I had a partial knee replacement 13+ yrs ago.
There was nothing but crickets when I asked for advice on bike forums at that time.
My suggestion for those putting forth their stories is to state your age.
This is a factor for those reading your stories.
I'm turning 74 at years end.
Cycling is what I love and is the least stressful on the knee, so I've set aside some other activities in favor of what makes me smile more
