10mo MC Labrador cross with bilateral pelvic limb deformities and abnormal gait (a). Radiographs reveal a complex angular and
rotational deformity of the right pelvic limb centered on the stifle joint. A small osseous body dorsal and medial to the distal femur
represents the hypoplastic patella (b,c: arrow). Images d and e show the angular and rotational deformities in three dimensions.
Image f shows the distal femur in isolation and highlights the misshapen and hypoplastic trochlear ridges (f: arrowheads). The patella
is not included in the 3D renderings.
