Abstract

TECHNIQUE The technique is performed when the docking site gap is ≤ 10 mm. The level of the docking site is located fluoroscopically (Fig. 1). Medial and lateral arthroscopy portals are created (Fig. 2) and the arthroscope is introduced into the docking site. Fibrous tissue is debrided from the bone ends using an ArthroWand® (ArthroCare UK Ltd; Fig. 3). Once the bone ends are visible, they are freshened using an arthroscopic burr. A fluid management system is used to maintain low pressure flow through the docking site. Bone graft or synthetic graft substitute may be applied percutaneously in cores using a trephine.5 Bone transport continues thereafter and union at the docking site is achieved by compression.
