Yes I had a lot of hesatation regarding the removal of the hardware. I played the what if game. What made it worse is that I am a registered nurse. I got a second opinion and spoke at length with my PT about the next step. My anxiety got so bad I started having BP issues though I had read many medical articles about this I wanted it and knew in my heart it was the next step to healing and getting the TKR. I know not everyone needs their knee replaced but for me I have no choice but to re place it. I want my life back and my mobility!!!
