Oh gosh hicktomboy, I am so sorry I stepped into some of that pasture stuff I used to find on my grandparents' farm with my post to Cold Feet B4 Surgery..... I did not realize you are trying to find out whether riding is OK post implant. Reading only there and not in your full range of posts I wrote out of context about riding.
Even so, since I have ridden much and understand your yearning to return to the saddle where you can lean forward and nuzzle your friends, I do SO HOPE your Doc will give you good advice on this concern! Now as for me, well.... just chalk one up for my exquisite ability from time to time to define the word DUH with my goings on.
One who hopes the best for you and your horses,
