Aimee-
Watched your competition tape of the 2018 Southern Championship. All I can say is WOW!!. Your strength and flexibility are phenomenal and your ROM is nearly supernatural. Truly astonishing and inspiring. Also inspired me to do a quick research of the history of dance traditions and I would venture that American pole dancing is an extension of a centuries old universal tradition that has included Mujra, Belly Dancing, Ghawaze, Hula, CanCan, Nautch and Tanwaif, and venture further that of them all your performance might very well be the most athletic [although that might be a case of cultural bias]. The irony is that I thought I was making progress getting back to being able to tie my shoes standing up. I hope you medalled with that routine, you deserved it. Your worries about wearing out your hip may be an unneeded concern. There are recent posting from people who had the hip/s resurfaced all the way back to 1999 and going strong with no indication of failure. The devices aren't always at fault, often it is a matter of anatomy or loss of muscle support for the device. You don't look like you're in any risk of lost muscle tone.
