About

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

Full description

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
