“…Conversely, in the normal meniscus, free hydrogen ions are lacking, and low-intensity signals are present in the MRI scanning sequence (Crues et al, 1987;Englund et al, 2008). Meniscus injury types mainly include bucket handle tear (the lack of normal meniscus morphology at the sagittal site, and the injured meniscus can migrate into the intercondyloidea fossa), level tear (a tear parallel to the tibial plateau appears in the layer), oblique tear (the most common type, in which the strip tear and the tibial plateau form a certain angle), radial tear (the tear has a radial shape), and compound injury (all of the above manifestations appear as a compound injury (Jee et al, 2003;Van Dyck et al, 2007;Long et al, 2010), and the local interface signal contrast is obvious).…”

ABSTRACT. This study aimed to verify the accuracy of lowfield-intensity magnetic resonance imaging (MRI) in diagnosing meniscus tears. A total of 171 patients were examined through low-field-intensity MRI to detect meniscus injuries. These patients were then diagnosed through arthroscopy. Examination results were recorded and compared. The accuracy of the diagnosis for internal and external meniscus tears through low-field-intensity MRI was 95.91% and 95.91%, respectively, the sensitivities were 95.60% and 96.47%, respectively, and the specificities were 96.25% and 95.35%, respectively. Low-field-intensity MRI is an accurate and cost-effective method for diagnosing meniscus tears.

“…Pre-operatively, surgeons need to acquire information not only on the presence of the meniscal tears but also on their morphological characteristics, in order to decide the most appropriate surgical method (resection or suturing of the torn menisci) [4,7,8,20]. Axial images of the menisci may help in identification and confirmation of the meniscal tear patterns [18].…”

“…The four main approaches for management of meniscal tears are: partial meniscectomy, meniscal repair, conservative treatment and complete meniscectomy [7]. There are various factors that influence the treatment of meniscal lesions such as the patient's age, chronicity, lesion type, location of the lesion relative to the vascular zone and size of the tear [4].…”

Objective: To evaluate the diagnostic efficacy of thin-slice (1 mm) axial proton density-weighted (PDW) MRI of the knee for meniscal tear detection and classification. Methods: We prospectively assessed pre-operative MR images of 58 patients (41 males, 17 females; age range 18-62 years) with arthroscopically confirmed meniscal tear. First, we evaluated the performance of the sagittal and thin-slice axial MR images for the diagnosis of meniscal tears. Second, we compared the correlation of tear types presumed from sagittal and axial MRI with arthroscopy and tear classification from axial MRI. Tears were classified on the sagittal plane and the axial plane separately. The diagnostic performance and tear classification were compared statistically with arthroscopy results, which is accepted as the standard of reference. Results: 8 of 58 patients were removed from the study group because they had complex or degenerative tears. A total of 62 tears were detected with arthroscopy in 50 patients. On the sagittal images, sensitivity and specificity values were 90.62% and 70.37%, respectively, for medial meniscus tears and 72.73% and 77.14%, respectively, for lateral meniscus tears. The corresponding values for axial images were 97.30% and 84.00%, respectively, for medial meniscus tears and 95.65% and 80.50%, respectively, for lateral meniscus tears. There was no significant difference in tear classification between the arthroscopy results and the thin-slice axial PDW MRI results (p.0.05). Conclusion: thin-slice axial PDW MRI increases the sensitivity and specificity of meniscal tear detection and especially classification, which is important for surgical procedure decisions.
