The purpose of this study is to investigate the efficacy of a positive affect enhancing intervention designed to reduce pain and augment reward system function in knee osteoarthritis (KOA) patients undergoing total knee arthroplasty (TKA). The scientific premise is that patient use of a positive emotion generative practice - savoring meditation, which has been demonstrated to reduce pain in experimental laboratory settings, enhanced with a pain neuroscience education component about reward system dysfunction as a chronic pain mechanism - is optimally suited to reduce postsurgical pain and augment reward system functioning relative to a Pain Self-Management and Education (PSME) condition. We will randomize 150 patients with KOA undergoing unilateral TKA to a brief, 4-session (20-30 minutes each) course of Savoring Meditation (SM; n = 75) or PSME (n = 75) delivered remotely by trained interventionists in a one-on-one format. We will assess pain and as well as pain-related risk and protective factors both via questionnaire and via weeklong ecological momentary assessment (EMA) data bursts on the following schedule: baseline, post-surgery, and 3-month follow-up. In addition, participants will attend laboratory testing sessions at baseline and 6-weeks post-surgery, during which affective pain modulation and electroencephalographic (EEG) brain biomarkers associated with pain and affect will be recorded. Participants in SM be encouraged to practice their savoring for 5 minutes/day during the week following surgery, as well as to use it to manage pain flares in a self-directed manner.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
