This project will involve planning and implementing a two-arm prospective pragmatic cohort clinical trial in patients with known rotator cuff tears.

This project will involve planning and implementing a two-arm prospective pragmatic cohort clinical trial in patients with known rotator cuff tears. Pragmatic or effectiveness clinical trials reflect real world settings and thus have greater external generalizability than efficacy trials. The evaluation component in this trial will be three-fold: first, the study team will compare the success of patients undergoing operative versus non-operative management and identify which variables predict success in each group; second, investigators will attempt to predict which patients end up choosing, along with their care giver(s), operative versus non-operative management by examining the predictive capability of a selection of variables; third, investigators will evaluate the clinical research site(s), personnel, and implementation processes for their capability to implement clinical trials with the intent of planning for a future large multi-site clinical trial building on the results of the present study.
