Hello JC and great question and widely evaluated and debated. The reality is it is new territory and take happiness from the fact we are on the cutting edge.
The technology improvements in our hip prosthetics is fantastic, and the surgeons and physicians knowledge is extensive, but here is what I have come to know… I don’t think anyone really knows…
I believe to take the best you can from many different, trusted medical sources, people that are on this wonderful forum, and then start applying it cautiously to your situation and use how your body feels and experience as a guide.
I read a lot of very conservative and cautious approaches on this list and there is nothing wrong with that… I had a right, anterior, THR approach 10 weeks and two days ago and have gradually built back to running 25 miles per week and covered 14.5 miles yesterday at an average pace of 10:15 per mile elevation gain of about 1600 feet of elevation gain with no pain. Keep experimenting!!
