Derivation and Theoretical Assessment of a Set of Biomechanics-Based, AIS2+ Risk Equations for the Knee-Thigh-Hip Complex

The probability of sustaining a moderate-to-serious knee-thigh-hip complex (KTH) injury in a frontal crash was estimated using a specially derived set of risk equations in a four-part study. After literature with data on knee-loaded, whole-body, post-mortem human subjects (PMHS) was collected, normalization of attendant response data (such as axial compressive load knee applications) to those of a mid-sized male occurred. A set of risk equations for adults of varying genders and ages was derived using numerous mathematical constructs and statistical analyses. Analysis of National Automotive Sampling System field data occurred for purposes of comparison. Resulting risk equation set fidelity assessment transformed axial compressive femur loads into event risks from simulated, full-engagement frontal crashes. Field-based injury rates were compared with resulting model-based injury rates, with promising results. The average model-based injury rate was 1.10% and the field-based rate was 1.30% in towaway frontal crashes involving unbelted drivers in 1985-1997 model year passenger cars with less than 58 km/h speed changes. The model confirmed some field trends, such as higher rates of KTH injuries in males than females. Better fidelity for lower-speed crashes than higher-speed were demonstrated through risk equations.
