Morphometric risk factors effects on anterior cruciate ligament injury

Abstract

Objectives This study aims to compare the morphometric differences between patients with and without an anterior cruciate ligament (ACL) injury and to investigate the anatomical risk factors associated with ACL injury. Patients and methods Between February 2020 and February 2022, a total of 100 patients (57 males, 43 females; mean age: 36.2±6.8 years; range, 18 to 45 years) who were operated for isolated non-contact ACL tear as the patient group and a total of 100 healthy individuals (58 males, 42 females; mean age: 35.0±6.9 years; range, 18 to 45 years) without an ACL tear as the control group were included. Magnetic resonance imaging scans of the knee joint were included in the study. Morphological variables of the ACL, distal femur, proximal tibia, and menisci were measured. Results The mean ACL inclination angle and medial meniscus bone angle were 37.7±3.8 and 20.2±2.9 in the patient group and 48.1±3.3 and 25.0±2.9 in the control group. According to the results of multivariate analysis, those with small ACL inclination angle and medial meniscus bone angle were more likely to have ACL tear (odds ratio: 0.128, intraclass correlation coefficient: 0.038-0.430, p=0.001). Conclusion Small ACL inclination angle and medial meniscus bone angle can be a risk factor for ACL tear.

The risk factors for second anterior cruciate ligament (ACL) tear after ACL reconstruction

“…Small ACL inclination angle and medial meniscus bone angle can be a risk factor for ACL tear. [ 5 ] Medial meniscus posterior base angle and the lateral meniscus posterior base angle values above 84.5º and 93.15º, respectively are new indirect magnetic resonance imaging findings of ACL injury.
