Summary
Using arthroscopic treatment with allogenous dermal matrix augmentation can be a useful method in terms of clinical and functional outcomes
Abstract
Introduction
Surgical treatment of massive rotator cuff tear includes marginal resection, partial repair, tendon transfer, and reverse total shoulder arthroplasty. Recently, studies regarding scaffolds, growth hormones, and mesenchymal stem to improve treatment outcomes of rotator cuff are in full swing. Application of allogenous dermal matrix in treatment of rotator cuff tear is becoming increasingly popular for enhancing mechanical strength and biological healing. The purpose of this study is to compare the clinical and radiological results of arthroscopic partial repair and arthroscopic suture bridge repair with Allogenous dermal matrix augmentation in patients with massive rotator cuff tear.
Method
38 patients with massive rotator cuff tear who have undergone arthroscopic surgery were enrolled. Group A included 19 patients with arthroscopic partial repair. Group B included 19 patients with arthroscopic suture bridge repair with allogenous dermal matrix augmentation. Clinical and functional evaluations were performed pre and postoperatively with VAS(Visual analog scale), UCLA(University of California–Los Angeles) scores and Constant score. Follow up X-ray were taken postoperatively for AHD(acromiohumeral distance) analysis. The study was designed on the basis that there was no statistical no statistically significant difference in age, sex ratio, tear size and dominant side between the two groups.
Results
The VAS score improved from 7.2 to 2.5 in group A and from 7.3 to 1.5 in group B. The UCLA score improved from 19.1 to 26.7 in group A and from 17.6 to 29.1 in group B. The Constant score improved from 66.7 to 75.2 in group A and from 56.8 to 71.1 in group B which were statistically significant. Mean AHD(acromiohumeral distance) was increased from 11.6mm to 14.2mm in group A and from 10.0 to 13.7 in group B. There was no postoperative complications in these patients.
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.
