P004 - Effectiveness of arthroscopic rotator cuff repair with allogenous dermal augmentation in irreparable massive rotator cuff tear
Abstract
Purpose
Surgical treatment of massive rotator cuff tear is variable. The purpose of this study is to compare the clinical and radiological results of arthroscopic partial repair and arthroscopic bridging with an allogenous dermal matrix augmentation in patients with massive rotator cuff tear.
Methods and Materials
We retrospectively reviewed 38 patients with massive rotator cuff tear. Group A included 19 patients with arthroscopic partial repair. Group B included 19 patients with arthroscopic bridging with an allogenous dermal matrix augmentation. Clinical outcomes were evaluated based on the VAS(Visual analog scale), UCLA(University of California–Los Angeles) scores and Constant score. Radiologic evaluation to assess was performed using X-ray, ultrasonography or magnetic resonance imaging.
Results
Mean AHD(Acromial-humerus distance) and functional outcome scores improved significantly in group B(AHD: 10.0mm to 13.5mm, p < 0.001, VAS: 7.3 to 2.3, p = 0.003; UCLA score: 18.8 to 29.1, p = 0.002; Constant score: 63.0 to 86.1, p < 0.001), whereas mean AHD and VAS showed significant improvement in group A(AHD: 9.9mm to 13.0mm, p = 0.002, VAS: 7.2 to 1.4, p < 0.001) and other functional scores increased without statistical significance in the group. No notable postoperative complications been developed in both groups.
Conclusion
Using arthroscopic treatment with allogenous dermal matrix augmentation can be a useful method in terms of clinical and functional outcomes and be considered as a viable alternative to conventional partial repair.
