Arthroscopic Plication of the Anterior Portion of the Annular Ligament for Lateral Elbow Instability.

The elongation of the annular ligament is a rare injury causing disability and instability of the elbow. The loosening of the annular ligament is also a pathological sign of symptomatic minor instability of the lateral elbow and could be evaluated through the loose collar sign. This Technical Note aims to describe a safe and reproducible all-arthroscopic procedure to plicate the annular ligament with suture anchor through posterolateral and midlateral portals.
