Arthroscopically assisted anatomical coracoclavicular ligament reconstruction using tendon graft.

We describe a method of arthroscopically assisted, mini-open, anatomical reconstruction of the coracoclavicular ligament. This method restores both components of the native ligament with the aim of achieving maximum stability with minimal disruption of the normal anatomy. Using the same principles of ligament reconstruction that are employed in other joints, transosseous tunnels are created following the native footprints of the conoid and trapezoid ligaments and an autologous graft is fixed using a PEEK screw. Adequate healing of the ligament occurs within the bone, to prevent stress risers with an appropriate working length. This procedure is unique, as it replaces the torn ligament with a natural substitute, in the appropriate location, through a minimally invasive procedure. This technique would be suitable for treatment of patients with either grade III or V acute acromioclavicular dislocations. Clinical outcomes for the first 13 consecutive patients treated with this procedure are reported, revealing excellent satisfaction rates with a Constant score of 96.6 at final follow-up.
