Hi, I am new to this site.
I have had the medial patella ligament splitting operation AND then, severing operation done on my Standardbred mare.
The splitting operation made them much worse – she caught on every stride after it. The severing one was a complete success and she could even still sleep standing up, which amazed me, but my Vet said that it is not uncommon, contrary to the information found on the internet.
You can see her story here – Medial Patella Ligament Desmotomy.
