Ok, she told me he actually does have a diagnosis. Upward fixation of the patella. She is doing a round of injections(of what I don't know but am gonna see her in an hour and will ask) and going to get him corrective shows next month.

I don't know how corrective shoes would do anything here. I assume that's what you meant by "corrective shows." A good trim yes, but not shoes unless there is something else going on.

There are recommendations for physical therapy of this condition. Hopefully Vidaloco will see this thread and post -- she also has a young horse with this problem.
