Dr. Christian Balldin on Rams QB Sam Bradford’s Torn ACL

The quarterback for the St. Louis Rams, Sam Bradford, tore his Anterior Cruciate Ligament (ACL) this past weekend, ending his current season.  Unfortunately, ACL tears are a common injury in sports like football that have significant pivoting and change of direction as part of the game.  They can occur as part of a traumatic injury (where the knee is put in an unnatural position and the ligament tears due to excessive force applied to the knee) or as part of a non-contact pivoting injury, which is actually the most common mechanism of injury.
