“…Discoid lateral meniscus (DLM) of knee joint is a fibrous cartilage with abnormal morphology and structure 1 , divided into complete, incomplete and Wrisberg 2 , affecting 0.4%-5% Western population and >16% Asian population 3 , which is symptomized by pain, swelling, snapping, buckling and locking 4 , seriously impacting the patients' quality of life.…”

“…Previous studies have reported that many radiographic parameters, including a widened lateral joint line, cupping of the lateral tibial plateau, squaring of the lateral femoral condyle, an elevated fibular head and a condylar cut-off sign, are useful and convenient for DLM screening [2,[7][8][9][10][11][12]. Arthroscopic visualization and MRI parameters are also utilized in DLM screening [6,[21][22][23]. All these parameters originate from the hypoplasia of the lateral tibial plateau and the lateral femoral condyle related to DLM.…”

Background Many studies have shown that hypoplasia of knee bone morphology is related to the morphological features of the discoid lateral meniscus (DLM). However, few studies have focused on hypoplasia of tibial eminence morphology in juvenile patients with complete DLM. The purpose of this study was to determine the relationship between tibial eminence morphology characteristics and complete DLM in juvenile patients. Methods The DLM group comprised 34 juvenile patients with complete DLM, and the control group comprised 34 juvenile individuals, each with a normal lateral meniscus based on magnetic resonance imaging (MRI) findings. All parameters, including tibial width (TW), tibial eminence width (TEW), the height of the lateral tibial spine (HLTS), the height of the medial tibial spine (HMTS), lateral slope angle of the lateral tibial eminence (LSALTE), lateral slope angle of the medial tibial eminence (LSAMTE), tibial eminence width ratio (TEWR), height of the lateral tibial spine ratio (HLTSR), and the height of the medial tibial spine ratio (HMTSR), were recorded using coronal MR images. Statistical analyses were used to determine the differences between the two groups and whether differences were significant. Results The TEW and TEWR were significantly greater (P < 0.05), and LSALTE and LSAMTE were significantly smaller (P < 0.05) in patients in the DLM group than in participants in the control group. Receiver operating characteristic (ROC) analysis revealed that a larger TEW, above 13.4 mm, was associated with complete DLM, with a sensitivity of 77.0% and specificity of 88.2%, and a larger TEWR, above 19.7%, was associated with complete DLM, with a sensitivity of 76.5% and specificity of 91.2%. Conclusions MR imaging can be used to diagnose tibial eminence hypoplasia in juvenile patients with complete DLM. Additionally, TEW and TEWR could help clinicians screen for complete DLM in juvenile patients.

Conclusions: This study recognized hypoplasia of tibial eminence morphology in juvenile patients with complete DLM using coronal MRI scans. Additionally, TEW and TEWR could help clinicians screen for complete DLM in juvenile patients.
