The anterolateral soft tissue structures (ALC) of the knee include from superficial to deep: the iliotibial band (ITB) with its superficial, middle, deep (including Kaplan fibers) and capsulo-osseous layers, the anterolateral ligament (ALL), the anterolateral capsule and the lateral meniscus.61
Anterolateral rotational knee stability is maintained by the ACL and the ALC of the knee. The ACL is the primary restraint to tibial anterior translation (mainly by the AMB, at higher knee flexion angles) and internal rotation (mainly by the PLB, at lower flexion angles especially in or near full extension). While the ALC, mostly the deep ITB including Kaplan fibers, is the primary restraint to internal tibial rotation at higher flexion angles.61,63
Anterolateral rotational knee instability (ALRI) is a combined anterior translational and internal rotational movement of the proximal tibia. It occurs either due to acute combined injury to the anterior cruciate ligament (ACL) and the anterolateral soft tissue structures (ALC) of the knee or by progressive elongation of the other ligamentous restraints to internal rotation in chronic ACL deficiency.1
Persistent ALRI is considered one of the commonest causes of ACLR failure even after adequate anatomic SB- or DB-ACLR due to non-addressed anterolateral structures injuries95 or other associated factors as younger ages, female sex, increased BMI, genu recurvatum, generalized ligamentous hyperlaxity, increased posterior tibial slope.207 So a lot of studies have discussed the role of ALC reconstruction either non-anatomic by LEAT or anatomic by ALLR in addition to anatomic SB-ACLR in controlling ALRI.61,225,250
This study included 30 cases with high risk for ALRI of different operative indications as pivot shift test grades 2 and 3, young ages < 25 years old, active females, obesity with BMI ≥ 35, participation in pivoting sports, chronic injuries > 12 months, generalized ligamentous hyperlaxity, genu recurvatum > 10º, Segond fracture, and revision ACLR.
