I'll try to give you a long term perspective. For reasons I don't need to address, I have had 2 total hip replacements and 3 revisions, over a period of 6 years. The last was in 2012, and I am doing fine, active and the only pain is from arthritis and a little bursitis.
In 2006 I had both total hips, 3 months apart. My original doc did both anterior and posterior, but would only consider posterior because the hips appeared to be badly eroded on xray and were pretty well frozen in the joints (I was only 55 and of very average weight - he said he expected someone over 85 based on the pics)
Healing time was about 2-3 weeks longer than for my cousin who had surgery at the same time. I was walking with crutches the day of surgery, and with barely a cane after 3-4 weeks, and dancing at 6 weeks.
At 5 years both implants failed and required revision, which the second surgeon did 6 weeks apart, posterior. He would not consider anterior (which he also does) because he said my small stature left "no room for even minor inaccuracy" which according to him is the biggest down side of the anterior approach where the doctor cannot see the joint as well. Those revisions, and a subsequent one were all done within an 8 week period -don't ever do that! The recovery time from 3 major surgeries with anesthesia and blood loss in that short time took a year. A relative my age and size talked her doc into an anterior incision at that time, her initial recovery was about a month shorter than mine. However her joint never aligned right and she still walks with a cane and pain.
Fast forward to 2020 - I barely remember the recovery time, but my hips were positioned exactly right, the scars don't look any worse than my friends' and everything works.
Also, at the times of my surgeries, each doc had done well over 1500 hip replacement surgeries, so I had confidence in their skill.
Here is another strong recommendation : Ask for at least a few a physical therapy sessions, especially if you have had a frozen joint or have been limping for a long time. At a minimum you need gait training to get you walking in such a way as to minimize stress on back and knees. Some strength and flexibility work is helpful as well. And do the recommended exercises as instructed. I am sure that was partly responsible for my success.
