Abstract

Ankle arthroscopy is an important diagnostic and therapeutic tool in the treatment of pathologies of the ankle joint. In a series of 7 articles, the basics of ankle arthroscopy are reviewed. In this article (part 4), surface anatomy, portal placement, and diagnostic arthroscopy of the posterior ankle joint are reviewed. We also compare the benefits and limitations associated with performing this procedure with a 1.9-mm 0° endoscope versus a 2.7- or 4.0-mm 30° endoscope.
