Just shy of 2m tall myself, and I don’t seem to have any of your issues, even nosing into my sixth decade on this rock.
About the only thing I could complain about is the family orchard tractor, which is Chinese-made, and seems to have been designed by someone a full 45cm shorter than I am. But that’s about the only thing I have cause to complain about. Some appropriate warm-up exercises and my knees are fine even after a few hours of vigorous pedal-pumping at inappropriately pretzeled leg angles.
While stretching and certain exercises could have helped greatly with that, it’s also not something that would have been available to us in our youth. It’s only been in the last two decades that kinesiology, stretching, targeted training, and other body-movement sciences have started becoming widely available. And that doesn’t help anywhere near as much after the fact.
My condolences on the current state of your meat vehicle.
