I had my right knee replaced on 1/9/08 and flew to California to see our son on 2/16/08 - a wonderful FUN trip. Just make up your mind that the rehab is necessary and work HARD. You will do great - 6 weeks of discomfort for years of NO PAIN is soooo worth the trouble - you'll be sewing in 6 weeks or less - just get up from your machine and walk every 45 minutes. Good luck!
