Brief Summary

Abstract Introduction: The high prevalence of sprains in the population has provided a substantial number of patients with lateral instability of the ankle. The continuity of this condition can lead to the progressive loosening of the medial containment structures, generating a multidirectional rotational instability. The deltoid approach through the imbrication of its components has been proposed as a solution for these patients. The arthroscopic technique has been described as an alternative. Methods: This is a retrospective study with patients diagnosed with multidirectional instability and submitted to an ankle arthroscopy with medial repair (arthroscopic tensioning) and lateral (arthroscopic Brostrom) between January 2018 and January 2020. All patients will fill an epidemiological questionnaire and will be evaluated for pain and function according to the Visual Analogue Scale (VAS) and the American Orthopaedic Foot and Ankle Society Score (AOFAS) at 12 months (6-24 months) average of follow-up. Discussion: The combined medial and lateral arthroscopic repair may be an effective and safe alternative in the treatment of multidirectional instability. The inclusion of the deltoid complex and the low invasiveness of this technique can improve the clinical outcomes of these patients. Additional studies, with a prospective and comparative methodology are required to sustain this proposal. Design: Level IV. Retrospective case series.

Multidirectional

Arthroscopic lateral ligament repair combined with deltoid arthroscopic ligament repair.

Procedure: Arthroscopic Brostrom combined with Arthroscopic Deltoid Repair

Interventions

After anesthesia and surgical site preparation, traditional arthroscopic portals were performed. A 4.5mm set was used to clean the joint and assess possible associated injuries. Anterolateral and anteromedial impacts were resected when needed. Lateral and medial instability were confirmed arthroscopically, and ligament repairs prepared, starting by the lateral compartment. A traditional Arthroscopic Brostrom was performed, using one anchor and suture passers. Sutures are passed but not tightened. Medial anchor insertion is executed at the medial malleolus, in the quadrant described by Vega et al. Sutures were passed respecting the safe zone illustrated by Acevedo at al. The ankle was positioned in neutral (no posterior drawer) and the lateral sutures tightened with arthroscopic knots. Finally, the medial repair is finalized by tightening the deltoid sutures with the ankle at the same position. Portals were closed and a dressing applied.
