My left THR posterior was done Sept 26th. I was walking up a flight of stairs the next day – slow, but no problem. I also had a waterproof dressing and was able to shower within two days. Surgery was at Ascension Providence in Novi, Michigan.
I’m 63 and already able to walk 5’miles. Getting clearance from my ortho next week so I can begin interval training.
Give yourself a gentle week then work on muscle strength. Fantastic team through the CORE institute, an replacement group on several US states.
Good luck!!
