I had both knees done about 4 years ago. It was the best thing I have ever done for myself. My quality of life is so much better now. I was using a cane for awhile but the most important thing is rehab. You have to work at it but it is worth it. I went for about 4 months. The most amazing thing is after the surgery they get you right up to walk. Good luck to you. I know you will wonder why did'nt I do this sooner.
