Injuries of the distal tibiofibular syndesmosis are commonly overlooked or mismanaged, and chronic instability is a debilitating condition leading to premature joint degeneration. Several methods of treatment have been described, mainly screw fixation, arthrodesis, or ligament reconstruction. Most clinical evidence is limited to case series, mainly screw fixation, and there is a general paucity of evidence regarding ligament reconstruction, which is considered to be more anatomic and to restore joint biomechanics. Most papers describe open techniques. We describe an original technique for all‐inside anatomic arthroscopic graft reconstruction of the anterior‐inferior tibiofibular ligament, which is simpler than other previously described reconstruction procedures. In addition to being performed through standard ankle arthroscopy portals, we believe this technique avoids potential complications. Technique Video: video See video under supplementary data.
