My 2 and a half year old QH colt injured himself LAST spring by sticking his leg through the top 2 bars of a tube gate, then falling over with it still in the gate. Until recently he was only having intermittent "swelling" of his left knee (see photo below), but now it's always big. Actually, it's not really a swelling, per se, it's more like a synovial fluid filled balloon just under the skin between the bone ends. This doesn't bother him in any way, shape, or form. You can poke, prod, and push on the bump of fluid all day long. He's never been lame and he has full range of motion in the joint. It's never been hot, and the surrounding joint area has never swelled.
The vet said not to worry, try cold hosing it twice a day and to give it some time. Since he was only a yearling, he had the entire year just to grow and relax...and the swelling would come and go. This past spring, since his knee was still swelling, the vet recommended banamine once daily for 5 days and to give him an oral glucosamine/chondroitin/msm supplement. Since the swelling isn't from inflammation, the banamine had zero affect on it.
I would really like to show him in halter this coming summer. I was told that with his knee being like this, halter is definitely out. Other than being horribly hideous to look at, it doesn't appear to be a problem for him, but I worry that as I begin to trail ride and compete (I am an avid team sorter) with him it may begin to lead to calcification, adhesions, and/or arthritis....or worse.
Does anyone have any ideas or experience with this? I would SO appreciate any help y'all might have to offer!
