The incidence of retear following rotator cuff repair remains a major concern, and the cause and timing of retear remain unclear. The aim of this study was to prospectively investigate the timing of retears following rotator cuff repair at multiple time intervals. The hypothesis was that the 'critical period' for retears extends beyond the first three post-operative months.The authors prospectively studied 206 shoulders that underwent arthroscopic double-row (without suture bridge) suture anchor repair for rotator cuff tears. Patients were recalled to three follow-up visits at the following post-operative time intervals: 3, 6, and 12 months or longer. Ultrasonography was performed at each visit, and Constant score was collected during the last visit.A total of 176 shoulders attended all required follow-up visits with mean age 56.0 years. Ultrasonography revealed retears in 16 shoulders (9.1
