Hi I joined the group because I am also facing a TKR spacer replacement surgery. I am 1 year out from the TKR and have stability issues walking. I can walk fine but the muscles fatigue after time. The knee has felt unsteady or wobbly since I could really walk on it. The doctor said this would be a spacer replacement only - nothing more. It sounds like that surgery is not too bad, but I am really worried about infection. Does anyone know if that is more of a potential problem going back into the joint? What about actual surgery time? Were you on a walker and for how long? What about driving? Anyone wonder why the spacer was too small to start with? How do they select the spacer?
