Video Summary

Dr. Gus Mazak from the University of Connecticut presents comprehensive insights on acromioclavicular (AC) joint injuries, focusing on acute and chronic cases. Emphasizing the critical role of the acromioclavicular ligament complex in preventing horizontal instability and posterior rotation, he reviews anatomy and biomechanics key to effective treatment. Treatment decisions—operative versus non-operative—depend on individual factors like sport, pain, and severity, with evidence showing comparable outcomes and faster recovery non-operatively. For acute injuries, arthroscopic approaches preserve healing potential, while chronic cases may require open anatomic reconstructions using allografts and cortical button fixation. Surgical techniques highlight careful tunnel placement to avoid fractures and importance of reconstructing the AC capsule to restore stability, especially posterior rotation. Postoperative care includes bracing and protecting the repair for six weeks, with return to sport anticipated around 5-6 months. Ultimately, combining coracoclavicular and AC ligament complex reconstruction offers optimal stability and patient outcomes.
