I had a total right hip replacement February of this year. I definitely needed a walker. I had several people tell me THR is "easy peasy". I think it's misleading to advise this to anyone. This was not the case for me. I had a very difficult time. Not only with swelling, but pain and I used ice machine practically 24/7. I've since found others that had similar experience to mine. Also, I had total reverse shoulder replacement 2 years ago, and did not have nearly the pain that I did with my hip. Everyone's recovery is different. I prepared my home to accommodate a standard walker. Also, my hospital provided an information session prior to surgery. They demonstrated how to use tools to help with putting on socks, grabber and how not to bend over 90°. They suggested a higher seat toilet. I was provided with all of these items thru Medicare. I live alone, so, I stayed one week in rehab, 2 weeks home PT followed by out -pt PT . Pain management was Oxcycodone. Graduated from walker to cane at 6 weeks, walked without cane at 10 weeks. Currently walking without aide. The only remaining difficulty is standing up from a sitting position and getting out of my car. I did purchase a basket for front of walker which I found very useful to carry items. Best of luck on your surgery!
