Inspection of a left ankle. The schematic drawing shows the approximate location of the corresponding needle arthroscopic images. Each needle arthroscopic image is accompanied by a photo of the needle arthroscope from a top-down surgeon’s perspective, at the exact moment of inspection. The anteromedial portal is used for inspection of the deltoid ligament and medial gutter (a). The anterolateral portal is used for inspection of the medial talus and tibia (b), central and posterior talus and tibia (c), talofibular articulation (d), and the lateral gutter (e).
