Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

P5 is planned as a prospective observational study, collecting evidence-based perioperative data on patient history and demographics, physical function, cognitive measures, psychological, and biological markers associated with increased pain susceptibility, and psychophysical measures of pain processing.

The study will use daily ecologic momentary assessment (EMA) of physical and emotional parameters, and collect data on perioperative events.

Follow up will occur 3 months and 6 months postoperatively.
