help help PLEASE

Please HELP
I have been crocheting for years now, and I am Looking for a special pattern for a doctor who has been helping me for the last 15 years of my life. Well let me tell a litter about this, 15 years ago I walk in to the hospital
to get a new knee and long story short I have been in a wheelchair ever since. I was told I would never walk again, and the movement of air or anything touching my right leg would hurt. So being house bound I started crocheting about 8 years ago as away to help with the pain and being home alone. This doctor has over the years work hard finding new treatments
trying to help me, well after Christmas we are going to try the last one and cut off the leg with it. Yes we looking at this as a good thing... But I would
like to repay this doctor with a afghan because of all his hard work he has done for me over the years. But I just can not find a pattern that would say
thank you, and I trust you with my life..
PLEASE if anyone can help.
