2. Fig 1
Arthroscopic release of the lateral half of the right anterior subtalar joint. The patient is in supine position. (A) Anterolateral subtalar portal (ALP) is the viewing portal. Dorsolateral midtarsal portal (DLP) is the working portal. (B) The lateral capsule of the anterior subtalar joint is resected by an arthroscopic shaver via the DLP. (ACF, anterior calcaneal facet; TH, talar head.)

3. Fig 2
Arthroscopic release of the lateral half of the right talonavicular joint. The patient is in supine position. (A) The dorsomedial (DMP) and dorsolateral (DLP) portals are interchangeable as the viewing and working portals. (B) The dorsolateral portal is the viewing portal. The dorsal capsule is stripped from the navicular by an arthroscopic shaver via the dorsomedial portal. (C) The dorsomedial portal is the viewing portal. The lateral capsule of the talonavicular joint is resected by an arthroscopic shaver via the dorsolateral portal. (Nav, navicular; SL, spring ligament; TH, talar head.)

4. Fig 3
Arthroscopic view after complete release of the lateral half of the right talocalcaneonavicular joint. The patient is in supine position. This is a composite picture. The lateral part of the talar head and talonavicular joint is viewed through the dorsolateral midtarsal portal and the plantar part of the talar head and anterior subtalar joint is viewed through the anterolateral subtalar portal. (ACF, anterior calcaneal facet; Nav, navicular; SL, spring ligament; TH, talar head.)
