Lower limb kinematics and dynamic postural stability in anterior cruciate ligament-reconstructed female athletes.

Context: Deficits in lower limb kinematics and postural stability are predisposing factors to the development of knee ligamentous injury. The extent to which these deficits are present after anterior cruciate ligament (ACL) reconstruction is still largely unknown. The primary hypothesis of the present study was that female athletes who have undergone ACL reconstruction and who have returned to sport participation would exhibit deficits in dynamic postural stability as well as deficiencies in hip- and knee-joint kinematics when compared with an age-, activity-, and sex-matched uninjured control group.

Hip and knee joint kinematics during a diagonal jump landing in anterior cruciate ligament reconstructed females.

Anterior cruciate ligament (ACL) injury is a common injury encountered by sport medicine clinicians. Surgical reconstruction is the recommended treatment of choice for those athletes wishing to return to full-contact sports participation and for sports requiring multi-directional movement patterns. The aim of ACL reconstruction is to restore knee joint mechanical stability such that the athlete can return to sporting participation.

Lower limb kinematic alterations during drop vertical jumps in female athletes who have undergone anterior cruciate ligament reconstruction.

The aim of this study was to determine if anterior cruciate ligament reconstructed (ACL-R) female athletes exhibit altered lower limb kinematic profiles during jump landing when compared to a non-injured age, sex, and activity matched control group. Fourteen ACL-R and 14 non-injured control subjects performed 3 vertical drop jump (DVJ) trials. Lower limb kinematics were recorded at 200 Hz.
