Comet was diagnosed with end stage osteoarthritis. It is both incurable and it is chronic. He has bone on bone rubbing and heavy cartilage damage. Lots of inflammation as well. He also has bone spurs as a result of the arthritis. ALL of this was caused by racing. We were going to inject him but he has been injected so many times during his racing career that it stopped working for him. He can be ridden walk trot. It won't hurt him to be ridden because the damage is already done. Where he is older, it will help him to keep him moving. His stifle(s) are so bad that if he was a human, he would need a knee replacement. His arthritis is going to just get worse and worse. Only thing we can do is give him lots and lots of love, peace, and try to give him comfort.
In the X ray photo : The gap in the blue area is cartilage. There is only a little left. The gray area in the green circle is inflammation. The red ring shows where there should be cartilage. In that area, there is bone on bone. In the pink ring, there are several bone spurs. Where the cartilage is worn off, there is pain. The body tries to heal itself by immobilizing the joint by trying to calcify it. The joint is so large that it is impossible to immobilize so that is where the bone spurs come from
