2. Fig 1
Arthroscopic capsular release of the left talocalcaneonavicular joint. The illustrated case is a case of left talar neck fracture that was treated with anterior screw fixation. The arrow head points to the previous fracture site. Lateral (A) and dorsoplantar (B) foot radiographs before the arthroscopic release showed that there is no radiographic evidence of posttraumatic arthritis of the ankle, subtalar, or talocalcaneonavicular joint. Coronal (C) and sagittal (D) magnetic resonance imaging showed that there is no osteonecrosis.

3. Fig 2
Arthroscopic capsular release of the left talocalcaneonavicular joint. (A) Talonavicular arthroscopy is performed through the medial (MMP) and dorsomedial midtarsal (DMMP) portals. (B) Talonavicular arthroscopy is performed through the dorsomedial and dorsolateral midtarsal (DLMP) portals.

4. Fig 3
Arthroscopic capsular release of the left talocalcaneonavicular joint. The dorsomedial midtarsal portal is the viewing portal. The fibrous adhesions medial to the dorsomedial midtarsal portal is released with an arthroscopic shaver via the medial portal. (Nav, navicular; TH, talar head.)

5. Fig 4
Arthroscopic capsular release of the left talocalcaneonavicular joint. The dorsomedial midtarsal portal is the viewing portal. The fibrous adhesions lateral to the dorsomedial midtarsal portal is released with an arthroscopic shaver via the dorsolateral portal. (Nav, navicular; TH, talar head.)

6. Fig 5
Arthroscopic capsular release of the left talocalcaneonavicular joint. Medial subtalar arthroscopy is performed through the medial midtarsal portal (MMP) and the medial tarsal canal portal (MTCP). The medial midtarsal portal is located at the medial corner of the talonavicular joint, just above the insertion of the tibialis posterior tendon (TPT). The medial tarsal canal portal is over the medial end of the tarsal canal that is just posterior to the tibialis posterior tendon and just above the level of the sustentaculum tali. (MM, medial malleolus; Nav, navicular.)

7. Fig 6
Arthroscopic capsular release of the left talocalcaneonavicular joint. The medial midtarsal portal is the viewing portal and the fibrous tissue of the medial gutter of the anterior subtalar joint is debrided and the fibrotic medial capsule is stripped from the sustentaculum tali (ST) by an arthroscopic shaver via the medial tarsal canal portal. (TH,talar head.)
