I got to the barn the other night to bring the boys in and arrived to quite a mess! My older horse had kicked one of the boards in half, wich I'm assuming was what cut the inside of my younger guy's front right leg (A 2x2 inch "L" shaped gouge about 6 inches above his front right inner knee) when the board kicked out. It could've used a stitch at the time, however it was too late as the wound had already started to heal by the time I was cleaning it out. I hosed his leg down, (he was sound) noticed some slight swelling around the cut itself, put some vitamin E on it and put him in the barn for bed. The next morning it had swollen more, but not to the front of the knee, and he was clearly in discomfort when I touched it. I cold hosed, walked, put Derma Gel on it and gave him half a small scoop of bute with his dinner as he was in pain with just a gentle touch and compensating for it when he walked. Anyways, this brings me to yesterday afternoon about 3 pm, almost 24 hours since the bute, (I had noticed he was feeling much more comfortable that morning), and the wound itself is looking great, healing up beautifully nice and clean, but he now has a fluid-filled sac on the front of his knee and warm swelling down the inside of the leg. I cold hosed and walked him, the swelling went down, but the sac on the knee did not. I am ready to call my vet for a second opinion, but thought I'd give a post on here a shot in the meantime. Please let me know if anyone has encountered this problem, what your diagnosis was and treatment!! Just want to see my lil man back in action! Thank you!!
