Study Overview
Brief Summary
The purpose of this study is to collect information to evaluate the role of the psychogenic component of pain induced by anxiety on postoperative outcomes in major orthopaedic surgery and to determine whether hypnosis therapy provided during the perioperative period will lead to decreased use of opioid therapy. Patients are randomly assigned to one of two treatment groups: (I) usual care, or; (II) hypnotherapy treatment. Patients have an equal chance of being assigned to one of the two groups.

- •18 years of age or older

Arms & Interventions
Hypnosis Therapy Group
Experimental: Hypnosis Therapy Group
Patients will receive questionnaires to establish their attitudes/beliefs toward hypnosis, baseline pain, anxiety, & knee function. 7 days prior to surgery, they will receive a pre-recorded video (-19 min) of guided hypnosis to be watched at least 1x/day, until surgery. Postoperative course will be otherwise completely standard of care, including a clinic visit at 10 days after surgery, where they will be given these same questionnaires. Patients will answer them again on postoperative day 49, constituting a study endpoint. Access to pain medication & study doctor will be the same as any total knee arthroplasty regardless of study participation.
Intervention: Hypnosis Therapy (Behavioral)
Control Care Group
No Intervention: Control Care Group
Patients will receive questionnaires to establish their attitudes/beliefs toward hypnosis, baseline pain, anxiety, & knee function. 7 days prior to surgery, they will receive a pre-recorded video (-19 min) of guided information to be watched at least 1x/day, until surgery. Postoperative course will be otherwise completely standard of care, including a clinic visit at 10 days after surgery, where they will be given these same questionnaires. Patients will answer them again on postoperative day 49, constituting a study endpoint. Access to pain medication & study doctor will be the same as any total knee arthroplasty regardless of study participation.
