That is exactly what my vet said doing cavalettis would do. You are forcing the horse to lift that leg, rather then swing it out to avoid bending it.
But one difference in what you are saying vs. what she said. She said we need to "tightening" the ligement and build the muscles. The reason it is locking is the ligaments have slack in them and the muscles are not strong enough to hold the patella (knee cap) in place.
That is why she said if the exceriseing doesn't work she would then try blistering the ligement to create scar tissue to tighten it up.
Last resort is clipping it, which she said she does not like to do.
What do you think??? Sound right or have you heard they need to be "loosened up"??

I will defer to your vet.... Her explanation of what is going on makes sense. And I think we will set up some cavaletti for Cyn as well, for something to do with her here at home.
