I have a dual mobility implant. As the name implies, it’s for increased range of motion, not for running. In my case, I’m a double jointed person who likes to sit twisted up like a pretzel and do yoga. My range of motion is the same as before surgery, except that I’m careful not to put my legs in what my surgeon calls “the W position” and I haven’t tried to do a split. The risk of dislocation with this implant is very low, once fully healed. I do run with it, but I don’t do heavy mileage – I never did.
