I am a 64 yo male who had left THR in 2018 and will have right THR next week. Bi-lateral dysplasia. I would think that numerous people on this forum have it, as my sense is that it’s one of the leading causes of OA among younger or relatively younger patients. My dysplasia was severe enough to wear out my hips prematurely, but mild enough to make THR straight-forward without any complications. It’s not to say that it never complicates THR, but I think in many cases it does not.
