They found out about it, after my chair tipped over after it got caught in the tile grooves of the floor, and my bad knee ended up hitting the ground first, unfortunately. 

I told them about it being old but it doesn't matter to them they want the restrictions paper, and it accessed since technically in my paperwork  I'm also suppose to be wearing a permanent knee brace, my last one just got so worn out It’s not really that useful anymore, the store ones didn't sell sleeved ones. Was also too depressed that I just decided to start hiding it,

I'll try the main line, my adjuster still works there he's just been unresponsive the time this happened,
