Even a passing acquaintance with the sport pages makes one aware that the knww of an athlete is quite vulnerable to injury particularly in football. Most discussions center around ligamentous injury and internal derangements in professional and college athletes. One might assume that the high school athlete or adolescent would be susceptible to these same injuries; however, the adolescent knee may react differently to the same stresses. Forces that would result in a ligamentous injury in an adult are likely to result in an epiphyseal injury in a child or adolescent. THe most common cause of a ligamentous injury or epiphyseal separation of the knee is a valgus stress, a force applied on the lateral surface of teh knee. This most commonly results from a so-called "clipping" injury in football, when a p-layer is blocked or tackled from the lateral side at the knee with the foot firmly implanted. IN an adult, this valgus force results in a strain or rupture of the medial collateral ligament. In an adolescent, the valgus force may be transmitted through the medial collateral ligament onto the distal femoral epiphysis or, less commonly, the proximal tibial epiphysis with a resultant epiphyseal separation ...
