120 patients scheduled for arthroscopy due to rotator cuff tear and concomitant superior labrum-biceps complex lesion, were randomized to one of three arthroscopic management options for the LBLC lesion: simple debridement of degenerative tissue, tenotomy of the long head of the biceps tendon, or tenodesis of the long head of the biceps tendon. The purpose of this study was to compare patient-reported outcome measures (PROMs), shoulder range of motion (ROM), and complications between groups over 1 year follow-up. No significant differences in PROMs or shoulder ROM were observed between the three groups. Tenodesis and debridement groups demonstrated better recovery of shoulder supination strength compared to tenotomy. Observed "Popeye" deformity was significantly greater in the tenodesis and tenotomy groups compared to the debridement group.
