Dr. O- what is the reasoning behind the estrogen injections for 3-5 weeks? In humans, I think I remember that estrogen relaxes the ligaments, and blood vesels. A preganat mare has more estrogen in her system than a barren one, and her ligamnets and muscles get more relaxed as her estrogen increases. Wouln't this shot produce the opposite effect of "tightening" a ligament?

Chris, My gelding had a riped medial patellar ligament. The ligament was approx. 50% riped, whiched caused his stifle to be loose. When he walked if you look from behind he would kind of rotate the stifle/leg out. This is a sure sign of a problem. Also the vet said if the stifle is loose, when you back the horse up his leg would lock. My gelding never had a problem with his leg locking up. Plenty of turn out in a hilly paddock really helped rehab him. He is back to jumping now! P.S. Enjoy your new horse!!!!!

Hello Natalie,
The rationale is it creates relaxation of a overly tight ligament. Just as it is not clear this is rational therapy it is not clear that the ligament is overly tight (or loose) condition. The pathogenesis is thought to be due to overly straight conformation of the stifle but not all cases seem to fall into this group.
Leslie, since the ligament was not completely severed the change in gait you saw was probably a response to pain but not do to "looseness" in the stifle.
