Experienced Arthritics Here?

In my opinion surgery of any type is always a last resort. I had a torn
meniscus and elected to have arthroscopic surgery. The initial surgery apparently went well and the doctor said everything else was fine. nine weeks later after terrible pain for the last six weeks the doctor finds that the lower portion of my femur had died. No explanation except that the blood flow stopped for some reason, possible trauma from the initial surgery. The result was a total knee replacement.
I have since been very skeptical of surgery of any type.
