Non-inferiority Evaluation of Multicenter, Randomized, Single-blind, Parallel-controlled Clinical Trials on the Safety and Efficacy of Full-suture Anchors for Rotator Cuff Injury and/or Shoulder Instability Surgery

Multicenter, randomized, single-blind, parallel-controlled non-inferiority assessment for safety and efficacy of rotator cuff injury and/or shoulder instability surgery

This clinical trial compares the clinical effects of rotator cuff injury and/or shoulder instability surgery with the full suture anchor made by Hangzhou Ruijian Mastine Medical Equipment Co., Ltd. and the polyether ether ketone bone anchor system made by Arthrex, Inc., USA, and evaluates the safety and effectiveness of the experimental device in clinical application

Inclusion Criteria:

1. The age of the patients ranged from 18 to 75 years (including 18 and 75 years), with no gender limitation
2. Patients with rotator cuff injury and/or instability of the shoulder joint are eligible for surgical indications of suture anchor
3. Subjects were willing and able to sign informed consent

Exclusion Criteria:

1. Patients with severe osteoporosis；
2. A variety of conditions, such as previous infection, suspected infection, current infection, that may or may lead to insufficient implant support or impaired rehabilitation；

4. Patients with abnormal liver and kidney function [SGPT (ALT) or SGOT (AST) or creatinine (CR)] were 1.5 times higher than the upper limit of normal value; patients with coagulation dysfunction (such as prothrombin time (PT) prolonged or shortened > 3 s, activated partial thromboplastin time (aPTT) prolonged or shortened > 10 s, platelet count (PLT) < 50 *109/L)；
5. Those with severe cardiopulmonary disease and uncontrolled epilepsy within half a year are limited to participate in the study；
6. Cervical spinal cord disease, brachial plexus nerve injury, poor compliance, psychosis, mental disorders, difficult to cooperate with；
