Acromioclavicular (AC) joint instability is a common issue. The stability of this joint depends on the combined support of the coracoclavicular ligaments and the AC ligament and capsular structures. Several surgical methods for treating horizontal instability have been reported. The arthroscopic Weaver-Dunn procedure, involving the transfer of the acromial end of the acromial-coracoid ligament to the clavicle, is a well-known option for coracoacromial reconstruction, particularly for addressing vertical instability. This technique has demonstrated positive functional and clinical outcomes. We modified the Weaver-Dunn procedure to treat horizontal instability of the AC joint. Using this technique, we transferred the coracoid end of the coracoacromial ligament to the clavicle.

Article Synopsis
- - Acromioclavicular (AC) joint injuries are common in sports, and the Modified Weaver Dunn (MWD) technique is a traditional treatment, but tendinous grafts are becoming more popular due to MWD's limitations.
- - A study analysis reviewed four research papers, assessing outcomes like infections, patient scores, and joint stability after surgery. Tendinous grafts resulted in better patient scores (ASES and Constant-Murley) without increasing complications.
- - While tendinous grafts showed improved patient scores compared to MWD, both methods had similar rates of complications and stability, with no significant clinical importance identified in the score differences.

Background: Acromioclavicular joint (AC joint) disruption is a common injury with considerable variation with regards to surgical management. The Lockdown™ procedure (previously known as Surgilig™), Modified Weaver-Dunn procedure, Arthroscopic AC joint stabilization and Ligament Augmentation and Reconstruction system (LARS) procedure have all been described for treatment of this injury with varying outcomes.
Purpose: To measure the functional and radiological outcomes following all cases of AC joint reconstruction using the Lockdown™ technique over the last 10 years at Medway Maritime Hospital.

Background: Treatment of Rockwood type III-V acromioclavicular (AC) joint injuries remains controversial. Numerous reconstruction techniques have been proposed. The purpose of this study was to describe the complication profile in a large cohort of patients who underwent surgical management of AC joint separations using a variety of reconstruction strategies.

Introduction: Surgical treatment is usually recommended for acute, high-grade acromioclavicular joint (ACJ) injuries. A wide variety of surgical techniques exist, and the literature does not strongly support one over the other. In this literature review, we describe and compare the results of different surgical treatments for the management of acute unstable ACJ dislocation and aim to guide surgeons on optimal treatment.
