@debbraw: regarding the 3 major problems your OS mentioned: I think just about everyone can check the kneeling discomfort, unfortunately I can also check the clicking sound (which seems to be permanent, unfortunately). To balance those 2 strikes, my numbness totally went away within about 9 weeks post-surgery. Would have traded longer recovery from numbness for no clicking any day, though. Glad that both your TKR’s and recoveries went well.
