Controversy exists regarding the optimal technique for arthroscopic rotator cuff repair. The purpose of this multicentre randomized double-blind controlled study was to compare the functional outcomes and healing rates of double-row suture techniques with single row repair. Patients undergoing arthroscopic rotator cuff repair were randomized to receive either a double row (DR) or single row (SR) repair. The primary objective was to compare the WORC score at 24 months. Secondary objectives included anatomical outcomes by MRI or ultrasound, the Constant, and ASES scores. A sample size calculation determined that 84 patients provided 80% power with a 50% effect size to detect a statistical difference between groups.Purpose

Controversy exists regarding the optimal technique of subscapularis mobilization during shoulder arthroplasty. The purpose of this multicentre randomized double-blind study was to compare the functional outcomes and healing rates of the lesser tuberosity osteotomy (LTO) to the subscapularis tenotomy (ST). Patients undergoing shoulder arthroplasty were randomized to receive either a LTO or ST. The primary outcome was to compare subscapularis strength, as measured by an electronic hand-held dynamometer at 12 months. Secondary outcomes included range of motion, WOOS, Constant and ASES scores. A sample size calculation determined that 80 patients provided 80% power with a 50% effect size to detect a significant difference between groups.Purpose
