Jeff, I had my hip replaced 13 years ago. My doctor gave me list of several thing to absoultly NOT do. Of course skiing on water or snow was out.
One of the simple tasks he warned me about was a large step up, like stepping up on the tailgate of my El Camino, or climbing on a tractor, or jacked up pickup step. Crossing my legs, or sitting on the floor yoga style, with crossed legs. I have avoided all of those.
After 13 years I still will not use that leg to make the first step up into my El Camino bed. Since I have two legs, it has not been an issue.
My hip replacement is modular, so it can fit people of different size. The plastic insert that is the socket is about all that will wear out. The rest is titanium.
I figure if I get abducted by space aliens, they will know I am from an advanced species, with the titanium hip replacement. Of course with my luck, they will be just harvesting titanium, and remove mine and dispose of me.
