These photos are a couple of months old, but they were the best leg shots I could find. I asked the vet about the shakiness of Topaz's left front leg and the vet said that he's tied at the knee. I've googled, I've searched the forum but I can't find very good info. All the vet said was that if he's lived this long like that it shouldn't be a problem and I should ride him fine.
What does this mean for riding?
How does it affect a 19-20 year old horse?
Is there any special care I should be doing to help maximize the muscles and strengthen his legs?
Anything else I should know about this condition?
