DEAR DOCTOR K: I'm a lifelong runner with severe knee pain. I hate the thought of surgery, but hear it's not such a big deal these days, using arthroscopy. How do I know if I'm a good candidate for it?
DEAR READER: Arthroscopy is a technique used to diagnose problems in the knees and other joints. If a problem requiring surgery is identified, arthroscopic surgery can be performed. To appreciate how valuable arthroscopic surgery is, you have to understand what things were like back in the "old days" -- like when I was in medical school.
