Happy NEW DECADE to all! I had TKR on left in 2015. Perfect result - hardly any pain; works well. Had TKR on right knee 13 month ago. Hardly any pain, but more difficulty. I do have the "Tight Band" on top of knee (a little to right of center). Tightness has decreased 70% (?) over the year. However, THIS LEG HAS HAD NUMBNESS SINCE THE SURGERY and still does. Numbness around knee and calf has decreased (maybe 50%), but is still very present. I am concerned about circulation (I do have some circulation issues in both legs showing blue/purple veins especially in feet. When I use corrective stockings it improves for a while.) Two things: I can play a racquet sport with no problem. Climbing UPstairs is definitely a problem now - it is an effort and I have to rest at top (and, again, I can play Pickleball for 2 hours.) Going DOWNstairs I have to hold on, go slowly as my "rhythm" / or coordination is off. Possibly NERVE DAMAGE??? Surgeon has nothing to offer.
