Experimental Investigation of the Response of the Human Lower Limb to the Pedestrian Impact Loading Environment 2005-01-1877
Three limbs were taken from post mortem human subjects and impacted on the lateral aspect by a free-flying (30 km/h) impactor below the knee joint. Tri-axial MHDs and tri-axial accelerometers were used to determine the kinematics of the limb; strain gages were used to measure surface strain on the tibia and femur; and acoustic sensors were used to identify the onset and timing of injury. This data set was analyzed to compute the response of the knee joint to a bumper impact. Post-test necropsy results showed that the primary injury mechanism in each case was complete avulsion of the Medial Collateral Ligament (MCL) and the Anterior Cruciate Ligament (ACL).
