Hey! I had a THR just 2 days ago and am 1 week shy of my 42nd bday. It was a long hard decision. I’m also a PT. I would say sooner rather than later. I kept justifying putting it off because I could still work, walk, and do my Peloton. I was occasionally run/walking but it wasn’t great. I also could no longer row or do pretty much any lower body lifting. At some point, you have to look at what you’re giving up not what you can still do. I’m not sure if anyone follows Kelly Starret on IG but he is a PT who owns a CF. He just had a TKR. He really talks about making the decision sooner rather than later. I wouldn’t wait until things are so bad you have no other choice. Your recovery will suffer. My surgeon said my hip looked significantly worse than they had thought.
He was happy I didnt wait any longer. Go for it. Work hard. Put it behind you. Good luck. Hope to be back to running in 6-8 weeks. Grateful for this site.
