Resumen del estudio

Forty-eight patients with anterior cruciate ligament (ACL) rupture and high-grade pivot shift were randomized to receive ACL reconstruction combined with either lateral extraarticular tenodesis (LET) or anterolateral ligament (ALL) reconstruction. The primary outcome of interest was the Tegner-Lysholm Knee Score. Secondary outcomes included pivot shift test, Lachman test, and failure rate. Outcomes were assessed preoperatively and at two years postoperatively. Overall, the results of the study revealed that both groups demonstrated significant improvement in functional scores and knee stability, with no statistically significant differences between groups at two years. These findings suggest that both augmentation techniques are effective, although neither showed clear superiority in clinical outcomes.
