Comparison of clinical efficacy between reconstruction of the superior acromioclavicular ligament with acellular dermal allografts and clavicular hook plate in acromioclavicular dislocations

We aimed to compare the clinical efficacy of superior acromioclavicular ligament reconstruction (SALR) using acellular dermal allograft with that of clavicular hook plate fixation (HP) in patients with acromioclavicular (AC) dislocations. We hypothesized that the SALR could provide more stability than hook plate.
