Factors contributing to recurrent dislocation, revision stabilization, and complications requiring reoperation after an initial shoulder stabilization procedure for instability have not been evaluated on a population level.(1) To define the rate of ipsilateral revision stabilization, contralateral primary stabilization, postoperative dislocation, and complications after primary shoulder stabilization in a population cohort. (2) To understand which risk factors among patient, surgical, and provider factors influence these outcomes.Cohort study; Level of evidence, 3.All residents of Ontario, Canada, aged 16 to 60 years undergoing primary shoulder stabilization between July 2003 and December 2008 were identified from billing and hospital databases. Separate Cox proportional hazards survivorship models were built for the outcomes revision stabilization and postoperative physician-documented shoulder relocation (minimum 2-year follow-up). Model covariates included patient demographics (age, sex, preoperative dislocations), provider characteristics (surgeon volume, hospital academic status), and type of surgery (open, arthroscopic). The frequency and risk factors for contralateral stabilization were identified.A total of 5904 patients (80.6
