Is a knee replacement a disability?

You can go to the tag agency and fill out some forms, in return they can give you a TEMERARY disablity parking tag. A knee replacement would be somthing that would "disable" your range of movement, but because it is not permanent, you would not be accepted by society or by societies standards as a disabled person. However, you can manipulate society into accepting you as a a person with a disability if you take on the "disability" role. There is no way to explain what this role invovles, because it is different for each person, but you can use it if society accepts it.
