PURPOSE: @entity509 of the lateral femoral condyle has been reported in discoid lateral meniscus @entity1 , but associated imaging findings in the axial plane have not been characterized. In this study, we aimed to identify differences in the lateral femoral condyle between @entity1 with discoid lateral meniscus and those with normal menisci using axial MRI images. METHODS: Twenty-three @entity1 (24 knees) with @entity9821 , 43 (45 knees) with @entity9821 , and 50 with normal menisci (50 knees) were enrolled and distributed into three groups. Two new angles, posterior lateral condylar angle (PLCA) and posterior medial condylar angle (PMCA), were measured on axial MRI images; the posterior condylar angle ( @entity4901 ) was also measured. Differences between the three groups in the PLCA, PMCA, @entity4901 , and PLCA/PMCA were analysed. The predictive value of PLCA and PLCA/PMCA for @entity9821 was assessed. RESULTS: In the @entity9821 group, PLCA and PLCA/PMCA were significantly smaller compared with the normal meniscus group and the @entity9821 group (P  <  0.001). A significantly larger @entity4901 was identified in the @entity9821 group compared with the @entity9821 group (P  <  0.05) and normal meniscus group (P  <  0.05). Both PLCA and PLCA/PMCA showed excellent predictive value for @entity9821 . CONCLUSIONS: @entity509 of the posterior lateral femoral condyle is typically seen in @entity1 with @entity9821 . PLCA and PLCA/PMCA can be measured from axial MRI images and used as excellent predictive parameters for @entity9821 . LEVEL OF EVIDENCE: Diagnostic study, Level III.
