Research Summary

Outcomes Research: The focus of our research is to analyze all outcomes in order to improve care. Our prospective registry allows us to measure patient-reported outcomes including the process of recovery, the amount of pain and improved function, and the durability of the recovery. Together with other analysis of groups of patients our focus is to improve the value of the care delivered to all patients with shoulder problems.
