Thank you for your comment on my page and good luck to you with your knee replacement surgery. It was absolutely the best decision I could have made and I'm so happy I had it done. I have my life back again and I'm sure you will too. It's good that you are trying to take off a bit of weight prior to the surgery. I did that as well and it did make a difference. Be sure you work hard on your physio after the surgery and you will do great. Stay in touch and let me know how you make out, I'd love to hear from you.
