Glad I’m not alone with minor knee issues long-term. However, I’m happy to report that I at least have no morning or other stiffness, and the only time I really notice trouble with low seating is when having to use the X-low commodes common in airports and other public places. Still, I definitely am aware of the TKR knee, just in different ways. Now I’ll leave you alone for a while and be content to hear about and applaud your ongoing rehabilitation.
