I've got a torn meniscus on the outside of my right knee which gives me stability problems, and arthritis on the inside of the knee, which causes the pain. There is also arthritis in my other knee, but not as bad.
That sounds more like arthroscopy than it does a total joint replacement. About 15 years ago I slipped on stairs and caused a tear in my meniscus. I got the knee scoped to clean out the debris, about 6 weeks of physical therapy, and all was good. Granted I was in my 30's then, but still it was minimally invasive and the results were great.
Now, if your cartilage is completely gone, you have bone-on-bone contact, and significant arthritis then replacement is probably the solution. If I were you, I'd look into getting it scoped then go through therapy before I really considered joint replacement.
