This study provides information on the kinematic discrepancies between OMC and biplanar videoradiography that can be used to optimize methods employing both technologies for studying dynamic in vivo knee kinematics and kinetics during a jump-cut maneuver.Īctivities involving jumping, landing, and cutting are commonly associated with non-contact anterior cruciate ligament (ACL) injuries ( Griffin et al., 2006 Gianotti et al., 2009). Kinematic deviations between the two techniques increased significantly after contact. The OMC and biplanar videoradiography knee joint kinematics were in best agreement before landing. Over the entire activity, the within-bone motion differences between the two motion capture techniques were significantly lower for the tibia than the femur for two of the rotational axes (flexion/extension, internal/external) and the origin. The knee joint kinematic measurements were compared during two periods: before and after ground contact.

The within-bone motion differences were compared using anatomical coordinate systems for the femur and tibia, respectively. Ten volunteers performed a jump-cut maneuver while their landing leg was imaged using optical motion capture (OMC) and biplanar videoradiography. The goal of this study was to compare how STA affects the six-degree-of-freedom motion of the femur and tibia during a jump-cut maneuver associated with non-contact ACL injury. Biplanar videoradiography offers a unique approach to collecting skeletal motion without STA. Optical motion capture is widely used however, it is subject to soft tissue artifact (STA).
