Not sure if this is helpful, but after I had my left hip replaced (which didn’t go to plan) I was very twisted and couldn’t put my heel to the ground. The NHS aftercare physio thought I’d be like that permanently. Private physio helped me to rebuild muscle strength and to walk with normal foot placement (heel to the ground first), but two years later I was still twisted through my pelvis, which was particularly noticeable when riding (it felt horrible). A friend then recommended a really good Alexander technique teacher.. she has made a huge difference to how I walk (so much so that the physio now refers clients to her). So in future, I would go to a physio for strength/stretching, and an Alexander practitioner for the best combo. I would also consult more that one professional if what they suggest isn’t working for you. Good luck with your recovery!
