Lateral Ulnar Collateral Ligament Reconstruction Through a Mini-Invasive Approach

Posterolateral rotatory instability is the most common form of elbow instability, secondary to valgus, supination, and axial loading in elbow extension. The lateral ulnar collateral ligament (LUCL) is the primary restraint to posterolateral rotatory instability and multiple techniques of repair and reconstruction of the LUCL have been reported in the literature with variable outcomes. The aim of this technical note is to describe a minimally-invasive technique using a tendon graft to perform a reconstruction of the LUCL using knotless suture anchors in an onlay fashion, without violating both the articular capsule and the common extensor origin.
