Fig. 2From: Morphological study of the vastus medialis oblique in recurrent patellar dislocation based on magnetic resonance imagesThe measurement of muscle fibre angulation and craniocaudal extent of the VMO in the control and recurrent LPD groups. a, d Images showing the plane in which the “Roman arch” was most obvious; the longitudinal axis of the femoral shaft was identified; b, e The adductor tubercle was located in the medial margin of the femur in the transverse slice; the red dots indicate the lowest point of the VMO, and the VMO muscle-fibre angulation in the controls and LPD patients were 20.49° and 46.79°; e, f The magnitudes of craniocaudal extent of the VMO in the controls and LPD patients were 27.57 mm and 12.65 mm, respectivelyBack to article page
