Background: Lower extremity injuries are frequently observed in car-to-pedestrian accidents and due to the bumper height of most cars, knee joint is one of the most damaged body parts in car-to-pedestrian collisions.Objective: The aim of this paper is first to provide an accurate Finite Element model of the knee joint and second to investigate lower limb impact biomechanics in car-to-pede...

BACKGROUND Limited knowledge exists on injuries among professional alpine skiers. OBJECTIVE To describe the risk of injury and the injury pattern among competitive World Cup alpine skiers during the competitive season. METHODS Retrospective interviews were performed with all World Cup athletes from 10 nations at the end of the 2006-7 and 2007-8 winter seasons, and all acute injuries occurri...

BACKGROUND About 12% of patients who have undergone primary anterior cruciate ligament (ACL) reconstruction sustain a contralateral ACL injury within 5 years. PURPOSE To investigate patient-reported knee function, quality of life, and activity level in patients with bilateral ACL injuries. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A search of hospital records identified 147...

BACKGROUND In sports involving pivoting and landing, female athletes suffer knee injury at a greater rate than male athletes. HYPOTHESES Proprioceptive deficits in control of the body's core may affect dynamic stability of the knee. Female, but not male, athletes who suffered a knee injury during a 3-year follow-up period would demonstrate decreased core proprioception at baseline testing as ...

The effects of immobilization on both the circumferential dimensions of the lower limb, and the passive resistance of the knee to sinusoidal motion in the flexion-extension plane, were studied in patients immobilized after tibial fractures or ligamentous injuries of the knee. Immobilization resulted in a decrease of circumferential dimensions of the lower limb, indicating atrophy of thigh and c...
