I have this exact experience, 3 years post op on left knee. “Pain and heaviness” is a great descriptor for what I feel in both knees and left hip. So odd that a stiff knee needs a steel brace, but that is the only thing that keeps me from hiking my left hip and wearing it out. I don’t think hip and right knee replacement will be an option, due to so much scar tissue, it buckles and catches my knee replacement when I stand or am lying down. I can manipulate it out of the painful spots but that seems like such an extreme outcome of TKR! I will be following this thread. So helpful to know I am not alone.
