What the trial is, and whether it could suit you
Rotator cuff tears result in shoulder joint pain and movement disorders, affecting patients' daily lives. The incidence rate rises with age and can be as high as 54% among people over 60 years old. Most rotator cuff tears are unable to heal spontaneously, and the tear area may gradually expand over time. Currently, the main surgical treatment for rotator cuff tears is to use suture anchors to stitch the rotator cuff tendon tissue back to the original anatomical insertion point. Large rotator cuff tears are often accompanied by fat infiltration and tendon retraction. When forcefully sutured, the tension is relatively high, which may lead to non-healing and re-tearing of the rotator cuff. Research indicates that the re-tear rate after rotator cuff tear repair is 20% - 30%, and this probability can reach 40% - 50% for large rotator cuff tears. For these irreparable and large tears, rotator
