Summary

The goal of this \[type of study: observational study\] is to \[detect concomitant KF and ALL injury in knees with ACL injury using MRI in both adult and pediatric patients and compare the effect of KF injury and multiple risk factors (concomitant injury to the ALL, medial collateral ligament \[MCL\], or anterior, central, or posterior part of the medial or lateral meniscus) on anterolateral rotatory laxity as measured by the pivot-shift test in a clinical setting.\]. The main question \[s\] it aims to answer are: \[Does the main risk factor for a high-grade pivot shift after acute ACL injury differ between pediatric patients and adults?\] \[Does Concomitant KF injury significantly affect the pivot-shift phenomenon in pediatric patients with acute ACL injury?\] Researchers will compare \[71 pediatric patients and 469 adults\] to see if \[main risk factor for a high-grade pivot shift after acute ACL injury differs between pediatric patients and adults?\].

Conditions

• ACL-injury

Interventions

Type	Name	Description
OTHER	Age	The retrospective study included 540 patients with primary ACL tears (71 pediatric patients and 469 adults) whose MRI examination and pivot-shift test were conducted within 14 days after injury. To detect concomitant KF and ALL injury in knees with ACL injury using MRI in both adult and pediatric patients and compare the effect of KF injury and multiple risk factors on anterolateral rotatory laxity as measured by the pivot-shift test in a clinical setting.
