I'm glad that you have a scooter and that it has been helpful. I twisted both of my knees climbing bleachers to support my grandson playing in the band at his first ballgame. I have thought of you a lot last night and today as I ice my "pieces and parts".
Can you do upper body water aerobics and just not use your lower body? I know that you love the water so much. I hope that you heal quickly and that your orthopedist has some answers for you to make you hurt less in the future.
