A Randomized Clinical Trial Comparing Open to Mini-Open Rotator Cuff Repair for Full-Thickness Rotator Cuff Tears.

A standard vertical incision was made over the anterolateral aspect of the acromion. The deltoid muscle was split and stripped off the anterior aspect of the acromion. The anterior and inferior aspect of the acromion was removed. The coracoacromial ligament was excised. Repair of the tear in the cuff tendon(s) was accomplished by suturing leading edge of the tear into the greater tuberosity of the humerus at or near the original site of insertion of the cuff to bone. Trans-osseous sutures, suture anchors and tendon to tendon suture repair techniques were employed for a secure repair with the arm at the side. The surgeon was allowed to use whatever method(s) to create a secure repair. The deltoid was securely reattached to the acromion with the deltoid fascia repaired down the split.

A standard arthroscopic gleno-humeral arthroscopy was performed followed by an arthroscopic acromioplasty. Three standard arthroscopic portals were used. The lateral portal was centered in line with the cuff tear, and incorporated into the mini-open incision. Initially, a partial bursectomy was performed to improve visualization. The inferior surface of the anterior acromion and the coracoacromial ligament were removed. Following the arthroscopic acromioplasty, a 3-4cm lateral incision was performed in the area of the lateral portal. The deltoid muscle was split longitudinally to expose the tear in the rotator cuff. The tear was repaired in a similar manner to the open repair with tendon to tendon sutures, trans-osseous sutures and with suture anchors.
