Hello everyone, My 16 year old Thoroughbred gelding, had an injury many years ago, before I bought him. His right front leg was the one affected by the injury and as such, the knee became arthritic. He is a great jumper and I have jumped with him numerous times, over both low and high obstacles (gradual build up) and he seems to show no pain, heat or lameness in this leg before, during or afterwards (I always make point of it to check). I can count on one hand, how many times he has shown lameness, but I know the causes for all those times and he recovered fully. One thing I should mention though is, when he's standing absolutely still, it is evident that he doesn't put any weight on that leg. This you can see by his body and the form at which the hoof on that leg grows. Also he has more difficulty cantering on one lead than the other. My farrier tells me, this could be due to the arthritic knee. Regardless of whether or not he's showing pain, am I doing him more harm jumping him, knowing he has arthritis? Or should he be fine? Cheers.
