My orthopedic doctor says it's time for a knee replacement. It's gotten to the point where I can't hardly walk or do anything without a lot of pain. The x-rays show that I'm down to bone on bone with no cartilage on the one side.

Have any of you guys had it done? Are you satisfied with the results? I worry about being able to walk around in the boat and things like that after I get it done. Thanks.
