All patients will receive non-labeled pills identical in appearance from our pharmacy, to be taking once every other day. In the study group, these will contain 50 mg of clomiphene citrate. In the control group, these will be placebo. These will be taken every other day for seven months beginning four weeks prior to surgery and extending for six months after surgery. After enrollment patients will be randomized. Patient will be assigned to the 2 groups using a permuted block randomization scheme with blocks of size 2, 4, and 6. Prior to initiation of the study opaque sealed envelopes will be prepared and thoroughly shuffled and then used sequentially during the study. These randomization assignments will be available to the pharmacy in a web-based format or by cards in sealed envelopes. A nonparticipant in the study (the pharmacy at our institution) will administer this process.

The operative protocol will be standardized in all patients. Both the operative protocol and post-operative rehabilitation protocol will be per our standard of care, without alteration. An arthroscopic approach will be used. In all cases a double-row rotator cuff repair using triple-loaded anchor(s) on the medial row will be used. Post-operatively all patients will be placed in a sling for six weeks. Active range of motion exercises will begin at six weeks post-operatively and strengthening will be delayed until 12 weeks post-operatively. In all phases of care our peri-operative and post-operative protocol for study patients will be similar to our current clinical practice to ensure generalizability.
