The common afflictions of the knee due to athletic injury are a matter of serious concern to physicians. It is estimated that the cost of sports related injury in 1974 was 40 billion dollars. Knee injury has always been a source of concern to the public. The magnitude of this cost has been a major stimulus to the development of sports medicine as a social science. Football coaches at the professional, college, and high school levels have modified their rules in an attempt to minimize these injuries. Much more needs to be done.

In sports the knee serves a number of functions. It provides the needed balance for support, agility, and precise activity. The knee also transmits incredible forces for acceleration and deceleration in the propulsive mechanisms required to perform sports motions, with both speed and strength. Cybex data that we have accumulated show routinely that in pathologic knee conditions deficits of 10 per cent and more occur in the strength of the involved extremity in hip abduction as well as in thigh flexion and knee extension. Sites far removed from the site of the knee disorder can be afflicted in this manner.
