I was fortunate - they were able to do a partial replacement. I was in the hospital only overnight and then stayed with someone until this afternoon. I can't believe that four days ago they had my leg wide open and I'm walking, sometimes without a cane! The CPM says I'm at 90 degrees and my instructions were to not set it past that until after my staples are out. The staples freaked me out the first time I saw them. I look like a piece of drywall held together with a staple gun! I was terrified and I will admit the first night was not pleasant, but it gets a little better every day. I am diligently doing my exercises and looking forward to a life without pain! Have faith, all - even us chickens survive!
