 Verification of subject adherence to the post-operative follow-up visit schedule will be overseen by the PI throughout the course of the project. Weekly communication with sub-investigators will take place in order to review any outstanding concerns including recruitment effort, surgery schedules, and post-operative visit timelines. Arrangements for additional visits will also be reviewed and scheduled if medically necessary depending on individual patients post-operative clinical course. Patients will be assigned to each group during the period of September 2015 through July 2016 and followed as part of the study for 3 months post-operatively.
