Abstract

Knee joint injuries were found in 214 out of 357 fatal pedestrian victims of traffic accidents (60%). The cross-sections of tibial and femoral epiphyses revealed bone bruises (due to compression and avulsion) and the percentage of victims with knee injuries increased to 80% (in the group of lateral impacts - 94%). The bone bruises in the central tibial and femoral condyles were observed only in victims hit in an upright position. There was a strong correlation between the side of impact on the extremities in medium sized pedestrians (from the front, back, lateral and medial side) caused by passenger cars and the mechanism of knee injuries (hyperextension, anterior dislocation of the proximal tibial epiphysis in relation to the femoral condyles, valgus and varus flexion). In the cases of very low impacts (e.g. in very tall victims hit by rapidly breaking wedge-shaped cars) or very high impact (e.g. in very short victims or truck hits) the "reversed" complexes of injuries were found (lever principle). These findings showed that knee joint injuries are useful for determining the car-pedestrian location on collision and the type of vehicle (in hit-and-run accidents).
