Clinical and radiographic outcome after acromioclavicular reconstruction: a single-center comparison of three different techniques.

This prospective, observational cohort study compares the clinical and radiographic outcomes of the modified Weaver and Dunn (WD) technique with the newer, anatomical double-button plus tendon allograft technique (DB), and the suture anchor repair plus tendon allograft (SA). The study cohort includes 53 patients, who underwent surgery for acromioclavicular joint (ACJ) dislocation Rockwood type 3, 4 and 5. Patient-reported outcome scores and clinical results, including Disabilities of the Arm, Shoulder and Hand (DASH), the Subjective Shoulder Value (SSV), the Visual Analogue Scale (VAS) and the Constant score (CS) results as well as loss of reduction rates on plain radiographs were compared.
