Several biomechanical studies have demonstrated the
importance of the anterolateral ligament (ALL) in rotational instability of the knee.1,10,12,14 Despite this, the precise role of the ALL in eliminating the pivot shift remains
controversial.9,11,13 This disparity exists secondary to the
nature of cadaveric research and the subsequent creation of
artificial injury patterns that are not a true representation
of in vivo characteristics. This case report provides clinical
evidence of the important role that the anterolateral structure plays in anterolateral rotational instability, as demonstrated by the pivot-shift sign.
