This will be a prospective, randomized, double-blinded placebo controlled study. Randomization will be performed by a random numbers table. Envelopes will be sealed with the accompanying randomization group.Patients will be eligible for inclusion in the study if they have a full-thickness rotator cuff tear that has been deemed reparable by preoperative MRI. They will be included in the study if they are medically stable to undergo the surgery and consent to involvement in the study.
Patients consenting to the study will undergo arthroscopic rotator cuff repair by one of the two senior authors. The surgery will be performed as an outpatient procedure under general anesthesia. The procedure will be performed utilizing the standard techniques of the senior authors. All concomitant pathology found at the time of arthroscopy will be treated in the usual appropriate fashion. At the completion of the rotator cuff repair, patients will be randomly allocated to one of three groups. This will be done by opening a sealed envelope with the randomization allocation. The patients will either be placed into the study group, the placebo group or the control group.
