Arthroscopy of the ankle: technique and normal anatomy.

The authors present a modified technique of ankle arthroscopy and describe the intra-articular anatomy of the ankle joint as it relates to the establishment of arthroscopic portals. Cadaveric dissection was used to demonstrate the relationship of the tendons and neurovascular structures to the placement of the arthroscope. Diagnostic arthroscopy of the ankle can be systematic and reproducible when the surgeon is knowledgeable of the intra-articular and extra-articular anatomy of the ankle and when attention is given to accurate placement of the arthroscopic portals and to consistent surgical technique.
