Several biomechanical studies have demonstrated the
importance of the anterolateral ligament (ALL) in rotational instability of the knee.1,10,12,14 Despite this, the precise role of the ALL in eliminating the pivot shift remains
controversial.9,11,13 This disparity exists secondary to the
nature of cadaveric research and the subsequent creation of
artificial injury patterns that are not a true representation
of in vivo characteristics. This case report provides clinical

Purpose of this paper is to provide an overview of the latest research on the anterolateral ligament (ALL) and present the consensus of the ALL Expert Group on the anatomy, radiographic landmarks, biomechanics, clinical and radiographic diagnosis, lesion classification, surgical technique and clinical outcomes. A consensus on controversial subjects surrounding the ALL and anterolateral knee instability has been established based on the opinion of experts, the latest publications on the subject and an exchange of experiences during the ALL Experts Meeting (November 2015, Lyon, France).

To evaluate the reliability of the Iliotibial band compared to gracilis tendon as a graft to be used in anterolateral ligament reconstruction.
METHODS:

The results of anterior cruciate ligament reconstruction (ACLR) are widely recognized to be satisfactory on the basis of outcome measures such as the International Knee Documentation Committee (IKDC) and Lysholm scores. However, there is moderate variation among several series of different techniques. For example, Hussein et al showed a range of residual pivot, from 7% to 33%, depending on the technique used. Furthermore, up to 30% of patients in contemporary series can still experience persistent instability, and only 65% to 83% can return to the preinjury level of sport.

Background: The anterolateral ligament (ALL) has been identified as a structure on the lateral side of the knee, but debate exists regarding whether it is a capsular thickening or a ligament. Hypothesis: A detailed ultrastructural characterization of the ALL and its ultrastructure collagen arrangement will reveal it more closely resembles ligamentous tissue than joint capsule. Study Design: Descriptive laboratory study. Methods: Eight paired knee samples from 4 fresh-frozen male cadavers were used for this study.

Background: Combined anterior cruciate ligament (ACL) and anterolateral ligament (ALL) reconstruction is associated with improved clinical outcomes as compared with isolated intra-articular reconstruction, but the indications are not precisely defined. It may be the case that patients with proven anterolateral injury on preoperative imaging are most likely to benefit, but the accuracy of magnetic resonance imaging (MRI) is not known. Purpose/Hypothesis: To evaluate the correlation between MRI and surgical exploration in acute ACL-injured knees.
