69 patients with repairable rotator cuff tears and concomitant degeneration of the long head of the biceps tendon (LHBT) were randomized to receive a rotator cuff repair with either an open sub-pectoral (SP) tenodesis or an arthroscopic intra-articular (IA) tenodesis of the LHBT. The primary outcomes of interest were the Constant Shoulder Score and the Simple Shoulder Test (SST). Secondary outcomes of interest included pain on a Visual Analog Scale (VAS) and patient satisfaction. Follow up was performed at 6 months and 2 years post-operation. Results revealed no significant differences between the two groups in all outcomes, at all time points.
