I have a 4 year old OTTB gelding who has what the vets call Upward Fixation of the Patella. This is where his stifles lock and he has to take an akward step and pop his leg, to unlock himself. Its a really strange sight.
This link is to a video of what it looks like. The horse is this video has it way worse than my gelding. And there are three common ways to fex this.
1. Hill work and work in the sand in hope that the thigh muscle will build up and the problem will fix itself.
2. Go in with a large needle and create scar tissue in the ligiment that is catching on the patella.
3. Completly cut the ligiment that is catching and fix it to a better location.
My vet checked him and he said that I could still ride him, but that jumping was not advizable. So I stopped jumping him and worked on our flat work. His stifles stopped locking!
So what I did to test a theroy of mine is, I hopped him over a few little (smaller than 2 foot) jumps to see if the next day he came out with locking stifles. Sure enough, I brought him out of his stall the next day and his stifles were locking.
Is this normal? I mean do stifles lock only when doing certain activites? Like Jumping? I bought him so that he could be my low level eventer so weither or not this is normal, I will be fixing it. I'm just not sure how yet.
Any advice would be great.
