This study was performed to determine whether pre-operative MRI could provide prognostic information regarding clinical outcome following rotator cuff tendon repair surgery. The study group consisted of 141 patients undergoing surgical repair of a full-thickness rotator cuff tendon tear who completed the Disabilities of Arm, Shoulder and Hand (DASH) and Short Form (SF-12) surveys before and one year after surgery. The pre-operative MRI was reviewed to determine tear size, tear retraction, torn tendon tendinosis, and composite muscle atrophy. There was a significant inverse association (p<0.05) between post-operative DASH and SF-12 scores and tear width, tendon retraction, and torn tendon tendinosis.
