Fig. 2From: Biomechanical analysis of canine medial patellar luxation with femoral varus deformity using a computer modelThe 3D patellar displacement with a millimeter scale. The x, y, and z-axes represent the mediolateral, craniocaudal, and proximodistal directions, respectively. The black marks grouped together represent the route of relatively stable patella (at aLDFA values ranging from 95° to 102°), while the other colored marks scattered in the craniocaudal and medial directions represent patella at aLDFA values ranging from 103° to 110°. The medial direction of the 3D coordinate graph was represented by the blue surfaceBack to article page
