Currently, rotator cuff healing is defined as "intact", "attenuated", or "failed" based on the observation (or not) of a recurrent defect (i.e., a "gap") in the tendon using MRI or ultrasound imaging. The investigators' previous work has identified a new outcome, in which there is no detectable defect or "gap" in the repaired tendon, but the repaired tendon has undergone significant retraction. The investigators call this outcome "failure with continuity". Current imaging methods are inadequate to determine the extent to which the repaired rotator cuff tendon has "failed with continuity". The investigators have developed an imaging technique to detect this phenomenon. Specifically, radio-opaque markers are sutured onto the repaired tendon. The distance between the tendon markers and the bone is measured from CT scans taken within 2 weeks of surgery, and compared to the distance measured at 3, 6, 12 and 24 months. If the tendon retracts away from the bone during healing, this distance will increase over time. Healing of the tendon will also be monitored in the traditional manner by MRI scans at the same time points. The investigators will investigate the relationship between tendon retraction, MR imaging and clinical outcomes including shoulder strength and patient satisfaction. The investigators expect to show that tendon retraction is common, occurs early post-operatively, with or without repair continuity as assessed by traditional imaging, and significantly correlates with clinical outcomes. The immediate and highly significant consequence of this finding would be a paradigm shift in the investigators' understanding of tendon repair healing, now incorporating the magnitude, timing and location of tendon retraction as well as the continuity of the repaired tissue. This information would yield a more precise understanding of rotator cuff tendon healing, allowing for advances in treatment strategies that improve surgical healing and clinical outcomes and result in more durable rotator cuff repairs over time.
