Knee brace at Hanger

My surgeon sent me to a place called "Hanger", near the Save Mart, to get my knee brace. The receiption signed me up for an appointment on 4/8 - 10 days from now. You can't make this stuff up. I went along with it, because after he the mistreatment at Reich's I do not see other options. If I knew how to take a measurement correctly, and what to expect after the surgery, I would order this on Internet somewhere, but I don't.
