Hey I had both knees done on November 8th of '07---Do not think, "Can I do this...what if I fail?" JUST DO IT!!! YOU WILL BE SURPRISED AT WHAT YOU NEVER KNEW THAT YOU COULD DO.
It will be hard work; it will have its ups and its downs, but you will do it---you do not have a choice and you want your life to get better---never, ever, question your abilities---you do not truly know what you are capable of doing after the surgery and throughout the therapy.
