    Abstract

    Purpose

    To evaluate the clinical and radiologic results of the arthroscopic treatment using TightRope® (Arthrex, Inc, Naples, FL) for management of acute acromioclavicular dislocation.

    Materials and Methods

    Twelve patients with acromioclavicular joint dislocation Rockwood type V are underwent the arthroscopic acromioclavicular joint reconstruction using TightRope® between March, 2008 and March, 2009. The average age was 40.4 years (range 25~63 years) and mean follow-up was 10 months (range 8~16 months). The shoulders were evaluated using parameters include radiologic measurements by comparing the clavicle posteroanterior and lateral radiographs with the contralateral one. Clinical evaluation was made for pain, function, and range of joint motion by Constant score and KSS (Korean Shoulder Score).

    Results

    All twelve patients returned to their work without pain in 3 months after operation. The average Constant score and KSS score was 98.4 (range 97~100) and 97.8 (range 97~100) at the last follow-up. Because of technical error and indication error, two patients showed failures of TightRope® fixation on the coracoid side and the acromioclavicular joint was redislocated, so these cases were excluded. 10 patients were satisfied with functional results and cosmetic appearance.

    Conclusion

    Considering its less morbidity, less hospitalization, excellent cosmesis, early rehabilitation, this new technique offers an attractive alternative in acromioclavicular joint stabilization if the early technical error would be overcome.
