Zhang C, et al. - A total of 200 participants were examined to evaluate the 2-dimensional (2D) femoral notch parameters like the notch width (NW) and notch width index (NWI) vs the 3-dimensional (3D) notch volume based on magnetic resonance imaging (MRI) determining appropriate femoral parameters for anterior cruciate ligament (ACL) injuries. They noted weak associations between the 2D parameters and the 3D volumes. They observed the following factors as predictable parameters to the risk of ACL injuries: the notch volume and the NW at the popliteal groove, notch inlet, and ACL attachment.
