Ipsilateral diaphyseal femur fractures and knee ligament injuries.
Three hundred and nine consecutive patients with 320 diaphyseal femur fractures were retrospectively reviewed to determine the incidence of ligament injury in the ipsilateral knee. Ligamentous injuries were diagnosed if serious (Grades II and III) instability was apparent on admission, found at surgery for femoral stabilization, or disclosed on roentgenograms during closed management. Seventeen patients with unilateral shaft fractures of the femur had ipsilateral knee ligament injuries, or 5.3%. There was no relationship between specific ligament damage and the cause of the injury or level of fracture. Twelve patients were followed for an average of 34 months. Five patients lacked full extension and ten lacked full flexion. Two of seven patients with ligament repair and three of five patients without ligament repair had at least one unstable ligament. Better range of knee motion was obtained when both the femur and ligament injuries were surgically managed, but most (seven of 12) patients were disabled.
