The primary purpose of this study is the determine whether a 15 minute Mindfulness Meditation (MM) administered at the preoperative appointment prior to primary unilateral total joint arthroplasty (TJA) results in any improvement in Pittsburg Sleep Quality Index (PSQI) score, a validated metric for sleep quality, at 2, 6 or 12 weeks post-operatively.

The primary purpose of this study is the determine whether a 15 minute Mindfulness Meditation (MM) administered at the preoperative appointment prior to primary unilateral total joint arthroplasty (TJA) results in any improvement in Pittsburg Sleep Quality Index (PSQI) score, a validated metric for sleep quality, at 2, 6 or 12 weeks post-operatively. We hypothesize that patients in the MM cohort will have lower PSQI scores, indicating higher sleep quality, at both post-operative time points. Secondary aims include characterizing differences between cohorts in Visual Analog Scale (VAS) for pain, Epworth Sleepiness Scale (ESS) scores, Patient Reported Outcome Measurement Information System - Sleep Disturbance - Short Form, and Knee Injury and Osteoarthritis Outcome Scores (KOOS) at 2, 6 and 12 weeks following TJA.

Inclusion Criteria:

• Patients undergoing primary unilateral total joint arthroplasty at Colorado Joint Replacement
• Between the ages of 18 and 90 years old will be included in the study.

Exclusion Criteria:

• Simultaneous total joint arthroplasty
• Uni-compartmental knee arthroplasty
• Revision surgery for infection, fracture or other indication.
• History of Drug or Alcohol Abuse
• Patients who are unable to present at a standard pre-operative appointment within 4 weeks prior to scheduled surgery will also be excluded, as the MM intervention would not be possible to administer.
