Arthroscopic three-point double-row repair for acute bony Bankart lesions

摘要

After mobilizing anteroinferior osseous Bankart lesion from the glenoid neck, a suture anchor loaded with differently colored non-absorbable braided sutures is placed on the medial edge in the glenoid neck along the rim fracture through the anterior-inferior trans-subscapularis tendon portal. Two same-colored suture limbs on the anchor are then pulled through the labrum using PDS suture shuttling simultaneously. These steps are repeated for the others suture limbs. The two same-color suture limbs located inferiorly are retrieved using the trans-subscapularis tendon portal. Both suture strands are threaded through the eyelet of a PushLock anchor on the distal end of the driver. The anchor is advanced into the pilot hole completely. These steps are repeated for a second anchor at the upper edge of the fracture in the glenoid rim using the anterior portal. This technique confers effective, firm fixation of the bony Bankart lesion by three-point fixation without the suture material crossing the glenoid cavity.
