Lateral Extra-articular Tenodesis Restores Knee Rotational and Translational Stability Regardless of Fixation Type: A Matched-Pair Cadaveric Study

The authors aimed to compare the biomechanical stability of the knee using three different fixation methods for lateral extra-articular tenodesis (LET) during anterior cruciate ligament reconstruction. Their findings indicated that all fixation methods—suture anchors, interference screws, and metallic staples—restored knee rotational stability effectively, even after cyclic loading, although suture anchors showed greater vulnerability to cyclic stress compared to the other methods. Ultimately, all three fixation techniques are considered viable options for LET, with no significant differences in overall stability observed between them in a controlled laboratory setting.
