Did not mean to scare you about getting good out of the car. It should not be a problem if you do it slowly. What I meant about weight bearing slowly is wheen descending steps. I came down too hard, my knee flexed to the 30 degrees causing quads to contract and it popped the repair again. just come down slowly you should be fine, Just take it nice and slow.
One more thing about the airport, if you have a difficult time walking longer distances you can call the airline and arrange for a wheelchair between gates especially if you are making connections. I did it flying down to fla. But I felt weird being hauled around and the rest of the times, that's just me.
