Investigating Concussion Knowledge in US Born Versus Internationally Born Collegiate Student-Athletes in the United States.

Objective: To compare concussion knowledge between US born and internationally born collegiate student-athletes. Furthermore, to investigate whether length of time in the United States impacted concussion knowledge.

Design: Survey.

Prevalence and location of bone bruises associated with anterior cruciate ligament injury and implications for mechanism of injury: a systematic review.

Background: Bone bruising is commonly observed on magnetic resonance imaging (MRI) after non-contact anterior cruciate ligament (ACL) injury.

Objectives: The primary objective of this study was to determine if the location and prevalence of tibial and femoral bone bruises after ACL injury can be explained by specific injury mechanism(s). The secondary objective was to determine whether the bone-bruise literature supports sex-specific injury mechanism(s).
