Return to running using Chi Running after THA?

I had a THA back in 2018. I have been a runner for over 30 yrs. My Ortho. has recommended NOT to run because it will degrade the surface of the appliance. I have been researching Chi Running technique, which says it is not a high-impact running technique. I want to start back using Chi Running, slowly, but wanted to know if there is anyone who has a similar experience and what to expect.
