i've had a second arthroscopy (last one was 7 yrs ago on the same knee), camera in the knee, cartilidge trimmed and a lateral release of my knee cap which means they've snipped away at the area at the side of my knee cap to release it a bit. I'm in a bit of a state really, still can't walk without crutches or my knee just gives way but I was only supposed to use them for 2 or 3 days. Physio on Thursday so hopefully they will tell me what to do!
