Arthroscopic Anatomic Coracoclavicular Ligament Repair Using a 6-Strand Polyester Suture Tape and Cortical Button Construct.

Abstract

Acromioclavicular separations are common injuries. Low-grade separations are typically managed with nonoperative treatment. However, surgical treatment is recommended for high-grade separations, as well as for chronic low-grade separations that remain symptomatic. Multiple fixation techniques have been described over the past several decades, including Kirschner wires, hook plates, and coracoclavicular screws. More recently, a single-tunnel suture-graft repair and an anatomic reconstruction reproducing both the conoid and trapezoid ligaments have been described. All described techniques have reported complications, including implant migration, need for implant removal, clavicle or coracoid fracture, and loss of reduction. As a result, there is no single optimal method of operative fixation. We describe our technique for an arthroscopically assisted anatomic coracoclavicular repair using a 6-strand suture tape and cortical button construct.
