitted to a custom software package (JTMOTION), which described in clinically meaningful terms, movements for the three rotational degrees of freedom at the knee joint. While mean patterns of motion for the three clinical knee rotations compared favorably between running and cutting data, sidestepping induced significantly (p < 0.01) greater maximum knee joint rotations during stance. Knee joint rotational ranges were also found to be significantly (p ...Continue Reading
