I used to ride train and compete horses. When I took my first test I was amazed at their anatomy and physiology and could not get over the fact that their legs are not elongated ankles but elongated middle fingers and toes. They are running on their fingers. Millions of years of evolution yet still incredible.
Their legs work like a spring loaded mechanism supported by a pulley system of tendons and ligaments. That advantage is their biggest flaw; no supporting muscle structure means that their legs can shatter rather than break and because they weigh close to a ton as adults, three legs cannot support that weight nor can they run.
The advantage that a lot of money in the race horse industry brought is research into prosthetics, braces and other devices to help young foals. Contracted tendons are not uncommon in Foals and with a lot of care and great stables and people they get a normal life.
If a foal is born that way and the owner has funds compassion and round the clock care; feeding or lifting the foal every two hours. Paying for custom made prosthetics and hoof supports that need to change frequently as the little one grows until the tendons have stretched.
The outcome is a horse with a life that it evolved and was bred to have. This is not AI or AI enhanced but the same foal. Reddit thread also has an explanation of the condition. It's no longer life-threatening, but depends on how much effort the owner will invest.

Incredible what compassion can achieve and what a beautiful gait it turned out to have.
