You might presume, as I did, that Polyboroides has a unique sort of intertarsal joint, perhaps with the trochlear surfaces of the distal tibiotarsus wrapping onto the posterior surface of the bone as well as the anterior surface.
The researchers concluded that the VMO is indeed an important stabilizer of the patella in the trochlear groove.
Whereas the olfactory and optic nerves are sensory and the oculomotor and trochlear nerves are motor; the trigeminal nerve is a mixed nerve, containing both sensory and motor fibers, each attached to the pons by a separate structure.
-- Two forms of true patellar luxation in the horse may be considered; one which is due to the patella becoming fixed upon the internal trochlear rim of the femur and the other when the patella slips over the outer rim of the trochlea.
Traction is exerted upon the rope and at the same time force is directed against the stifle joint to produce further extension if possible, so that the straight patellar ligaments may relax sufficiently to allow the patella to be dislodged from its position upon the inner trochlear lip.
When the patella is situated upon the inner trochlear rim, the tibia must be extended because of the traction exerted by the straight ligaments.
The outer trochlear rim being the smaller of the two, inward luxation does not occur in the horse.
_Outward luxation of the patella_ is occasioned by a lax condition of the internal femeropatellar ligament or a rupture of the same so that the patella slips over the outer femoral trochlear rim and permits of an abnormal flexion of the stifle joint.
It then runs forward on the lateral side of the calcaneus, above the trochlear process and the tendon of the Peronæus longus, and is inserted into the tuberosity at the base of the fifth metatarsal bone, on its lateral side.
The tendon then extends obliquely forward across the lateral side of the calcaneus, below the trochlear process, and the tendon of the Peronæus brevis, and under cover of the inferior peroneal retinaculum.
