Word of advice. At 73 you might not want to be too patient. If it starts to affect how active you are, address it. At your age, once mobility is gone it doesn’t like coming back.
The saying I’ve heard from the ortho I work with is, “if they roll in(in a wheelchair or walker), they’ll be rolling forever.”
It’s not just strength that goes, it’s the will, balance, and neuromuscular function.
You sound like awesome! I hope to be as active as you at 73 and beyond. Already a pretty tough road for me going forward though. 30 years old and 2 knee surgeries in, but thankfully I’m in the health field and can manage my own rehabilitation. Keep on rocking!
