Objectives: To show the efficiency and safety of a surgical treatment in both acute and chronic acromio-clavicular junction (ACJ) dislocations. Design: Retrospective. Setting: Department of Orthopedics and Traumatology at IRCCS San Raffaele Hospital. Patients/participants: This study was performed on 37 subjects classified as Rockwood grade III–V or Tossy III ACJ dislocation. Procedure: The surgical treatment was carried out by placing a vascular graft (GorePropaten®) between the tip of the coracoid process and the mid-lateral side of the clavicle with two temporary percutaneous K-wires positioned in a parallel manner in the AC ligament through the acromion and clavicle for 30 days to improve stability. Main outcome measurements: Outcomes were assessed using the Constant Shoulder (CS) score, DASH score, subjective satisfaction, and stability of AC joint at 24 months. UCLA scores taken preoperatively and at 15-month follow-up were used to perform statistical analysis significance using a control group treated conservatively. Postoperative X-rays were examined to assess joint stability after 24 months. Results: Preoperative CS score was 51 ± 12 in the acute group and 55 ± 15 in the chronic group. Follow-up mean CS score was 88 ± 11 in the acute group and 82 ± 20 in the chronic group at 24 months. Preoperative DASH score was 19 ± 3 in the acute group and 14 ± 5 in the chronic group. Mean DASH score was 3.60 ± 7 in the acute group and 6.42 ± 6 in the chronic group. Preoperative UCLA scores were 14.6 ± 2 and 15 ± 7 in the acute group and chronic group, respectively. At 15-month follow-up, UCLA scores of 28.1 ± 1.9 and 27.7 ± 1 in the acute and chronic group, respectively, showed a significant improvement (p
