I was playing dance central on xbox kinect two years ago and dislocated my knee. My nana came in and said dont be a drama queen Jess and I pointed to my knee, my knee cap was on the side of my knee. I was taken out on a stretcher t all the neighbours coming out of their houses to see why there was an ambulance with flashing lights, asked if I wanted morphine but refused and got through it on can after can of gas and air before getting it put back into place. Got told if it happens again I'll need an op on my knee and at physio they pointed out its not fully in place so heres hoping I don't have to repeat that awful experience again...
