3D patellar motion at walk. a) sum between the patellar translation due to the rotation around the Z axis and the translation along the Y axis. b) sum between the patellar translation due to the rotation about the Y axis and the translation along the Z axis. c) sum between the patellar translation due to the rotation about the X axis and the translation along the Y axis. Renderings d, e, f based on scientific rotoscoping at selected timepoints. d) maximal MPL after TO. e, f) Distal-proximal position of the patella at TD. Each curve represents the mean of the strides analyzed per dog (blue: dog 1, bright green: dog 2, magenta: dog 3, cyan: dog 4, red: dog 5, black: dog 6). Vertical dotted lines indicate toe-off. Note that the patella is more distally placed in the dog with MPL. Black and cyan lines correspond to dogs without patellar luxation. Red, magenta, and blue lines correspond to dogs with MPSL. The bright green line corresponds to the dog with MPPL
