Prospective Randomized Controled Study on the Outcome of Greenhouse Tec in the Arthroscopic Treatment of Small to Medium Rotator Cuff Tear

According to the anteroposterior diameter of the injury, single or double high braided thread were used to suture the tendon in a modified Mason Allen way without knotting. Bone marrow stimulation was carried out in the footprint area of rotator cuff. A 2.0 mm diameter cone was created with a depth of 1 cm and a spacing of 5 mm. Six to eight holes were made due to the diameter of the tear of rotator cuff until blood and fat droplets exudate. Then the threads were passed through the locking eyelet of the lateral row anchor. After tightening the threads, the anchor was screwed in at the distal part of the gteater tuberosity. With this new technique, the rotator cuff was repaired by one lateral row anchor without medial row knotting.
