This study states that Some comparative studies have reported improved outcomes for early compared with delayed reconstruction for high-grade acromioclavicular (AC) joint dislocations. However, most are based on older techniques and did not specifically involve reconstruction of both the coracoclavicular (CC) and AC joint ligaments. The purpose of this study was to compare functional outcomes of early vs. delayed surgical intervention of AC joint dislocations managed with combined CC and AC ligament reconstruction.

A retrospective comparative study was performed of 53 patients who underwent early (<2 weeks after injury) or delayed (≥2 weeks after injury) open stabilization for AC joint dislocation. All patients were managed with the same surgical technique of combined CC reconstruction and stabilization of the AC joint, except for the addition of a gracilis allograft for biologic CC reconstruction in delayed intervention. Outcome was determined at a minimum follow-up of 12 months, using the Acromioclavicular Joint Instability (ACJI) score, Taft score, Subjective Shoulder Value (SSV), visual analog scale (VAS) for pain, and overall satisfaction.
