Anterior Cruciate

AbstractTears of the anterior cruciate ligament (ACL) are common and represent a serious injury. Although diagnosis on magnetic resonance imaging (MRI) is usually straightforward, diagnostic difficulty can occasionally arise. This review provides tips for imaging the ACL in those scenarios where a confident diagnosis is not possible on standard MRI of the knee. Potential pitfalls while imaging the ACL are also discussed.

Femoral Notch

Background Research has shown that variations in femoral intercondylar notch morphometry may be a predisposing factor for noncontact anterior cruciate ligament injury. Hypothesis There are anatomic differences in the anterior cruciate ligament and femoral notch between men and women. Study Design Descriptive anatomic study. Methods Using magnetic resonance imaging, we performed a three-dimensional analysis of the femoral intercondylar notch morphometry to look for differences in femoral notch and anterior cruciate ligament volumes between men and women. Axial plane magnetic resonance imaging scans were performed on 96 knees in 48 asymptomatic subjects. Digital measurements were taken of femoral notch area, anterior cruciate ligament area, notch width, and bicondylar width, within defined parameters of the femoral notch. The notch and anterior cruciate ligament volumes were then calculated. Analysis of variance was performed using sex, height, and weight as covariates. Results The volume of the femoral notch was found to be statistically smaller in women compared with men; this difference was primarily related to height. A similar relationship was found for anterior cruciate ligament volume. A statistically significant correlation was found between femoral notch volume and anterior cruciate ligament volume; patients with smaller notches also had smaller anterior cruciate ligaments. Conclusions Our results suggest that there is a difference in femoral notch and anterior cruciate ligament volume between men and women, which, in turn, is related to differences in height and weight.

Purpose: To evaluate the three standard orthogonal imaging planes and a paracoronal imaging plane for anterior cruciate ligament (ACL) tears. Material and Methods: Ninety patients (91 knees; 29 F and 61 M) aged between 15 and 84 years (mean 36.9±16.4 years) underwent magnetic resonance imaging (MRI) of the knee prior to arthroscopy. At surgery, 32 knees had an intact ACL, 4 a partial tear, and 55 a complete ACL tear. In all patients, axial, sagittal, coronal, and paracoronal T2-weighted turbo-SE images were acquired. The ACL was classified as intact, partially, or completely torn. Partial and complete tears were combined for statistical evaluation. Results: Partial ACL tears (four cases) were not correctly diagnosed at MRI except in one knee by one observer on coronal images. Sensitivity in detecting ACL tears was 95%/63% (reader1/reader2) in the axial, 93%/95% in the sagittal, 93%/86% in the coronal, and 100%/93% in the paracoronal plane. Specificity was 75%/81% in the axial, 72%/81% in the sagittal, 78%/94% in the coronal, and 78%/88% in the paracoronal plane. Conclusion: ACL tears can be diagnosed accurately with each of the standard orthogonal planes. Based on reader confidence and interobserver agreement paracoronal images may be useful in equivocal cases.
