60 patients with anterior cruciate ligament (ACL) ruptures were randomized to receive repair based upon theanteromedial bundle (AM), posterolateral bundle (PL), or double bundle (DB) reconstruction. The results of this study indicated that there were no differences in the Lysholm scores or Tegner scores between all three groups. However, patients who received DB reconstruction had significantly greater anterior stability of the knee and higher negative rates of pivot tests in comparison to PL based reconstruction (P<0.05). Lastly, patients who received DB reconstruction had significantly greater extensor muscle strength in comparison to those who received AM based reconstruction (P<.05).
