Dear avj123: lunula raised some good questions. They were the same I asked myself after years of "dealing with" knees. My husband and I used to ride observed trials motorcycles in national competition. In 1976 I tore my meniscus in the left knee. I was 26. Recovery was rugged but I made it through. In 2009 I tore meniscus in the right knee and my doctor went in to deal with that. I also had Synvisc in both knees which did not help. I am now 64 almost 65. Dealing with my knees has been a long road. I think we all share the same questions, concerns, and doubts, as lunula said. I think it is important to have a doctor who does many knee replacements a year and has a great team to work with. My doctor did my knee and four others on the day of my surgery. He does hundreds of these a year and knows my knees very well. For me, the issue was my current quality of life. In 2012 I walked a half marathon using 2 canes. I used 2 canes whenever I wanted to walk more than a mile. In June of this year I fell down my basement stairs and really did a number on the right knee. My quality of life tumbled and I determined it was time for a change. I am almost 4 weeks post op and so glad I did this. My quality of life is improving everyday. Only you can make the decision but we hope you will stay with us and share how things are going. This is a great place to learn and to share concerns.
