This study is a prospective randomized controlled study of Combined microfracture procedure promotes tendon healing during double raw repair for full tear rotator cuff. The patients with rotator cuff tear were randomly divided into groups before the operation. The patients were followed up before and 6 weeks, 3 months, 6 months, 12 months after surgery. In different time periods, the quantitative and qualitative indicators including pain, functional score, muscle strength, MRI performance, etc. were compared between groups at the same time period to evaluate the difference in the effect of Crimson duvet procedure with Greenhouse procedure on the treatment of rotator cuff.
