Comparison of clinical efficacy between reconstruction of the superior acromioclavicular ligament with acellular dermal allografts and clavicular hook plate in acromioclavicular dislocations
Abstract
PURPOSES
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.
METHODS
Twenty-two cases of acute AC joint dislocation between November 2021 to December 2023 were retrospectively reviewed. All patients were divided into 2 groups based on the treatment with SALR (12 cases) or HP (10 cases). Patients were evaluated radiologically and clinically using coracoclavicular distance and ratio, pain visual analogue scale (PVAS), Single Assessment Numerical Evaluation (SANE), and American Shoulder and Elbow Surgeons (ASES) at postoperative 3 months and 1 year. We evaluated whether patient achieve MCID of PVAS at the last visit, based on the minimal clinically important differences (MCIDs) of PVAS.
RESULTS
The SALR group showed a lower rate of reduction loss (8.3 % vs. 40.0 %) and similar clinical outcomes compared to the hook plate group. Initial SANE score was statistically significantly lower in SALR group (SANE: SALR, 45.8 ± 20.7; HP, 68.0 ± 15.5, p = 0.009), but there were no significant differences in final clinical outcomes, including PVAS, ASES, and SANE scores.
CONCLUSION
SALR with acellular dermal allograft demonstrates comparable clinical outcomes to hook plate fixation and may offer a viable alternative, especially in…
