I had a THR 4 months ago. I did not do any exercises before that time but I'm sure if you do a Google search you will come up with plenty of them. I had a spinal but before that I had an IV with plenty of sedation. I felt absolutely nothing until the nurse woke me up hours after surgery telling me to get up and get out of bed. Before I was allowed to go home I had to climb a set of stairs using crutches. Of course the nurses were there every step of the way. I was absolutely going home and needed to focus to pass the test. I had a complex hip replacement but went home that same night.
