Arthroscopic rotator cuff repair has a high rate of successful subjective and functional results. Although the rate of tendon healing is reported to be around 80% for small tears, it can decrease to about 30% for large and massive tears. Poor tissue quality of bone, tendons, and muscles can affect healing and functional recovery of the rotator cuff and has been advocated as a major cause of tendon nonhealing and/or retear. Several biological augmentation procedures have recently been suggested to enhance tendon healing after Arthroscopic rotator cuff repair, such as marrow-stimulating technique with microfractures of the greater tuberosity. The purpose of this study was to introduce a new technique, greenhouse technique, and to compare the clinical outcomes with microfracture combined with suture bridge technique.
