Arthroscopic reconstruction of chronic AC joint dislocations by transposition of the coracoacromial ligament augmented by the Tight Rope device: a technical note.

We present a new arthroscopic technique for chronic AC joint dislocations with coracoacromial ligament transposition and augmentation by the Tight Rope device (Arthrex, Naples, USA). First the glenohumeral joint is visualised to repair concomitant lesions, such as SLAP lesions, if needed. Once the rotator interval is opened and the coracoid is identified, the arthroscope is moved to an additional anterolateral portal.
