27 In addition, several authors have pointed out that the effect on anterolateral rotatory instability might not be significant because the ALL acts mainly during knee flexion. 21 , 25 , 43 Nevertheless, recent clinical studies have shown that combined ACL and ALL reconstruction improves residual anterolateral rotational instability. 23 The pivot-shift mechanism can be explained by 2 factors.
