Hey Horse Doc,
I have been an extreme horseback rider and trainer my entire life. I was recommended by a Dr that did THR to get a HR because of my age and active lifestyle. I received a Wright C+ (my surgeon discussed the chioce with me, I am a petite female and he said the size of the C+ fit me better) 4 and 1/2 years ago in my right hip. I had osteoarthritis and "bone spurs" galore. Drs were not sure if it was due to riding injury or not ( I was a thoroughbred/QH jockey for about 5 years in the late 80's, early 90's- could have been wear and tear?).
To make a long story short, best decision I ever made!! I can ride better than ever! No pain (or at least, very little! I have aches everywhere!lol!) I still break colts,train cutting horse, show reiners, take long trail rides, etc!
A lot of my anecdotes on the HR recovery and riding can be seen here under Horseback riding (sports).
Good luck! Hope this helps!
