As Rooney pointed out, the knee joint experiences some small rotation as it
takes on weight bearing load. Otherwise, any rotated appearance is due to
developmental deformation of the cannon bone and cannot be manipulated. Only
in severe knee injuries do the bones of the knee move in such a way as to be
considered "rotated"--that is, the joint is falling apart and the animal is
doomed.
This vet says that eliciting a nice "pop" from the knee is easy, akin to
popping your fingers.
He says that it's unbelieveable to him how many reasonably sane people will
go through a half dozen quacks (my word--he said something else that I can't
remember) before finally stumbling back to reality in attempts to solve
difficult problems in horses. He said there is a certain group of
practitioners who have come upon the realization that "if it isn't there, you
can cure it!"
He also pointed out that, with a certain high suspensory ligament injury he's
found that rubbing it for a few minutes gets rid of the lameness caused by it
instantly, sometimes for days--but then it's back. He says there are probably
dozens of tricks like this that help with pulling he wool over the eyes of
the unsuspecting.
He'd never heard of knee realignments and was very surprised the technique
was making its way through the ranks of his favorite folks, endurance riders.
