apanteli; I don't have this problem and never had a Arthoscopy. But I do work in the Operating room as well and performed Arthosocpies. Arthroscopy is a much less invasive procedure than an open surgery. You'll end up with one or two little incisions instead of one large incision. The surgeon will work using a scope and camera and laproscopic instuments. Your pain will also be much less with this type of procedure. I usually recommend a second opinion if a person is told that they need surgery. The problem with this diagnosis is that many physicians have never heard of Femoral Acetabular Impingement. Hope this helps
