                        Several years ago I had arthroscopy on my knee. It relieved the pain for a couple of years. The pain you are experiencing now doesn't sound normal. If you are not receiving satisfactory answers from your surgeon, get a second opinion. Be sure the doctor is a Board Certified Orthopoedist who works only on knees  and hips. For something as important as walking, you want the best.  Good luck.
