In Vivo Length Changes of the Anterolateral Ligament and Related Extra-articular Reconstructions
Conclusion:
An anatomic ALL reconstruction as modeled based on recent anatomic studies was not isometric during in vivo knee flexion and was not affected by ACL deficiency. The nonanatomic extra-articular reconstructions demonstrated more biomechanically favorable length change patterns with the smallest percentage increase in elongation during knee flexion.
Clinical Relevance:
This study presents the first in vivo biomechanical data on the ALL, in both healthy and ACL-deficient knees, and provides surgical information that may be valuable for restoring normal anterolateral stability.
