Yes, I know exactly what you are talking about! While I have been able to run pretty well following my THR, it is “different”..
My Replaced side seams longer however when you actually look at the x-ray and lengths and distances from hip to ankle, I am the same. I believe it is how my body had been compensating over the years. so since my hip replacement, now, 3.5 years ago, I feel more pressure on my right side and right hip… The length of the left “pushing onto” my right. I am sure I will need my right hip replaced in the next five years, but that was probably an inevitability, given my lifestyle of activities and genetics.
