Description

Abstract:: The studies presented in this dissertation describe and apply methods for using biplanar videoradiography to study dynamic in vivo knee motion. The techniques presented in this dissertation were applied with the goal of better understanding the kinematics and kinetics associated with non-contact deceleration ACL injury during a jump-cut maneuver in anterior cruciate ligament (ACL) -intact (ACLint) and ACL-reconstructed (ACLrec) male and female recreation athletes. The long term objective of this work is to inform novel injury prevention and rehabilitation programs that mitigate the injury risk, improve injury recovery, and reduce risks associated with re-injury and post-traumatic joint degradation. The specific aims were to: (1) develop and validate methods for accurately quantifying in vivo knee bone motion using biplanar videoradiography; (2) collect and quantify the kinematics of individuals performing a jump-cut maneuver; and (3) investigate gender and ACL reconstruction status differences in kinematics and kinetics of ACLint and ACLrec subjects performing the jump-cut maneuver. We were successful in developing and validating a method to for measuring dynamic in vivo bone motion within 0.25° using biplanar videoradiography. Additionally, we successfully developed a robust algorithm for determining anatomical coordinate systems for the distal femur and proximal tibia (bias < 1.5mm & 2.5°). Building on these studies, we successfully designed and implemented an experimental protocol for the combined measurement of optical motion capture (OMC), biplanar videoradiography, ground reaction force, and muscle activity during the jump-cut maneuver. From these data, we show that secondary knee joint rotations and all knee joint translations, as measured by OMC, are associated with significant kinematic errors due to soft tissue artifact during the jump-cut maneuver. However, the results suggest that OMC is sufficient for measuring sagittal plane knee kinematics during the jump-cut maneuver. Finally, these tools, techniques, and protocols were used to compare the knee kinematics and kinetics of ACLint and ACLrec male and female recreational athletes while performing the jump-cut maneuver. Both gender and ACL reconstruction status differences were observed in the knee kinematics and kinetics. Moreover, the results associate an increased rate of anterior tibial translation to increased landing stiffness while performing the jump-cut maneuver.
