Background: Acromioclavicular (AC) joint separation is a common injury. The anatomic coracoclavicular ligament reconstruction (ACCR) technique is a viable treatment option, designed to restore the native joint anatomy. Purpose: To evaluate the clinical and radiographic outcomes of patients undergoing ACCR for the treatment of type III and V AC joint injuries with a minimum 2-year follow-up. Study Design: Case series; Level of evidence, 4. Methods: A retrospective chart review was performed on prospectively collected data. Patients who underwent ACCR for type III or V AC joint injuries between January 2003 and December 2015 were analyzed. Clinical outcome measures included the American Shoulder and Elbow Surgeons (ASES) score, Rowe score, Simple Shoulder Test (SST), and Constant-Murley (CM) score. To determine the clinical relevance of the ASES score, the minimal clinically important difference (MCID), substantial clinical benefit (SCB), and patient acceptable symptomatic state (PASS) were used. The pre- and postoperative coracoclavicular distance (CCD) and side-to-side difference in the CCD were measured for radiographic analysis. Results: A total of 43 patients (22 acute, 21 chronic) were included in the study. The mean patient age was 43.4 ± 11.4 years, with a mean follow-up of 3.4 years (range, 2.0-7.5 years). With regard to the ASES score, 92% of patients achieved the MCID, 81% achieved the SCB, and 49% reached or exceeded the PASS. There was no significant difference when stratifying by type (III vs V) or chronicity (acute vs chronic) of injury (both P > .05). The Rowe score improved from 66.6 ± 15.9 preoperatively to 88.6 ± 12.3 postoperatively, the CM score from 61.6 ± 18.8 to 87.4 ± 15.1, and the SST score from 6.2 ± 3.6 to 9.4 ± 3.7 (all P < .001). The postoperative side-to-side difference in the CCD was 3.1 ± 2.7 mm, with type III injuries (2.4 ± 1.9 mm) showing significantly lower measurements compared with type V (4.2 ± 3.4 mm) ( P = .02). No significant trend was found between joint reduction and the improvement in clinical outcomes ( P > .05). Conclusion: Patients undergoing ACCR for acute and chronic type III and V AC joint injuries maintained significant improvement in clinical and radiographic outcomes at a minimum 2-year follow-up. Additionally, 81% of patients reached the SCB after surgical reconstruction.

Background: Revision surgery in cases of previously failed primary acromioclavicular (AC) joint stabilization remains challenging mainly because of anatomic alterations or technical difficulties. However, anatomic coracoclavicular ligament reconstruction (ACCR) has been shown to achieve encouraging biomechanical, clinical, and radiographic short-term to midterm results. Purpose: To evaluate the clinical and radiographic long-term outcomes of patients undergoing revision ACCR after failed operative treatment for type III through V AC joint injuries with a minimum 10-year follow-up. Study Design: Case series; Level of evidence, 4. Methods: A retrospective chart review was performed on prospectively collected data within an institutional shoulder registry. Patients who underwent revision ACCR for type III through V AC joint injuries between January 2003 and December 2009 were analyzed. Clinical outcome measures included the American Shoulder and Elbow Surgeons (ASES) score, Simple Shoulder Test (SST), and Single Assessment Numeric Evaluation (SANE). The coracoclavicular distance (CCD) was measured for radiographic analysis immediately postoperatively and at last postoperative follow-up. Results: A total of 8 patients with a mean age at the time of surgery of 44.6 ± 10.6 years and a mean follow-up of 135.0 ± 17.4 months (range, 120-167 months) were eligible for inclusion in the study. The time from initial AC joint stabilization until revision surgery was 10.2 ± 12.4 months (range, 0.5-36 months); 62.5% of the patients had undergone more than 2 previous AC joint surgical procedures. The ASES score improved from 43.9 ± 22.4 preoperatively to 80.6 ± 28.8 postoperatively ( P = .012), the SST score improved from 4.4 ± 3.6 preoperatively to 11.0 ± 2.2 postoperatively ( P = .017), and the SANE score improved from 31.4 ± 27.3 preoperatively to 86.9 ± 24.1 postoperatively ( P = .018) at final follow-up. There was no significant difference in the CCD ( P = .08) between the first (7.6 ± 3.0 mm) and final (10.6 ± 2.8 mm) radiographic follow-up (mean, 50.5 ± 32.7 months [range, 18-98 months]). Conclusion: Patients undergoing revision ACCR after failed operative treatment for type III through V AC joint injuries maintained significant improvement in clinical outcomes at a minimum 10-year follow-up.

Background: The postoperative failure rate of acromioclavicular (AC) joint fixation using the coracoclavicular (CC) stabilization technique is high. Studies have reported that compared with normal intraoperative anatomic reduction, intraoperative overreduction of the AC joint is more successful in achieving a satisfactory anatomic radiographic outcome at 1- to 2-year follow-up. Purpose: To evaluate the functional and radiographic outcomes and complications in patients with acute AC joint injury who underwent combined CC stabilization and AC capsular repair in which the CC distance was intraoperatively decreased to 50% of the unaffected side. Study Design: Case series; Level of evidence, 4. Methods: In this retrospective study, we collected and analyzed the data of patients with an acute AC joint injury (Rockwood type 5) who underwent combined CC stabilization and AC capsular repair during which the CC distance was decreased 50% compared with the unaffected side. At 2-year follow-up, we evaluated functional outcomes (American Shoulder and Elbow Surgeons [ASES] score), radiographic outcomes (alignment of the AC joint in the vertical and horizontal planes, tunnel widening), and complications (infection, clavicular fracture). Results: The study included 20 patients with a mean ± SD age of 42.20 ± 10.10 years. The mean follow-up period was 33.75 ± 11.50 months. At the 2-year follow-up, the mean ASES score was 95.13 ± 5.61. The overreduction alignment, anatomic alignment, and loss reduction alignment rates were 0% (0/20 patients), 95% (19/20 patients), and 5% (1/ 20 patients), respectively. No statistically significant difference was found in the mean CC distance between the affected and unaffected sides on radiographic evaluation. The mean medial clavicular tunnel width and lateral clavicular tunnel width were 5.03 ± 0.68 mm and 4.47 ± 0.67 mm, respectively. None of the patients experienced fractures or infections. Conclusion: Excellent functional and radiographic outcomes and no complications were seen at 2-year follow-up in patients with acute AC joint injury who underwent combined CC stabilization and AC capsular repair with the CC distance intraoperatively decreased to 50% of the unaffected side.
