|What's that you say? You sense uninformed internet bullshit?|
Long story short, yes. Horse people are crazy. Still, I couldn't argue with results. Estrone shots DO work to help alleviate stifle issues in my horse. But, how?
I dove deep into the internet archives to try to find an answer, but that seemed to only confuse the issue further. Some said they believed the hormone loosened the ligaments in the stifle, because high estrogen levels are common during childbirth-- a period in which ligaments are known to stretch in women. Others said that actually it tightened ligaments, for the same reason. Even more others said that it encouraged the building of muscle. The reasons went on an on... but none of them actually made sense.
So I made the crazy decision to ask my vet, a certified medical professional. Amazingly, he gave me a very simple and plausible reason the hormone works on stifles...
No, really. Stick with me here. It turns out, there is a fat pad beneath the ligaments involved in locking the stifle. When a horse is given Estrone, the fat pads retain water and bloat up.
|Actually, yes. But in my case it's probably more to do with all the salt and beer I just ingested than hormones.|

So there you go. The easy scientific explanation for how and why estrogen works to alleviate stifle pain. Never say my obsessive research down a horrible rabbit hole of misinformation never lead to profitable information. You're welcome.
