Clinical Effect of PRP with DPASB on Full-Thickness Rotator Cuff Tears and Its Role in VAS, SST, and Constant Scores of Patients by Yingbo Wu, Rong Wang, Qingcai Meng

Background: The aim of the study is to probe the effects of platelet-rich plasma (PRP) plus double-row anchor suture bridge (DRASB) under shoulder arthroscopy on the postoperative VAS, SST and Constant scores, rotator cuff tendonbone healing, and re-tear of patients with full-thickness rotator cuff tear (RCT).
Methods: A total of 60 patients with full-thickness RCT treated in our institution from August 2019 to January 2020 were picked and assigned to either group A (n = 30) or group B (n = 30) on a voluntary basis. Group B received DRASB under shoulder arthroscopy, whereas group A underwent DRASB under shoulder arthroscopy plus PRP. We compared the curative effects of both groups.
Results: Week 2, 4, 8, 12 after surgery and 6 months after surgery, VAS scores of patients in both groups declined saliently, whereas SST and Constant scores elevated, and the decrease/increase amplitude of patients in group A was sharply higher than that in group B (p < 0.05). At T2 and T3, abduction 90° external rotation, abduction 90° internal rotation, abduction and anteflexion in both groups increased strikingly, and group A harbored a brilliantly higher increase than group B (p < 0.05). At T2 and T3, serum NO and IL-6 contents were prominently dwindled in both groups, and group A held a plainly higher decrease than group B (p < 0.05). At T3, in comparison to group B, the rotator cuff tendonbone healing rate and quality of life scores in group A were higher (p < 0.05), whereas retear rate was dramatically lower (p < 0.05).
Conclusions: DRASB under shoulder arthroscopy plus PRP therapy can blatantly meliorate the curative effect of patients with full-thickness tear, improve the shoulder joint function and tendonbone healing rate, reduce the postoperative pain degree and the incidence of retear, and can be more broadly promoted and applied clinically.
