The Subjective Shoulder Value (SSV), the Constant Score (CS), the Taft Score (TS), and a newly developed Acromioclavicular Joint Instability Score (ACJI) were used for final follow-up. Bilateral stress views and bilateral Alexander views were taken to evaluate radiographic signs of recurrent vertical and horizontal AC joint instability.<\/jats:p>\n                  <jats:p>Results: Twenty-eight patients (2 women and 26 men; mean age, 38.8 years [range, 18-66 years]) could be evaluated after a mean follow-up of 26.5 months (range, 20.1-32.8 months). The interval from trauma to surgery averaged 7.3 days (range, 0-18 days). The mean SSV reached 95.1% (range, 85%-100%), the mean CS was 91.5 points (range, 84-100) (contralateral side: mean, 92.6 points), the mean TS was 10.5 points (range, 7-12), and the ACJI averaged 79.9 points (range, 45-100). The final coracoclavicular distance was 13.6 mm (range, 5-27 mm) on the operated versus 9.4 mm (range, 4-15 mm) on the contralateral side ( P &lt; .05). Radiographic signs of posterior instability were noted in 42.9% of cases. Patients with evidence of posterior instability had significantly inferior results in the TS and the ACJI ( P &lt; .05). Neither coracoid fractures nor early (within 6 weeks postoperatively) loss of reduction due to tunnel malpositioning or implant loosening was observed.<\/jats:p>\n                  <jats:p>Conclusion: The combined arthroscopically assisted and image intensifier\u2013controlled double TightRope technique using implants of the first-generation represents a safe technique and yields good to excellent early clinical results despite the presence of partial recurrent vertical and horizontal AC joint instability.<\/jats:p>","DOI":"10.1177\/0363546511399379","type":"journal-article","created":{"date-parts":[[2011,3,25]],"date-time":"2011-03-25T00:46:03Z","timestamp":1301013963000},"page":"1507-1516","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":378,"title":["Arthroscopically
