PT is essential !!!! If you don't want further complications I would do some. I have total hip replacement for 25 yrs now. Thank you Lord no revisions at all. Walking is best p.t. after healing. Aqua therapy I did for like 2 yrs to get all muscles strong to hold that hip in place. That is the key ! Ligament, tendons, and muscles need to be strong and flexible. I had one of the best surgeons who cared for my well being not just about surgery and lining his pocket with repeat surgeries. Key as I said is keeping it all strong to hold everything in place !!!! Wish you the best on your journey. Lord bless you and keep you !
